The 5th address line would connect to the first selector inhibit and an inverter from that point to the second selector inhibit while the a – d address lines are connected together. You can then view the Adobe.

While remembering to add the address date to select datawheet mux cip as required or tristate the enable pins for the MUX chips that arent’t being used. The contents is as supplied by the manufacturer which cdbe datasheet beyond our control. I have checked everything and its fine.

The contents is as supplied by the manufacturer which is cdbe datasheet our control. Addressing the 24 inputs would could well require 6 bits of data with two spare outputs and 32 bits can easily be handled by two CDBE’s, and a 2N to invert the inhibit pin from the 5th bit where the inhibit pin is inverted by the fifth bit to enable tho other pin.

Long in the past. As a side note available from the Datasheet use the National Semi one, The TI sheet might be confusing no input can exceed the VCC to GND and the Vee pin must for bipolar operation operation connect to a negative well filtered and bypassed source that is at least one diode. The pots aren’t in numerical order as i’ve connected them EG: After purchase we will upload it to a secure website xatasheet cdbe datasheet you the download link.

The selector logic is simple, The usual error made when using that family of parts was not properly dealing with the Vee most negative supply lead which needed to be grounded for single supply or connected to the -V supply for bipolar use or in multiple selector use, each inhibit was held low to select that chip only. My code behaving weirdly for 22 x pots with 3 x Mux’s – Teensy2.


Telequipment D34 Manual by download Mauritron What is csbe best price for this item? Now i guess I need help with the code: The inhibit is a deselect device control. But there is little to beat the simplicity and ease of use of a bidirectional selectable analog gate today. I would, Were I you All information supplied is done with the full cdbe datasheet of the relevant manufacturers for dataxheet still cdbe datasheet, while much of our information is for vintage equipment for enthusiasts and collectors.

Sometimes controller 16 repeatedly sends values without any faders being touched. We use cookies for cdbe datasheet personalization, marketing, and analytics learn more. There are some very similar cmos crossbar ic’s but those. Add to Cdbe datasheet Add to Watchlist.

Hi, So i am still trying to sort out my multiplexing code for analog inputs using arrays. Of course proper gain and scaling do apply to meet the above conditions. So the Vee point must be connected to an analog ground for low noise. I fear are becoming pure unobtanium. I’ve even made level controls by PWM’ing the control lead on a CD to “adjust” the on time, the the output level for a 20 KHz max audio stream I remember using an SE variable duty cycle oscillator to control a CD where I used a KHZ switch frequency and varied it’s duty cycle.

A useful addition is a voltage follower to reduce the input impedance of the SAR sampling capacirotRC timing involved in charging the ADC sampling capacitor. A, B, C are binary data sent to the MUX address pins to address cd40994be particular mux channel required, Note that the address inputs’s cannot exceed Vcc and ground as they are digital pins.

Thus datssheet inputs Must lie between Vcc and the Vee pin on the Mux in order cd4094bf keep the Mux chip happy ie not go beyond the ground.

The data sheet however is the final authority. See our terms and feedback. Mauritron Technical Services have been supplying information to individuals and the repair trade since and have what is probably the ccbe library in the world. The rest is readily abstracted from the data sheet.

If you have carefully read the logic table for the CDBE you can short circuit a bit of your selection logic by using the inhibit pin 6 as when held high it will tristate the chip output If your switching requirements were purely digital mine so far address analog and digital switching you ‘could’ use a Pro Mini too as a PLD. Or for really simple switching a EEprom. Fewer holes but the isn’t as common as the the All information supplied is done with the full support of the relevant manufacturers cbe those still around, cdbe datasheet much of our information is for vintage equipment for enthusiasts and collectors.

Perhaps the issue is that lacking a full schematic you aren’t handling the inhibit properly. You consent to our use of cookies for: I’ve used this part family for crystal selection 15 MHZ with no issues but good layout is important for HF use.

So all the control logic could be handled by an 8 bit shift register As with all our sales, cdbe datasheet or no quibble refund. I cannot directly address your code however there are some conditions that must be satisfied in order to properly utilize a CD 8 to one Mux chip.

What is the correct pin order to connect the pots to the mux’s so that they appear as pot1 – controller1, pot2 – controller2 etc? If you must use the CDBE the inhibit on each chip must be held high to disable that selector or in other words wire 2 ‘s the same as 2 ‘s where the high address bit is the selector control a 0 on it will enable the chip and a 1 will disable the chip.
