Other Parts Discussed in Thread: SN74CB3Q3257, SN74CBT3257, SN74CBT3257C, TS5N412, CD74HCT4066
Hi,
I would like to know if we can use this switch generically for analog applications.
I've been using the NXP NX5DV330PW, and observed strange behavior. This TI part is listed as a direct replacement for the NXP part on Digi-key.
My problem with the NXP (hopefully not the TI part) is that although the RDON is supposed to be 10 Ohms, the voltage difference between input/output is 1V. I input a 5V pulse and observe a 4V pulse at the output with a scope. the load is an OP-Amp. (high impedance).
We want to use the chip to switch TTL or RS422 pulses, and also some analog signals in other applications.
The pules are about 100uS, the frequency up to 200Hz.
We power the IC with 5V, and the signals trough the input/outputs are up to 5V.
we do not toggle the switch during operation, we select with a jumper which switch to use (S1 or S2).
Thanks,
Victor
