Part Number: SN74AHCT123A Other Parts Discussed in Thread: SN74LS123 Hello E2E Experts,
Good day.
On the LS123 datasheet, there is a protection died as seen in the image below.
On SN74AHCT123A datasheet page 7, there is no diode as seen in the snippet…
Part Number: SN74AHCT123A Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I was wondering whether TI could provide the SPICE model of component SN74AHCT123A. I am in the process of circuit design.
I have seen that you do…
Other Parts Discussed in Thread: SN74LS221 , SN74AHCT123A , SN74AHC123A Hi all Would you mind if we ask SN74AHCT123A and SN74LS221? <Question1> How much is the minimum wide pulse? Using each devices and Cext/Rext, our customer would like to calculate wide…
1.1 V at pin 1 is not a valid logic voltage.
LS family devices require quite a lot of input current (see I IL in the electrical characteristics). I strongly suggest to use a CMOS device like SN74AHCT123A.
If you must use the LS device, make R167 and R169…
Chengcheng,
The typical propagation delay between S1 going low and purple going high is 100nS. There is no minimum or maximum propagation delay stated, so this might use up the whole 30nS tolerance budget. There is also a larger propagation delay for…
Other Parts Discussed in Thread: SN54AHCT123A , SN74AHCT123A , SN74LVC1G123 Hello,
I am fighting an obsolescent issue. I have an old design that uses 96LS02 which is not available and/or recommended for new designs. I have done a quick cross reference search…
Satoshi-san,
sn74ahct123a would be a low cost solution. For connection advice, try this device name in the logic forum.
TLC555 would work if the input was inverted (use standard mono-stable setup)
