Hi ,

I want to find TTL craft product instead of CMOS Craft product , as below ，all CMOS product, could you help me find TTL product to replace them ?

1.SN74HC14DR

2.CD74HC04M

3.CD74HC32M96

4.CD74HC08M96

5.CD74HC165MT

Why? If you need to handle TTL signals, you can use CMOS devices with TTL-compatible inputs.

TTL:

SN74LS14, SN7414
SN74ALS04B, SN74LS04, SN7404
SN74ALS32, SN74LS32, SN7432
SN74ALS08, SN74LS08
SN74ALS165, SN74LS165A

TTL compatible:

SN74AHCT14, SN74HCT14
SN74AHCT04, SN74HCT04
SN74AHCT32, CD74HCT32
SN74AHCT08, SN74HCT08
CD74HCT165

HCS devices do not have TTL-compatible inputs. What is the problem you're trying to solve?
