The MC74HC14ADR2G is a Hex Inverter with Schmitt trigger input. The MC74HC14A is identical in pinout to the LS14, LS04 and the HC04. The device inputs are compatible with standard CMOS outputs, with pull-up resistors, they are compatible with LSTTL outputs.
Outputs directly interface to CMOS, NMOS and TTL
1mA Low input current
High noise immunity characteristic of CMOS devices
In compliance with the JEDEC standard No. 7A requirements
