74AHC14-Q100; 74AHCT14-Q100
Hex inverting Schmitt trigger
Rev. 1 — 9 July 2012
Product data sheet
1. General description
The 74AHC14-Q100; 74AHCT14-Q100 is a high-speed Si-gate CMOS device and is pin
compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with
JEDEC standard No. 7A.
The 74AHC14-Q100; 74AHCT14-Q100 provides six inverting buffers with Schmitt trigger
action. They are capable of transforming slowly changing input signals into sharply
defined, jitter-free output signals.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
