FEATURES
GENERAL DESCRIPTION
The 74HC/HCT9115 are high-speed Si-gate CMOS
devices and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT9115 are nine wide Schmitt trigger buffer
with open drain outputs and Schmitt trigger inputs.

notes 1 and 2
The Schmitt trigger action in the data inputs transform
slowly changing input signals into sharply defined
jitter-free output signals.
The 74HC/HCT9115 have open-drain N-transistor
outputs, which are not clamped by a diode connected to
V
output may be pulled to any voltage between GND and
V
LOW-to-HIGH or HIGH-to-LOW level shifter. For digital
operation and OR-tied output applications, these devices
must have a pull-up resistor to establish a logic HIGH level.
The “9115” is identical to the “9114” but has non-inverting
outputs.
