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.
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
CC
. In the OFF-state, i.e. when one input is HIGH, the
output may be pulled to any voltage between GND and
V
Omax
. This allows the device to be used as a
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.
