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

VCC. In the OFF-state, i.e. when one input is HIGH, the

output may be pulled to any voltage between GND and

VOmax. 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.
