This document describes the features and characteristics of the 74HC/HCT14 hex inverting Schmitt trigger. They are high-speed Si-gate CMOS devices and are compatible with low power Schottky TTL (LSTTL).
The document is a product specification sheet for the Philips 74HC/HCT14, which are high-speed Si-gate CMOS devices. These chips provide six inverting buffers with Schmitt-trigger action and are pin compatible with low power Schottky TTL (LSTTL). They are designed to transform slowly changing input signals into sharply defined, jitter-free output signals.
| Device Type | Hex inverting Schmitt trigger |
|---|---|
| Logic Category | SSI |

The device is suitable for use in wave and pulse shapers, astable multivibrators, and monostable multivibrators.
The typical propagation delay is 12 ns when the supply voltage is 5 V.
The typical propagation delay is 34 ns when the supply voltage is 4.5 V.
