The 74HC/HCT03 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/HCT03 provide the 2-input NAND function. The 74HC/HCT03 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 LOW, 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 document is a product specification datasheet for the 74HC/HCT03, a high-speed Si-gate CMOS integrated circuit. These devices are pin compatible with low power Schottky TTL (LSTTL) and feature standard open-drain N-transistor outputs that allow them to be used as level shifters when combined with a pull-up resistor.
The datasheet provides comprehensive technical data including quick reference parameters, pin descriptions, functional diagrams, absolute maximum ratings, DC and AC electrical characteristics for both HC and HCT variants, application information regarding pull-up configurations, and references to package outlines.
