SN54HC32 and SN74HC32 are quadruple independent 2-input positive-or gates. They have a wide operating voltage range of 2V to 6V, can drive up to 10 LSTTL loads, have low power consumption (maximum 20µA ICC), short propagation delay (typical value of 8ns), high output drive capability (±4mA at 5V), and low input current (maximum 1µA).
The SN54HC32 and SN74HC32 devices are quad 2‑input positive‑OR gates offered in a variety of packages (PDIP, SOIC, SSOP, TSSOP, etc.). The document provides ordering information, electrical characteristics, absolute maximum ratings, recommended operating conditions, and mechanical package data.
Key features include a wide operating voltage range of 2 V to 6 V, typical propagation delay of 8 ns, output drive capability of up to 10 LSTTL loads, and operation over –55 °C to 125 °C (SN54HC32) or –40 °C to 85 °C (SN74HC32).
| Operating voltage range | 2 V to 6 V |
