SN74AHCT32QPWR

Overview

The SN74AHCT32QPWR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to 125°C. The device features TTL-voltage compatible inputs with high-level input voltage (VIH) at 2 V and low-level input voltage (VIL) at 0.8 V. Output drive capabilities include ±8 mA for both high and low states. Propagation delay ranges from 5 ns to 9 ns depending on load capacitance, which can be 15 pF or 50 pF.

Feature Summary

• Implements the Boolean function Y = A + B using four independent gates
