SN74HC27DR Description

Short technical summary and product information.

The SN74HC27DR from Texas Instruments is a logic IC containing three independent 3-input NOR gates. Each gate performs the Boolean function Y = A + B + C in positive logic. This device is designed for a wide operating voltage range of 2V to 6V and operates reliably across a broad temperature spectrum from -40°C to +85°C.

With a package type of 14-SOIC, the SN74HC27DR is suitable for surface mount applications. It offers a drive strength of 5.2mA and a maximum propagation delay of 15ns at 6V with a 50pF load capacitance. The buffered inputs and significant power reduction compared to LSTTL logic make it an efficient choice for various digital circuit designs.

This NOR gate is part of the 74HC family, known for its high noise immunity and speed. Its versatility makes it applicable in numerous digital systems requiring basic logic functions.
