TC74HC279AF Description

Short technical summary and product information.

The Toshiba TC74HC279AF is a high-speed CMOS Quad S-R Latch fabricated with silicon gate C2MOS technology. It offers high-speed operation similar to LSTTL while maintaining low CMOS power dissipation. Each latch has independent Set and Reset inputs that are active low. The device operates over a wide voltage range of 2 V to 6 V and features a typical propagation delay of 12 ns at 5 V.

 

This latch is designed with protection circuits on all inputs against static discharge or transient excess voltage. It is pin and function compatible with the 74LS279. The TC74HC279AF comes in a SOP16 package, suitable for surface mounting.

 

Key electrical characteristics include a maximum quiescent current of 2 µA at 25°C, high noise immunity, and symmetrical output impedance. The device is RoHS3 compliant.
