SN74HC373N Description

Short technical summary and product information.

The SN74HC373N from Texas Instruments is an octal transparent D-type latch featuring 3-state outputs. This device operates across a wide voltage range of 2 V to 6 V, making it versatile for various applications. Its high-current 3-state outputs can drive up to 15 LSTTL loads, and it offers ±6-mA output drive at 5 V.

 

Designed for driving highly capacitive or relatively low-impedance loads, the SN74HC373N is ideal for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight latches are transparent D-type, meaning the Q outputs follow the D inputs while the latch-enable (LE) input is high. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.

 

This component has a typical propagation delay of 13 ns and a low power consumption of 80 µA maximum ICC. It features a low input current of 1 µA maximum. The SN74HC373N is available in a 20-PDIP through-hole package, with an operating temperature range of -40°C to 85°C.
