SN74HC373DWR Description

Short technical summary and product information.

The SN74HC373DWR from Texas Instruments is an octal transparent D-type latch featuring 3-state outputs. This device is designed for driving highly capacitive or low-impedance loads, making it suitable for buffer registers, I/O ports, and bidirectional bus drivers.

 

Key electrical characteristics include a wide operating voltage range of 2 V to 6 V, a low power consumption of 80 µA maximum ICC, and a typical propagation delay of 13 ns. The outputs provide ±6 mA of drive at 5 V, and the input current is a low 1 µA maximum.

 

This latch features eight high-current latches in a single package, offering full parallel access for loading. The device operates within a temperature range of -40°C to 85°C. It is housed in a 20-SOIC (Surface Mount) package, specifically a 20-SOIC (0.295", 7.50mm Width).

 

The SN74HC373DWR is particularly useful in applications requiring transparent latching functionality where data needs to be held stable until a latch-enable signal changes. Its 3-state outputs allow for efficient bus interfacing.
