SN74S373N Description

Short technical summary and product information.

The SN74S373N is an 8-bit octal D-type transparent latch manufactured by Texas Instruments. This component is designed for driving highly capacitive or low-impedance loads, making it suitable for bus-organized systems without requiring additional interface or pullup components. It features 3-state bus-driving outputs and full parallel access for loading.

 

Key electrical specifications include a maximum clock frequency of 50 MHz and a typical propagation delay of 7 ns. The device operates within a voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C. The output type is Tri-State, with IOL (Output Low Current) maximum of 24 mA and IOH (Output High Current) maximum of -3 mA. The supply current is a maximum of 100 mA.

 

This latch is housed in a 20-pin PDIP package and is designed for through-hole mounting. The SN74S373N is particularly useful for implementing buffer registers, I/O ports, and bidirectional bus drivers in various digital logic applications.
