SN74LS373DW

Latches Overview

The SN74LS373DW is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the 74LS logic series. It features eight non-inverting D-type latches with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports a propagation delay of 18ns at 5V. It provides a low-level output current of 32mA and a high-level output current of -2.6mA. The component functions across a temperature range of 0°C to +70°C.

Latches Feature Summary

• Octal D-type transparent latch architecture with shared latch enable and output enable inputs
• Three-state outputs designed for direct bus organization system applications
• Non-inverting polarity ensuring true logic transmission from input to output

Latches Applications

• Bus organization systems requiring data storage and isolation
• Microcontroller-based embedded designs utilizing address or data latching
• General-purpose digital logic circuits requiring tri-state buffering

Latches Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as environmental certifications may vary by production batch. Ensure the supplier provides valid traceability for the Texas Instruments brand to guarantee component authenticity and performance reliability.

Latches Selection Notes

Select this component for applications requiring LSTTL-compatible logic levels with three-state bus driving capabilities. The SN74LS373DW is suitable where moderate speed and standard drive strength are sufficient. Consider alternative packages such as PDIP or NSR if through-hole or tape-and-reel assembly methods are required instead of the standard SOIC form factor.

Latches Part Context

This part belongs to the widely adopted 74LS family of bipolar logic devices, known for compatibility with standard TTL interfaces. The SN74LS373 specifically addresses the need for parallel data storage in digital systems. Its design facilitates efficient data handling in microprocessor architectures by providing stable latched outputs while maintaining bus isolation during inactive periods.
