SN74AHC373PWG4

Overview

The SN74AHC373PWG4 is an octal transparent D-type latch manufactured by Texas Instruments. It features eight D-type latches with 3-state outputs, housed in a 20-TSSOP package. The device operates within a supply voltage range of 2V to 5.5V and supports a working temperature range from -40°C to 85°C. Key electrical parameters include a propagation delay of 1ns and output currents of 8mA for both high and low states. The component is RoHS3 compliant and has reached end-of-life status.

Feature Summary

• Contains eight independent transparent D-type latches with 3-state outputs
• Operates across a wide supply voltage range from 2V to 5.5V
• Provides fast switching performance with a propagation delay of 1ns
• Supports surface mount installation in a compact 20-TSSOP package

Applications

• Data register applications requiring parallel-to-serial conversion

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Verification of availability should focus on alternative sources or direct replacement parts rather than new production units. Buyers must confirm the specific revision and authenticity of any remaining stock, as the part is no longer actively manufactured. Cross-referencing with current inventory lists is essential before finalizing procurement decisions.

Selection Notes

Designers should consider the SN74AHC373PWR as a direct replacement due to identical functionality and pinout compatibility. Alternative packages such as the SOIC variant (SN74AHC373DWR) are available if board space constraints differ. Ensure that the selected substitute maintains the required 3-state output capability and operating voltage range for seamless integration into existing designs.

Part Context

The SN74AHC373PWG4 belongs to the Texas Instruments 74AHC series of high-speed CMOS logic devices. This series is designed for low power consumption and high-speed operation, making it suitable for various digital logic applications. The 'G4' suffix indicates compliance with specific environmental standards, including RoHS3 regulations, ensuring suitability for modern manufacturing processes.

Replacement Considerations

The SN74AHC373PWR is confirmed as a direct replacement. Other compatible variants include the SN74AHC373PW and the SN74AHC373DWR.
