SN74AHC373PWR

Overview

The SN74AHC373PWR is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum low-level output current of 32 mA with a high-level output current of -8 mA. The device features a propagation delay of 14.9 ns at 5 V and 9.2 ns at 3.3 V, with a static current consumption of 4 uA. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 20-pin TVSOP package.

Feature Summary

• Octal transparent D-type latch architecture providing eight independent data storage channels
• Wide operating voltage capability supporting systems from 2 V to 5.5 V
• High drive strength with low-level output current reaching 32 mA for robust signal integrity

Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital logic designs
• Buffering and latching of address/data buses in microprocessor systems

Procurement Notes

Verify the specific suffix PWR indicates the tape-and-reel packaging format compatible with automated surface-mount assembly processes. Confirm that the component meets RoHS compliance standards as specified in the manufacturer documentation. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape handling requirements during production integration.

Selection Notes

Select this component when an octal latch with wide voltage flexibility is required for general-purpose digital applications. The TVSOP-20 package offers a compact footprint suitable for space-constrained designs. Consider the 32 mA low-level drive capability for direct interfacing with loads requiring higher current than standard CMOS outputs provide without external buffering.

Part Context

This part belongs to the SN74AHC373 series of octal transparent D-type latches produced by Texas Instruments. The AHC logic family provides advanced performance characteristics compared to older technologies, balancing speed and power consumption. The device serves as a fundamental building block for sequential logic circuits requiring parallel data storage and controlled output enablement.

Replacement Considerations

SN74AHC373PWG4 is listed as a discontinued alternative. SN74AHC373DGVR and SN74AHC373DWR are available direct replacements from Texas Instruments offering identical logical functionality in different package variants.
