SN74F2373DW

Overview

The SN74F2373DW is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It integrates eight latches in a single package, featuring buffered control inputs and full parallel access for loading. The device includes nominal 25-ohm sink resistors to reduce overshoot and undershoot on bus lines. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from 0°C to 70°C. The component utilizes a 20-pin Small-Outline (DW) package.

Feature Summary

• Integrates eight transparent D-type latches with 3-state true outputs in a single package
• Includes internal 25-ohm sink resistors designed to reduce signal overshoot and undershoot
• Features buffered output-enable input to place outputs in high-impedance state without affecting internal latch operations
• Supports full parallel access for loading via buffered control inputs

Applications

• Bus line driving applications requiring interface or pullup components elimination
• Data storage circuits utilizing transparent latch functionality
• Digital logic systems requiring 3-state output control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm active status and packaging details. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure the selected variant corresponds to the required pin count and package type for PCB layout compatibility.

Selection Notes

Select this component when designing systems requiring octal data latching with integrated bus termination characteristics. The inclusion of 25-ohm sink resistors makes it suitable for high-speed digital buses where signal integrity is critical. Verify that the 3-state output capability aligns with the system's multiplexing or tri-state bus architecture requirements.

Part Context

This part belongs to the SN74F series of logic devices produced by Texas Instruments. It is functionally related to other octal latches such as the SN74F373 but distinguishes itself through the integration of internal 25-ohm sink resistors. The DW package designation indicates a standard plastic small-outline configuration available in tube packaging.
