SN74F373DWG4

Overview

The SN74F373DWG4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74F logic series. It features eight D-type latches with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 8.6 ns at 5 V. Output drive capabilities include a low-level output current of 24 mA and a high-level output current of -3 mA. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides octal data storage via transparent D-type latching mechanism
• Integrates three-state outputs for effective bus driving applications
• Utilizes FAST TTL logic technology for high-speed performance

Applications

• Parallel-to-serial data conversion circuits
• Register files in digital systems
• Bus-oriented memory mapping

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the package type matches the required 20-SOIC footprint. Ensure the operating temperature range aligns with the commercial specification of 0°C to +70°C. Cross-reference the manufacturer part number directly with official TI databases to confirm current production status and availability.

Selection Notes

Select this component when high-speed latching is required within standard 5V logic environments. The 74F series offers faster switching speeds compared to standard 74LS equivalents. Consider the three-state output feature if the design requires sharing a common data bus among multiple devices. Verify that the input logic levels are compatible with the driving source signals.

Part Context

This component is part of the broader SN74F373 family of octal transparent D-type latches. Variations exist in packaging options such as DIP, SSOP, and TSSOP, as well as different suffixes indicating environmental compliance or tape-and-reel configurations. All variants share the core logical functionality defined by the 74F series specifications.

Replacement Considerations

Direct pin-compatible alternatives within the same family include SN74F373DWR and SN74F373DR. Other manufacturers may offer equivalent parts under different naming conventions, but electrical characteristics must be verified against the original datasheet.
