74F373MSAX

Latches Overview

The Fairchild Semiconductor 74F373MSAX is an octal transparent latch featuring three-state outputs, designed for bus-organized system applications. It contains eight D-type latches within a single package. The device operates with a supply voltage range of 4.5V to 5.5V and utilizes a 20-pin SSOP surface-mount package. Key electrical parameters include a propagation delay of 5.3ns and output currents of 3mA high and 24mA low. It functions within an operating temperature range of 0°C to 70°C.

Latches Feature Summary

• Provides eight transparent latches in a single integrated circuit package
• Features three-state outputs suitable for direct bus interfacing
• Ensures data retention when the latch enable input transitions from high to low

Latches Applications

• Bus organized system data storage
• Interface between microprocessors and peripheral devices
• Temporary data holding in digital logic circuits

Latches Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm lot codes and date codes against current inventory records. Ensure packaging integrity matches standard reel specifications for surface mount assembly processes. Check for RoHS compliance status if required by specific environmental regulations.

Latches Selection Notes

Select this component for designs requiring high-speed data latching with bus isolation capabilities. Consider the 20-SSOP package dimensions for PCB layout constraints. Evaluate the 5.3ns propagation delay against system timing requirements. Ensure power supply stability within the specified 4.5V to 5.5V range for reliable operation.

Latches Part Context

This part belongs to the 74F logic family, known for fast switching speeds comparable to standard TTL but with improved performance characteristics. The 74F373 variant specifically addresses the need for octal data storage in high-speed digital systems. It serves as a critical interface element in complex electronic architectures requiring synchronized data transfer.

Latches Replacement Considerations

Texas Instruments SN74F373DBR is a confirmed direct substitute. Verify pin compatibility and electrical specifications before implementation.
