SN74ABT373DBR

Latches Overview

The SN74ABT373DBR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the ABT logic series. It features eight independent D-type latches with tri-state outputs in a 20-SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Key electrical parameters include a propagation delay of 8.6 ns, low-level output current of 24 mA, and high-level output current of 3 mA. It functions reliably across an operating temperature range of 0°C to 70°C.

Latches Feature Summary

• Provides eight independent transparent D-type latches for data storage applications
• Features tri-state outputs to facilitate bus-oriented memory management
• Supports direct interface with TTL logic systems through compatible input structures

Latches Applications

• Bus-oriented memory mapping
• Register banks
• I/O port buffering

Latches Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 surface-mount package and tape-and-reel shipping configuration. Confirm that the ABT series specifications align with system requirements for 5V operation and 8.6 ns timing constraints. Ensure compatibility with existing PCB footprints designed for 20-pin small-outline packages.

Latches Selection Notes

Select this component when designing systems requiring octal latching with tri-state capability at 5V logic levels. The ABT series offers faster switching speeds compared to standard LS or HC families while maintaining TTL input compatibility. Consider the 20-SSOP package for space-constrained surface-mount designs requiring robust drive strength.

Latches Part Context

This part belongs to the Texas Instruments SN74ABT family, which combines advanced bipolar-transistor technology with CMOS features. The ABT series is designed for high-speed applications requiring low power consumption and wide voltage tolerance. The SN74ABT373 specifically addresses needs for parallel data retention in digital communication and computing architectures.

Latches Replacement Considerations

SN74ABT373ADBR (same function, different manufacturer suffix) and SN74ABT373DWR (same function, SOIC-20 package). Verify pinout compatibility before substitution.
