SN74AHCT16373DLR

Overview

The SN74AHCT16373DLR is a 16-bit transparent D-type latch manufactured by Texas Instruments. It features two independent circuits with tri-state outputs, housed in a 48-SSOP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports propagation delays as low as 1ns. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides 16-bit data storage capability through two independent octal latch circuits.
• Features high-speed performance with propagation delays down to 1 nanosecond.
• Includes tri-state outputs for effective bus driving and system isolation.

Applications

• High-speed data buffering in digital systems
• Register applications requiring fast clock-to-output timing
• Bus-oriented memory architectures

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the 48-SSOP package and reel packaging configuration. Confirm that the 1ns propagation delay specification aligns with your target operating voltage and load conditions. Ensure compatibility with 5V logic levels given the AHCT series requirements.

Selection Notes

Select this component when 16-bit latching with ultra-fast switching speeds is required in a 5V environment. The AHCT series ensures CMOS compatibility while maintaining TTL input thresholds. Consider the SSOP package constraints for PCB layout density compared to larger form factors.

Part Context

This part belongs to the 74AHCT logic family, designed for high-speed operation at 5V. It serves as a modern replacement for older 74HCT variants, offering improved speed and lower power consumption while maintaining pinout compatibility with standard logic families.

Replacement Considerations

Public confirmed substitute: SN74AHCT16373DGGR (Texas Instruments). Verify package differences between SSOP and TSSOP if physical footprint changes are acceptable.
