SN74AHCT594DBR

Shift Registers Overview

The SN74AHCT594DBR is an 8-bit serial-in, serial/parallel-out shift register with output latches manufactured by Texas Instruments. It belongs to the 74AHCT logic family and operates within a supply voltage range of 4.5 V to 5.5 V. The device features TTL-compatible inputs and push-pull outputs. It is housed in a 16-SSOP package with a width of 5.30 mm. The component supports a wide operating temperature range from -40°C to +125°C and includes a serial input, clock input, and storage register clock input for data control.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion capabilities with dedicated storage register functionality
• Features TTL-compatible input levels for direct interfacing with standard logic systems
• Delivers push-pull output stages for robust signal driving

Shift Registers Applications

• Data acquisition systems requiring serial-to-parallel conversion
• Industrial control interfaces utilizing standard logic families
• Communication modules needing parallel data expansion

Shift Registers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as variations exist between cut tape and full reel quantities. Confirm that the 16-SSOP package dimensions align with the target PCB footprint requirements. Ensure the 4.5 V to 5.5 V supply voltage constraint matches the system power design before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed CMOS performance characteristics. The 74AHCT series offers improved noise immunity compared to standard HC logic while maintaining compatibility with older TTL standards. Consider the 16-SSOP package size for space-constrained surface-mount designs requiring industrial temperature range operation.

Shift Registers Part Context

This part is a member of the Texas Instruments 74AHC and 74AHCT logic families, which are designed for low-power Schottky TTL applications. The AHCT variant specifically bridges the gap between advanced high-speed CMOS technology and traditional TTL logic levels. It serves as a functional equivalent to other industry-standard 8-bit shift registers within the same voltage and speed class.
