74AHCT594DB,112

Shift Registers Overview

The 74AHCT594DB,112 is an octal shift register with output registers and three-state outputs from the Nexperia 74AHCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 60 MHz at 5 V. The device features serial-to-parallel conversion capabilities with independent clock inputs for the shift register and storage register. It utilizes a 20-pin TSSOP package and includes dedicated clear and enable functions for precise data control in digital logic applications.

Shift Registers Feature Summary

• Provides eight-bit serial-in parallel-out data shifting with independent storage register clocks
• Features three-state outputs controlled by separate enable inputs for bus driving
• Includes a master clear input to reset all flip-flops simultaneously

Shift Registers Applications

• Serial-to-parallel data conversion interfaces
• Parallel output expansion for microcontroller systems
• Digital display driver circuits requiring latch functionality

Shift Registers Procurement Notes

Verify the specific suffix 'DB' against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level prior to ordering. Confirm that the 74AHCT logic family compatibility meets the system voltage requirements. Check current production status as component availability may vary.

Shift Registers Selection Notes

Select this component when an octal shift register with three-state outputs is required for 5 V logic systems. Ensure the design accommodates the AHCT input thresholds which are compatible with standard CMOS levels. Verify that the TSSOP-20 package dimensions fit the PCB layout constraints and thermal requirements of the application.

Shift Registers Part Context

This part belongs to the 74AHCT logic family, designed for high-speed operation with CMOS low power dissipation. It is compatible with standard 5 V TTL and CMOS logic families. The device is manufactured by Nexperia USA Inc. and follows JEDEC standards for electrical characteristics and reliability testing.

Shift Registers Replacement Considerations

Check for direct pin-compatible substitutes such as the 74HC594 or 74HCT594 variants from other manufacturers if lead times are critical. Ensure voltage tolerance and speed specifications match the original design requirements.
