74AHCT594BQ,115

Shift Registers Overview

The Nexperia 74AHCT594BQ,115 is an 8-bit serial-in, parallel-out shift register with an output storage register. It operates on a 4.5 V to 5.5 V supply voltage and utilizes DHVQFN16 packaging (SOT763-1). The device features independent clocks for the shift and storage registers, along with direct overriding clears. It provides balanced propagation delays and high noise immunity.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion capabilities
• Features independent clocks and direct overriding clears for both shift and storage registers
• Includes Schmitt-trigger action on all inputs for enhanced noise immunity
• Offers overvoltage tolerant inputs compatible with 5.5 V systems

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Remote control holding registers
• General-purpose shift register applications requiring TTL input levels

Shift Registers Procurement Notes

Verify the specific ordering suffix 'BQ' corresponds to the DHVQFN16 package configuration required for your design. Confirm that the 74AHCT logic family aligns with your system's TTL input voltage requirements. Ensure thermal management considerations are addressed for the leadless package type during PCB layout.

Shift Registers Selection Notes

Select this component when TTL-compatible input levels are necessary within a CMOS environment. The dual-register architecture allows for simultaneous shifting and stable parallel output presentation. Verify that the operating temperature range meets your environmental specifications before finalizing the design.

Shift Registers Part Context

This part belongs to the 74AHCT series of high-speed Si-gate CMOS devices. It maintains pin compatibility with Low-Power Schottky TTL standards while offering improved switching speeds. The device complies with JEDEC standard No. 7-A for robustness and reliability in digital logic applications.

Shift Registers Replacement Considerations

Direct replacements include other 74AHCT594 variants from Nexperia or equivalent 8-bit shift registers with storage registers from other manufacturers. Ensure any substitute matches the DHVQFN16 footprint and electrical characteristics.
