74AHC594DB,112

Shift Registers Overview

The Nexperia 74AHC594DB,112 is an 8-bit serial-in, parallel-out shift register with an output storage register. It operates on a wide supply voltage range from 2.0 V to 5.5 V and features balanced propagation delays. The device includes independent clocks for the shift and storage registers, as well as direct overriding clears for both sections. It provides Schmitt-trigger action at all inputs and offers high noise immunity. The component is specified for operation across temperatures ranging from -40 °C to +125 °C.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion capabilities with a dedicated storage register.
• Features independent clocking and direct overriding clear functions for both shift and storage stages.
• Includes Schmitt-trigger inputs to ensure tolerance against slow input rise and fall times.

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' against current Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm that the SO16 (SOT109-1) package variant matches your PCB footprint requirements. Check the latest datasheet revision history for any changes to pinning or electrical characteristics before finalizing design integration.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate storage functionality is required. Ensure the system logic levels are compatible with the CMOS input switching levels of the AHC series. Verify that the operating temperature range meets environmental constraints and that the supply voltage remains within the 2.0 V to 5.5 V specification.

Shift Registers Part Context

This part belongs to the 74AHC family of high-speed Si-gate CMOS devices. It is pin-compatible with Low-Power Schottky TTL standards. The device complies with JEDEC standard No. 7-A. It is designed to offer low power dissipation while maintaining high noise immunity and symmetrical output impedance characteristics typical of advanced CMOS logic families.

Shift Registers Replacement Considerations

The 74AHCT594DB,112 serves as a functional replacement with TTL input switching levels instead of CMOS levels. Other package variants such as TSSOP16 or DHVQFN16 may be considered if form factor adjustments are permissible in the design.
