74HC595D,112

Shift Registers Overview

The Nexperia 74HC595D,112 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates on a wide supply voltage range from 2.0 V to 6.0 V. The device features separate clocks for the shift and storage registers, a serial input (DS), and a serial output (Q7S) for cascading. An asynchronous reset (MR) input clears the shift register. Data shifts on LOW-to-HIGH transitions of the SHCP input, while data transfers to the storage register on STCP transitions. Outputs are enabled when OE is LOW.

Shift Registers Feature Summary

• Provides 8-bit serial input capability with flexible serial or parallel output options.
• Includes a storage register with 3-state outputs controlled by an active-low enable signal.
• Features a shift register with direct clear functionality via an asynchronous master reset input.
• Offers high noise immunity and low power dissipation characteristics typical of CMOS technology.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO16 plastic small outline package (SOT109-1). Confirm the component status against current Nexperia documentation, as availability may vary. Ensure compatibility with the required operating temperature range of -40 °C to +125 °C for your specific design environment before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and shift clocking is required. It is suitable for designs needing 3-state outputs to manage bus contention. Verify that the CMOS input levels meet the system logic requirements, distinguishing it from the HCT variant which supports TTL levels. Ensure the SO16 package fits the available PCB footprint constraints.

Shift Registers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally equivalent to the standard 74HC595 type number but specified in the SO16 package format designated by the 'D' suffix. The '112' suffix indicates the specific tape and reel or tube packaging configuration provided by the manufacturer.

Shift Registers Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74HC595 variants in SOIC-16 packages. Cross-reference with 74HCT595 if TTL input levels are required instead of CMOS levels. Verify that any substitute maintains the same 3-state output capability and package dimensions.
