74HC4094PW,112

Shift Registers Overview

The Nexperia 74HC4094PW,112 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and features separate clocks for the shift and storage registers. The device includes two serial outputs (QS1 and QS2) for cascading and input clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standard JESD7A and supports operating temperatures from -40 °C to +125 °C.

Shift Registers Feature Summary

• Provides 8-stage shift-and-store bus register functionality with independent clock inputs for shift and storage operations.
• Features 3-state outputs controlled by an output enable input to manage high-impedance OFF-states.
• Includes dual serial outputs (QS1 and QS2) to facilitate cascading across different clock edge speeds.
• Integrates input clamp diodes allowing direct interface to voltages higher than the supply voltage using current limiting resistors.

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 TSSOP16 package (SOT403-1) as defined in the official Nexperia documentation. Confirm that the component meets the required temperature range specifications (-40 °C to +125 °C) for your application environment. Ensure compatibility with the CMOS input levels specified for the 74HC4094 variant.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel output and 3-state capability is required. It is suitable for designs needing separate clocks for shifting and storing data. Consider the TSSOP16 package constraints and the wide supply voltage range (2.0 V to 6.0 V) for flexibility in power supply design.

Shift Registers Part Context

The 74HC4094PW,112 belongs to the Nexperia 74HC/HCT logic family, specifically designed as an 8-stage shift-and-store bus register. It is part of a broader portfolio of CMOS low-power dissipation devices that comply with JEDEC standards. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package, offering a compact solution for surface-mount applications.

Shift Registers Replacement Considerations

Direct replacements include other variants within the 74HC4094 series such as the SO16 (74HC4094D) or SSOP16 (74HC4094DB) packages, provided the pinout and electrical characteristics remain compatible with the existing design.
