74HC4094DB,112

Shift Registers Overview

The Nexperia 74HC4094DB,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 supports ambient temperatures from -40 °C to +125 °C. The device features separate clocks for the shift and storage registers, along with serial outputs (QS1 and QS2) for cascading. Inputs include clamp diodes to interface with voltages exceeding VCC.

Shift Registers Feature Summary

• Provides 8-stage shift-and-store bus register functionality with 3-state outputs
• Features separate clocks for shift and storage registers to enable independent data handling
• Includes serial outputs (QS1 and QS2) to facilitate cascading operations
• Integrates input clamp diodes for interfacing with voltages in excess of VCC

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify that the ordering suffix '112' corresponds to the SSOP16 package (SOT338-1) as documented in the product data sheet revision history. Confirm the specific logic family variant (HC vs HCT) required for the application, as datasheet specifications differ between them. Ensure compatibility with the specified temperature range and voltage limits before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel output and 3-state capability is required. The SSOP16 package suits space-constrained designs. Verify input levels match the system logic (CMOS for HC, TTL for HCT). Consider the separate clock inputs for shift and storage registers if independent data latching is necessary for the design architecture.

Shift Registers Part Context

The 74HC4094DB,112 belongs to the Nexperia 74HC/HCT4094 series of 8-stage shift-and-store bus registers. It is part of a broader portfolio of CMOS logic devices designed for general-purpose digital applications. The DB suffix indicates the SSOP16 plastic shrink small outline package, offering a compact footprint for surface-mount assembly.

Shift Registers Replacement Considerations

Nexperia datasheet revision v.9 explicitly states that type number 74HC4094DB was removed from the active product list. Designers should verify current availability and consider alternative packages such as SO16 (D) or TSSOP16 (PW) which remain listed in the ordering information table.
