74HCT4094PWJ

Shift Registers Overview

The Nexperia 74HCT4094PWJ 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 4.5 V to 5.5 V. The device features separate clocks for the shift and storage registers, allowing independent control. Data shifts on LOW-to-HIGH transitions of the clock input (CP). It includes two serial outputs (QS1 and QS2) for cascading and clamp diodes on inputs. The component is specified for operation from -40 °C to +125 °C.

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
• Includes dual serial outputs (QS1 and QS2) for cascading applications
• Inputs include clamp diodes for interfacing voltages exceeding VCC

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm package variant details. Ensure the selected component matches the required TSSOP16 form factor and HCT logic family specifications. Confirm that the temperature range and electrical characteristics align with the target application environment before finalizing procurement.

Shift Registers Selection Notes

Select this component when TTL-compatible input levels are required for 5 V systems. The 74HCT series ensures compatibility with standard TTL logic families while offering CMOS low power dissipation. Consider the 3-state output capability if bus sharing is necessary in the circuit design. Verify that the operating temperature range meets the environmental requirements of the deployment scenario.

Shift Registers Part Context

This part belongs to the 74HCT4094 series, which is an 8-bit shift-and-store bus register. It is part of Nexperia's broader portfolio of logic integrated circuits designed for general-purpose digital applications. The PWJ designation indicates a specific packaging and handling configuration within the TSSOP16 family.

Shift Registers Replacement Considerations

Direct pin-to-pin replacements may include other manufacturers' 74HCT4094 variants in TSSOP16 packages. Verify electrical parameters such as propagation delay and supply voltage ranges to ensure functional equivalence. Cross-reference with Nexperia's official substitution guides for confirmed compatible alternatives.
