HEF4094BT,652

Shift Registers Overview

The HEF4094BT,652 is an 8-bit serial-in/serial or parallel-out shift register with a storage register and 3-state outputs. It operates from a supply voltage of 3.0 V to 15.0 V. The device features separate clocks for the shift and storage registers. Data shifts on LOW-to-HIGH transitions of the CP input. Serial outputs QS1 and QS2 enable cascading. Inputs include clamp diodes for interfacing voltages exceeding VDD. It complies with JEDEC standard JESD 13-B.

Shift Registers Feature Summary

• Fully static operation with CMOS low power dissipation
• High noise immunity and standardized symmetrical output characteristics
• ESD protection exceeds 2000 V (HBM) and 1000 V (CDM)
• Specified for ambient temperatures from -40 °C to +125 °C

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register
• Digitally controlled equipment

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package and temperature grade alignment. Confirm that the HEF4094BT,652 designation corresponds to the SO16 plastic small outline package variant as detailed in the official product data sheet. Cross-reference part numbers with authorized distributors to validate authenticity and traceability before procurement.

Shift Registers Selection Notes

Select this component when an 8-stage shift-and-store register with 3-state outputs is required. Ensure the design accommodates the wide supply voltage range of 3.0 V to 15.0 V. Verify that the operating environment falls within the specified -40 °C to +125 °C temperature range. Consider the separate clock inputs for shift and storage operations when designing the control logic interface.

Shift Registers Part Context

The HEF4094B belongs to the Nexperia HEF4000 series of CMOS logic devices. This family provides fully static operation and high noise immunity. The HEF4094B specifically functions as an 8-bit shift register with a storage latch. It is designed for general-purpose digital applications requiring serial-to-parallel conversion capabilities within standard industrial temperature ranges.
