HEF4094BT,653

Shift Registers Overview

The HEF4094BT,653 is an 8-stage shift-and-store register manufactured by Nexperia. It features a serial-in/serial or parallel-out architecture with separate clocks for the shift and storage registers. The device includes 3-state outputs controlled by an output enable input. Data shifts on LOW-to-HIGH CP transitions, with cascading outputs QS1 and QS2. It operates from 3.0 V to 15.0 V supply voltage. The component supports ambient temperatures from -40 °C to +125 °C and 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 exceeding 2000 V (HBM) and 1000 V (CDM)
• Inputs include clamp diodes for interfacing with voltages in excess of VDD

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '653' against current Nexperia documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required SO16 or TSSOP16 form factor. Confirm that the application environment stays within the specified -40 °C to +125 °C temperature range and 3.0 V to 15.0 V supply limits to maintain performance integrity.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage and 3-state outputs is required. The separate clocks for shift and storage registers allow flexible data handling. Consider the wide supply voltage range and high ESD protection levels for robust industrial applications. Verify pin compatibility if replacing existing designs, noting the specific pin assignments for OE, STR, and CP inputs.

Shift Registers Part Context

The HEF4094B series belongs to Nexperia's CMOS logic family, designed for general-purpose digital applications. The HEF4094BT,653 specifically denotes the version packaged in an SO16 plastic small outline package (SOT109-1). This part is part of a broader line of shift registers offering various packaging options including TSSOP16, catering to different PCB layout requirements.

Shift Registers Replacement Considerations

Check for direct substitutes like HEF4094BTT for TSSOP16 packaging. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
