Overview
The HEF4794BT,112 is an 8-stage serial shift register manufactured by Nexperia USA Inc. It operates within a supply voltage range of up to 15V and supports a maximum frequency of 28MHz. The device features surface mount packaging in a 16-SOIC (SOT109) case with 16 terminations. It provides an output current of 40mA per channel and functions reliably across an operating temperature range of -40°C to 125°C.
Feature Summary
- Provides storage latch functionality associated with each stage for data retention
- Supports fully static operation for reliable performance without clocking requirements
- Features 3-state outputs allowing bus line driving capabilities
Applications
- Serial-to-parallel data conversion systems
- Display driver interfaces requiring storage latches
- Industrial control logic circuits
Procurement Notes
Verify the specific suffix '112' against official Nexperia documentation to confirm tape and reel specifications. Ensure the selected variant matches the required 16-SOIC package dimensions and thermal characteristics for your PCB layout. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for your application design.
Selection Notes
Select this component when an 8-bit shift register with independent storage latches is required. The 3-state output capability makes it suitable for multiplexed bus applications. Verify that the 28MHz frequency limit meets your system clock requirements and that the 15V maximum supply voltage aligns with your power rails.
Part Context
This part belongs to the HEF4794B family of dual supply translating shift registers. It is designed for general-purpose digital logic applications requiring serial data input and parallel storage. The device integrates separate clocks for shift and storage operations, providing flexible timing control for complex digital sequences.
Replacement Considerations
Check for direct pin-compatible substitutes such as the HEF4794BT-Q100J for automotive-grade requirements. Verify electrical parameters including propagation delay and output drive strength before substituting with other 8-bit shift registers from different manufacturers.
