Overview
The HCF4051BEY is a single 8-channel analog multiplexer/demultiplexer fabricated in MOS technology, available in a PDIP-16 package. It features three binary control inputs (A, B, C) and an inhibit input to select one of eight channels. Key electrical parameters include a maximum propagation delay of 60 ns, a maximum on-resistance of 1050 Ohms, and a maximum power dissipation of 500 mW. The device operates within a supply voltage range of 3 V to 20 V and supports an operating temperature range from -40 °C to +85 °C or +125 °C depending on the specific variant documentation.
Feature Summary
- Digitally controlled analog switching with low ON impedance and very low OFF leakage current
- Built-in binary address decoding for channel selection via three control inputs
- Inhibit input terminal functionality to disable all switches when set to high level
- High noise immunity and protection circuits against static discharge
Applications
- Analog signal routing in data acquisition systems
- Audio signal switching applications
- Process control instrumentation
- Industrial automation signal conditioning
Procurement Notes
Verify the specific suffix 'BEY' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected package type matches the PCB footprint requirements. Confirm that the supply voltage and signal levels remain within the specified absolute maximum ratings to prevent device damage during operation.
Selection Notes
Select this component when an 8-channel analog switch is required with CMOS logic compatibility. Consider the HCF series for higher voltage tolerance compared to HC series devices. Verify that the on-resistance and leakage current specifications meet the precision requirements of the analog signal path. Check if the PDIP-16 package is suitable for the assembly process.
Part Context
This part belongs to the HCF4051 family of analog multiplexers produced by STMicroelectronics. It is functionally compatible with the standard 4051 topology but utilizes High-Capacitance CMOS technology. The BEY suffix typically denotes a specific packaging and tape/reel configuration within the PDIP-16 form factor, distinguishing it from other variants like the YM or BY suffixes.
Replacement Considerations
Direct pin-compatible replacements include the M74HC4051 for lower voltage applications, though logic levels differ. Other generic 4051 equivalents from different manufacturers may require verification of on-resistance and leakage current specs. Always cross-reference the specific suffix for package and environmental rating differences.
