HCF4052BEY

Overview

The HCF4052BEY is a differential 4-channel analog multiplexer/demultiplexer fabricated in MOS technology, available in DIP-16 and SOP-16 packages. It features binary address decoding on chip with two control inputs (A, B) and an inhibit input. Key electrical parameters include a typical ON resistance of 125 Ω at VDD - VEE = 15V, matching within 5 Ω, and channel leakage of ±100 pA typ. The device supports digital signal levels from 3 to 20V and analog signals up to 20V peak-to-peak. Quiescent power dissipation is extremely low at 0.2 μW typ. Operating conditions range from -55°C to +125°C.

Feature Summary

• Differential 4-channel architecture allowing simultaneous switching of paired X and Y channels
• Low ON impedance with high linearity for accurate analog signal routing
• Very low OFF leakage current ensuring effective isolation when channels are disabled
• Extremely low quiescent power consumption independent of logic state

Applications

• Time-division measurement systems requiring differential signal selection
• Programmable gain amplifier circuits utilizing matched switch characteristics
• Analog data acquisition systems managing multiple sensor inputs
• Signal routing in test and measurement equipment

Procurement Notes

Verify the specific package variant required for the design, as the HCF4052B family includes both DIP and SOP options. Confirm that the supply voltage configuration meets the operational requirements for the intended analog signal swing. Ensure static handling precautions are observed due to the CMOS construction. Cross-reference the ordering code against the manufacturer's latest documentation to confirm availability and lead times.

Selection Notes

Select this component when differential signal processing is necessary, as it switches paired channels simultaneously unlike single-ended alternatives. Consider the 125 Ω ON resistance and 5 Ω matching tolerance for applications demanding high linearity. Verify that the control logic voltage levels align with the specified VIL and VIH thresholds. Evaluate the thermal derating requirements if operating near the maximum power dissipation limits.

Part Context

The HCF4052B belongs to the standard B-series CMOS device family defined by JEDEC JESD13B specifications. It serves as the differential counterpart to the single-ended HCF4051 (8-channel) and HCF4053 (dual 4-channel). This series is characterized by wide supply voltage ranges and compatibility with standard digital logic families, making it suitable for general-purpose analog switching tasks.

Replacement Considerations

Direct substitutes include the CD4052B from Texas Instruments or the MC14052B from ON Semiconductor. These components share identical pinouts and functional specifications. Verify that any replacement maintains the same package type and temperature rating if environmental constraints are critical.
