HCF4050BEY

Overview

The HCF4050BEY is a hex non-inverting buffer and voltage level converter manufactured by STMicroelectronics. It belongs to the HC4000B CMOS logic family and features five channels in a 16-pin DIP package. The device operates within a supply voltage range of 3 V to 20 V, with a maximum power dissipation of 200 mW. It provides a low-level output current of 19 mA and a quiescent current of 40 nA. The component supports high sink current for driving TTL loads and facilitates high-to-low level logic conversion.

Feature Summary

• Hex non-inverting buffer configuration for signal conditioning
• Capable of high-to-low level logic conversion between different voltage domains
• High sink current capability suitable for driving multiple TTL loads

Applications

• Digital logic circuit buffering
• Voltage level shifting applications
• Signal buffering in prototyping environments

Procurement Notes

Verify the specific suffix 'EY' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the operating temperature range meets system requirements, as industrial variants may differ. Cross-reference the part number with authorized distributors to avoid counterfeit components and validate RoHS compliance status.

Selection Notes

Select this component when a non-inverting hex buffer with robust drive capability is required. It is appropriate for interfacing CMOS outputs with lower voltage TTL inputs. Consider the 16-pin DIP package for through-hole assembly needs. Evaluate the 3 V to 20 V supply range against the target system's power constraints before finalizing the design.

Part Context

This part is part of the HC4000B series, which offers improved speed and noise immunity compared to standard CD4000B devices. The HCF4050B variant specifically provides non-inverting functionality, distinguishing it from the inverting 4049UB counterpart within the same product family.

Replacement Considerations

Compatible substitutes include the SN74HC4050 from Texas Instruments and the MC74HC4050 from ON Semiconductor. Verify that alternative parts maintain the same DIP-16 package and electrical characteristics for direct replacement.
