HEF4050BP,652

Overview

The HEF4050BP,652 is a hex non-inverting buffer featuring overvoltage tolerant inputs rated up to 15.0 V. It operates within a supply voltage range of 3.0 V to 15.0 V and supports an input voltage up to 15 V. The device provides standardized symmetrical output characteristics with high noise immunity and low power dissipation. Propagation delays vary by voltage: at 5 V, tPHL is 70 ns max and tPLH is 110 ns max; at 15 V, tPHL is 30 ns max and tPLH is 40 ns max. It complies with JEDEC standard JESD 13-B.

Feature Summary

• Hex non-inverting buffer configuration with six independent channels
• Overvoltage tolerant inputs allowing operation with signals up to 15.0 V
• High noise immunity and fully static operation for reliable performance
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• LOCMOS to DTL/TTL converter
• HIGH-to-LOW level logic conversion
• Driving two TTL loads

Procurement Notes

Verify the package type matches the specific suffix requirements, as the HEF4050B series includes both SO16 surface-mount and older DIP variants. Confirm that the ordering suffix corresponds to the desired packaging format. Ensure compatibility with the intended operating temperature range of -40 °C to +85 °C. Check for any recent revision updates in the product data sheet before finalizing procurement specifications.

Selection Notes

Select this component when interfacing between different logic families requiring level shifting from higher to lower voltages. The overvoltage tolerance simplifies connections where input signals exceed the supply voltage of the receiving circuit. Consider the propagation delay specifications relative to the system clock speed. Verify that the load capacitance requirements align with the dynamic performance limits defined in the datasheet.

Part Context

This part belongs to the HEF4050B family of hex buffers manufactured by Nexperia. The 'BP' suffix typically denotes a PDIP package variant, although current documentation primarily details the SO16 version. The device is part of the broader 4000-series CMOS logic family, designed for general-purpose digital applications requiring robust signal buffering and translation capabilities.

Replacement Considerations

HEF4050BT,652 is a documented alternative offering the same logical function in an SO16 package.
