HEF4050BT,653

Overview

The HEF4050BT,653 is a hex non-inverting buffer from the Nexperia HEF4000 logic family. It operates on a supply voltage range of 3 V to 15 V and features overvoltage tolerant inputs capable of handling up to 15.0 V. The device provides six independent channels in an SO16 (SOT109-1) package. Static characteristics include low power dissipation and high noise immunity. Dynamic performance at 25 °C includes propagation delays ranging from 15 ns to 70 ns depending on load capacitance and supply voltage.

Feature Summary

• Overvoltage tolerant inputs allow safe interfacing with higher voltage logic levels without damage.
• Standardized symmetrical output characteristics ensure consistent HIGH and LOW level performance.
• Fully static operation guarantees stable states without continuous current draw when idle.
• Complies with JEDEC standard JESD 13-B for robustness and interchangeability.

Applications

• LOCMOS to DTL/TTL converter
• HIGH sink current driving for two TTL loads
• HIGH-to-LOW level logic conversion

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature rating. Confirm that the component meets RoHS directives if environmental compliance is mandatory for the assembly process. Ensure input voltage limits are respected during system design to prevent exceeding absolute maximum ratings.

Selection Notes

Select this component when designing circuits requiring level shifting between different logic families or voltage domains. The wide supply voltage range supports various industrial and commercial applications. Verify that the package type aligns with the available PCB footprint and soldering capabilities.
