HEF4050BT-Q100J

Overview

The HEF4050BT-Q100J is a hex non-inverting buffer from the HEF4050B-Q100 series, qualified to AEC-Q100 Grade 3 for automotive use. It operates within a supply voltage range of 3 V to 15 V and features overvoltage tolerant inputs up to 15 V. The device utilizes CMOS technology with low power dissipation and high noise immunity. It is housed in an SO16 (SOT109-1) package and supports guaranteed fan-out for Standard TTL (2), 74LS (9), and 74L (16). Static characteristics include input leakage currents up to ±1.0 μA at 15 V and supply current up to 120 μA.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 3 standards
• Overvoltage tolerant inputs allowing operation up to 15 V regardless of supply voltage
• High noise immunity and fully static operation capabilities
• 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 with high sink current

Procurement Notes

Verify the specific suffix 'Q100' confirms AEC-Q100 Grade 3 automotive qualification and extended temperature range (-40 °C to +85 °C). Confirm the 'BT' designation corresponds to the SO16 plastic small outline package (SOT109-1). Ensure ordering quantities align with manufacturer packaging specifications.

Selection Notes

Select this component when interfacing between different logic families requiring level shifting or buffering. It is suitable for applications needing high sink current capability to drive multiple TTL loads. Verify that the 15 V input tolerance matches the source signal levels to prevent damage during HIGH-to-LOW transitions.

Part Context

This part belongs to the Nexperia HEF4050B-Q100 family of hex buffers. It is designed as a robust solution for automotive environments where reliability under varying voltage conditions is critical. The device complements other logic ICs by providing signal isolation and voltage translation without inversion.
