Nexperia USA Inc. 74VHC08D-Q100J

Overview

74VHC08D-Q100 from Nexperia is a quad 2-input AND gate IC designed for automotive signal logic gating in powertrain control units, body electronics, and ADAS sensor interface modules. It operates across -40 °C to +125 °C, supports 2.0–5.5 V supply, delivers ≤7.5 ns propagation delay at 5 V/50 pF, and features Schmitt-trigger inputs with TTL- and CMOS-compatible input thresholds.

For engineers reviewing the 74VHC08D-Q100 datasheet, 74VHC08D-Q100 pinout, 74VHC08D-Q100 application, or 74VHC08D-Q100 equivalent, this page provides verified automotive-grade logic timing, SO14 package mechanical data, AEC-Q100 Grade 1 qualification evidence, and direct substitution guidance against 74VHCT08D-Q100 and SN74LVC08A-Q1.

Technical Context

This device implements four independent 2-input AND gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC JESD7-A and AEC-Q100 Grade 1. Its input structure accepts voltages up to 7.0 V regardless of VCC, and all inputs include Schmitt-trigger action for noise immunity on slow-rising signals.

The logic function follows standard Boolean AND behavior: output is HIGH only when both inputs are HIGH; otherwise, output is LOW. Propagation delays are balanced between rising and falling edges (tPLH ≈ tPHL), and output drive capability is ±8.0 mA at VCC = 4.5 V with guaranteed VOH ≥ 3.7 V and VOL ≤ 0.55 V over full temperature range.

FAQ

Is 74VHC08D-Q100 pin-compatible with standard 74LS08?

Yes, it is fully pin-compatible with 74LS08 and other LSTTL quad AND gates in SO14 packages. The pin numbering, terminal functions, and physical dimensions match SOT108-1 exactly, enabling direct PCB-level replacement without layout changes. Electrical compatibility is maintained through identical logic thresholds and output drive strength at 5 V operation.

What is the maximum input voltage rating for 74VHC08D-Q100?

The absolute maximum input voltage is +7.0 V, referenced to GND, regardless of VCC level. This overvoltage tolerance allows safe interfacing with 12 V sensor outputs or legacy 5 V TTL systems without external clamping diodes. Operation above VCC is permitted only if input current remains within ±20 mA limits per IEC 60134.

Does 74VHC08D-Q100 support mixed-voltage domain interfacing?

No - it does not perform level translation. While inputs tolerate up to 7.0 V, the output swing is rail-to-rail (0 V to VCC), so driving a 3.3 V device from a 5 V-powered 74VHC08D-Q100 requires an external resistor divider or buffer. Its Schmitt-trigger inputs improve noise margin but do not convert logic thresholds across voltage domains.

How is thermal performance affected in SO14 package at +125 °C ambient?

In SO14 (SOT108-1), total power dissipation derates linearly at 10.1 mW/K above 100 °C. At +125 °C ambient, Ptot drops to 247 mW from the 500 mW rated value. This requires limiting switching frequency or load capacitance in high-temperature zones; typical automotive use at <1 MHz with 15–30 pF loads stays well within thermal limits.
