Nexperia USA Inc. 74HC08BQ-Q100,115

Overview

74HC08BQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in DHVQFN14 package, operating from 2.0 V to 6.0 V supply, specified over −40 °C to +125 °C, with CMOS-level inputs, 15 ns typical propagation delay at 4.5 V, and AEC-Q100 Grade 1 qualification for engine control and body electronics.

For engineers reviewing the 74HC08BQ-Q100 datasheet, 74HC08BQ-Q100 pinout, 74HC08BQ-Q100 application, or 74HC08BQ-Q100 equivalent, key selection criteria include input logic compatibility (CMOS), thermal-enhanced QFN packaging, automotive temperature range compliance, and dynamic timing performance under 50 pF load.

Technical Context

This device implements four independent 2-input AND logic functions using silicon-gate CMOS technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds referenced to VCC.

It supports dual logic families: 74HC08BQ-Q100 uses CMOS-level input thresholds (VIH = 3.15 V min at VCC = 4.5 V), while its HCT variant accepts TTL-compatible inputs (VIH = 2.0 V min). Both share identical pinout, package, and AEC-Q100 qualification.

Key Specifications

Pinout & Package

DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, side-wettable flanks for AOI-compatible solder joint inspection, exposed thermal pad (non-electrical, optional GND connection).

FAQ

Is the exposed thermal pad on the DHVQFN14 package electrically connected?

No-the thermal pad (Pin 1 index area) is not electrically tied to any internal node. Per datasheet note, it has no electrical or mechanical requirement to be soldered; if connected, it must remain floating or be tied to GND to avoid parasitic coupling or thermal stress.

Can 74HC08BQ-Q100 interface directly with 12 V sensors?

Yes-its integrated input clamp diodes allow safe connection to voltages up to VCC + 0.5 V when used with appropriate series current-limiting resistors (e.g., 10 kΩ for 12 V → 5 V interface), eliminating need for external protection diodes.

What is the maximum output current per pin at 125 °C?

At −40 °C to +125 °C, the device supports ±4.0 mA DC output current per Y-pin (e.g., Pin 3, 6, 8, 11) with VOH ≥ 3.7 V and VOL ≤ 0.4 V at VCC = 4.5 V, verified per Table 6 static characteristics.

Does this part support mixed-voltage domain operation?

No-it operates from a single VCC rail (2.0–6.0 V); inputs and outputs are referenced solely to that supply. For mixed-voltage systems (e.g., 3.3 V logic driving 5 V peripherals), external level-shifting circuitry is required.
