Nexperia USA Inc. 74LVC32ABQ-Q100X

Overview

74LVC32ABQ-Q100 from Nexperia is a quad 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage 1.2 V to 3.6 V and overvoltage-tolerant inputs up to 5.5 V. It features Schmitt-trigger inputs for noise immunity, supports mixed 3.3 V/5 V logic translation, and delivers propagation delay as low as 1.0 ns at 3.3 V in automotive environments.

For engineers reviewing the 74LVC32ABQ-Q100 datasheet, 74LVC32ABQ-Q100 pinout, 74LVC32ABQ-Q100 application, or 74LVC32ABQ-Q100 equivalent, key selection criteria include its AEC-Q100 qualification, DHVQFN14 package with side-wettable flanks for AOI, input overvoltage tolerance, Schmitt-trigger input hysteresis, and guaranteed operation across full automotive temperature range.

Technical Context

This device implements four independent 2-input OR logic functions in a single monolithic CMOS structure. Each gate exhibits Schmitt-trigger action at both inputs, providing hysteresis of typically 0.3 V to 0.5 V depending on VCC, enabling robust operation with slow-rising or noisy signals.

It operates across a wide VCC range (1.2 V–3.6 V) while maintaining TTL-compatible input thresholds and 5.5 V overvoltage-tolerant inputs - allowing direct interfacing with legacy 5 V systems without level shifters. Output drive capability is ±24 mA at 3.0 V, supporting standard LVC fanout requirements.

FAQ

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

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

Can 74LVC32ABQ-Q100 interface directly with 5 V TTL outputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC level (1.2–3.6 V), and VIH/VIL thresholds comply with JEDEC JESD8-7A/5A/C standards. This enables direct connection to 5 V TTL without level shifters, preserving signal integrity and reducing BOM count.

What is the maximum output current per pin, and how does it vary with VCC?

The device supports ±24 mA per output at VCC = 3.0 V, with VOH ≥ 2.2 V and VOL ≤ 0.55 V under that load. At lower VCC (e.g., 1.65 V), output drive reduces to ±4 mA (VOH ≥ 1.2 V, VOL ≤ 0.45 V), as specified in Table 6 of the datasheet.

Does the Schmitt-trigger input behavior affect propagation delay specifications?

Yes - Schmitt-trigger hysteresis increases effective input threshold transition width, which slightly extends measured tPLH/tPHL compared to non-hysteresis gates. However, the datasheet's tpd values (e.g., 1.0–5.0 ns) already reflect worst-case delays under Schmitt-trigger operation across temperature and voltage.
