Nexperia USA Inc. 74LVC32ADB-Q100J

Overview

74LVC32ADB-Q100 from Nexperia is a quad 2-input OR gate 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, overvoltage-tolerant inputs up to 5.5 V, and Schmitt-trigger inputs enabling robust noise immunity in mixed-voltage systems. It serves as a level-translating logic combiner in body control modules and infotainment power sequencing.

For engineers reviewing the 74LVC32ADB-Q100 datasheet, 74LVC32ADB-Q100 pinout, 74LVC32ADB-Q100 application, or 74LVC32ADB-Q100 equivalent, key selection criteria include its 5.5 V input tolerance, −40 °C to +125 °C automotive qualification, 1.2 V minimum V_CC, propagation delay down to 1.0 ns at 3.3 V, and DHVQFN14 package with side-wettable flanks for AOI-compatible solder joint inspection.

Technical Context

This device implements four independent 2-input OR gates in a single monolithic CMOS structure, each with Schmitt-trigger inputs to tolerate slow-rising signals and reject noise on low-slew-rate buses. All inputs accept 3.3 V or 5 V logic levels while powered from 1.2–3.6 V, enabling bidirectional voltage translation without external components.

Its static and dynamic behavior is specified across two temperature ranges (−40 °C to +85 °C and −40 °C to +125 °C), with guaranteed VOL ≤ 0.55 V at 24 mA sink and VOH ≥ 2.2 V at 24 mA source under 3.0 V operation, and t_pd ≤ 5.0 ns max over full temperature and voltage range.

FAQ

Is 74LVC32ADB-Q100 pin-compatible with standard 74LVC32A devices?

Yes - the 74LVC32ADB-Q100 shares identical logic function, pin numbering, and electrical behavior with other 74LVC32A variants. Its DHVQFN14 (SOT762-1) footprint differs mechanically from SO14 or TSSOP14, but the terminal mapping matches the functional pinout: pins 1–14 correspond to 1A, V_CC, 1B, 4B, 1Y, 4A, 2A, 4Y, 2B, 3B, 2Y, 3A, GND, 3Y as defined in the datasheet.

What is the maximum input frequency supported by this OR gate?

The device does not specify a maximum clock frequency, as it is a combinational logic gate-not a clocked device. Its usable switching rate is determined by propagation delay and load capacitance. With 50 pF load and 3.3 V supply, t_pd ≤ 3.8 ns (typical), supporting clean signal combining up to ~100 MHz for low-capacitance routing; actual bandwidth depends on PCB layout and termination.

Can 74LVC32ADB-Q100 drive LEDs directly?

Yes - each output can sink or source up to ±24 mA. At V_CC = 3.3 V and I_O = 10 mA, VOL is guaranteed ≤ 0.4 V and VOH ≥ 2.7 V, providing sufficient margin to drive standard 2 mA indicator LEDs with appropriate current-limiting resistors. Thermal limits must be observed when driving multiple outputs simultaneously.

Does this part require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied to V_CC or GND directly. Due to Schmitt-trigger inputs and CMOS structure, floating inputs are strictly prohibited and will cause excessive current draw and logic instability. The datasheet explicitly requires all inputs to be actively driven or terminated to a valid logic level.
