Nexperia USA Inc. 74LVC32APW-Q100J

Overview

74LVC32APW-Q100 from Nexperia is an automotive-grade quad 2-input OR gate in TSSOP14 package, operating from 1.2 V to 3.6 V supply with overvoltage-tolerant inputs up to 5.5 V, Schmitt-trigger inputs for noise immunity, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It enables level translation between 3.3 V and 5 V logic domains in body control modules and powertrain interface circuits.

For engineers reviewing the 74LVC32APW-Q100 datasheet, 74LVC32APW-Q100 pinout, 74LVC32APW-Q100 application, or 74LVC32APW-Q100 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V (typ. 2.2 ns), output drive strength (±24 mA), Schmitt-trigger hysteresis, and automotive temperature compliance.

Technical Context

This device implements four independent OR logic functions (A + B = Y) with CMOS architecture and rail-to-rail output swing. Each input features Schmitt-trigger action with hysteresis ≥0.3 V at VCC = 3.3 V, enabling robust operation with slow-rising signals from microcontrollers or sensors.

It supports mixed-voltage interfacing: inputs accept 0–5.5 V regardless of VCC (1.2–3.6 V), allowing direct connection to legacy 5 V peripherals while powered from modern 3.3 V or 1.8 V rails. Propagation delay is specified down to 1.0 ns (min) at VCC = 3.0–3.6 V, with output skew ≤1.5 ns across gates.

FAQ

Is the 74LVC32APW-Q100 pin-compatible with standard 74LVC32A variants?

Yes - it shares identical pinout (SOT402-1/TSSOP14) and logic function with non-automotive 74LVC32A parts like SN74LVC32APWR. All 14 pins map identically: inputs (1A–4B), outputs (1Y–4Y), GND (pin 7), and VCC (pin 14). No PCB redesign is needed when upgrading to AEC-Q100 qualification.

Can inputs be driven by 5 V TTL while VCC is at 1.8 V?

Yes - inputs tolerate up to 5.5 V regardless of VCC (1.2–3.6 V), satisfying JEDEC JESD8-5A (2.3–2.7 V) and JESD8-C (2.7–3.6 V) standards. At VCC = 1.8 V, VIH remains 0.65 × VCC = 1.17 V and VIL is 0.35 × VCC = 0.63 V, ensuring reliable recognition of 5 V TTL HIGH/LOW levels.

What is the maximum clock frequency supported for repetitive OR operations?

The device is not a clocked sequential circuit but a combinational gate. Its usable toggle rate is limited by propagation delay (tpd ≤ 5.0 ns max at VCC = 3.0–3.6 V) and output load. With 50 pF load and 3.3 V supply, maximum reliable data rate is ~100 MHz for clean pulse trains, verified per Table 8 test conditions using 500 Ω termination.

Does the TSSOP14 package require special reflow or inspection processes?

No - SOT402-1 conforms to JEDEC MO-153 standards and is compatible with standard leaded SMT reflow profiles (peak 260 °C). Unlike DHVQFN variants, it does not require side-wettable flank inspection; standard AOI suffices for solder joint quality verification on all 14 gull-wing leads.
