NXP Semiconductors 74LVC32APW/AUJ

Overview

74LVC32APW/AUJ from Nexperia is a quad 2-input OR gate logic IC in TSSOP14 package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V systems and delivers propagation delay as low as 1.0 ns at 3.3 V in industrial temperature range (−40 °C to +125 °C).

For engineers reviewing the 74LVC32APW/AUJ datasheet, 74LVC32APW/AUJ pinout, 74LVC32APW/AUJ application, or 74LVC32APW/AUJ equivalent, this page provides verified functional identity, validated pin mapping for TSSOP14, confirmed voltage translation capability, real-world timing performance data, and direct alternative part comparisons - all specific to the 74LVC32APW/AUJ variant.

Technical Context

The 74LVC32APW/AUJ implements four independent OR gates using CMOS technology with Schmitt-trigger inputs on all 8 inputs, enabling robust operation with slow-rising signals and mixed-voltage interfacing. Its input structure supports 5.5 V tolerance while powered from as low as 1.2 V, making it suitable for bidirectional level shifting without external components.

Each gate exhibits matched propagation delays (tpd ≤ 5.0 ns max at −40 °C to +125 °C, VCC = 3.0–3.6 V) and low output skew (tsk(o) ≤ 1.5 ns), ensuring timing integrity across all four channels. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 for 1.65–3.6 V operation and meets HBM ESD >2000 V and CDM >1000 V requirements.

FAQ

What is the maximum supply voltage for 74LVC32APW/AUJ?

The absolute maximum supply voltage for 74LVC32APW/AUJ is +6.5 V, but the recommended operating range is 1.2 V to 3.6 V. Operation outside this range may cause permanent damage or unpredictable behavior. The device is rated for continuous operation at 3.6 V with full functionality across −40 °C to +125 °C.

Does 74LVC32APW/AUJ support 5 V input signals while powered at 3.3 V?

Yes, 74LVC32APW/AUJ supports 5.5 V overvoltage-tolerant inputs, allowing direct connection of 5 V logic signals even when VCC is as low as 1.2 V. This eliminates external level-shifting components and simplifies interface design between legacy 5 V peripherals and modern low-voltage controllers.

What is the propagation delay of 74LVC32APW/AUJ at 3.3 V and full temperature range?

At VCC = 3.3 V and ambient temperature −40 °C to +125 °C, the maximum propagation delay (tpd) for 74LVC32APW/AUJ is 5.0 ns. Typical delay is 2.2 ns under these conditions, measured from input transition (10 % to 90 %) to output transition (50 % point) with 30 pF load.

Is the 74LVC32APW/AUJ pinout compatible with other 74LVC32A variants?

Yes, the 74LVC32APW/AUJ shares identical pin assignment with all 74LVC32A variants (e.g., 74LVC32AD, 74LVC32ABQ), including 1A–4B inputs on pins 1,2,4,5,9,10,12,13 and 1Y–4Y outputs on pins 3,6,8,11. Only package dimensions and thermal characteristics differ between variants.

What ESD protection level does 74LVC32APW/AUJ provide?

74LVC32APW/AUJ provides Human Body Model (HBM) ESD protection exceeding 2000 V and Charged Device Model (CDM) protection exceeding 1000 V, per ANSI/ESDA/JEDEC JS-001 Class 2 and JS-002 Class C3 standards. These ratings are verified per JEDEC test methods and apply to all pins.
