Nexperia USA Inc. 74LVC32APW,118

Overview

74LVC32APW,118 from Nexperia is a quad 2-input OR gate logic IC 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 guaranteed operation from −40 °C to +125 °C. It enables level translation between 3.3 V and 5 V domains in mixed-voltage digital systems such as industrial I/O controllers and FPGA interface buffers.

For engineers reviewing the 74LVC32APW,118 datasheet, 74LVC32APW,118 pinout, 74LVC32APW,118 application, or 74LVC32APW,118 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V (typ. 2.2 ns), output drive strength (±24 mA), thermal performance in TSSOP14, and JEDEC-compliant ESD robustness (HBM >2000 V).

Technical Context

This device implements four independent OR logic functions (A + B → Y) with Schmitt-trigger inputs that accept slow-rising signals and reject noise below hysteresis thresholds. Each gate operates with rail-to-rail CMOS-compatible output swing and supports direct interfacing to TTL-level drivers.

It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), ensuring interoperability across legacy and modern low-voltage logic families. Input clamping allows safe 5 V signal injection while powered from 3.3 V or lower.

FAQ

Can 74LVC32APW,118 safely interface a 5 V sensor output to a 3.3 V microcontroller?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC voltage, enabling direct connection of 5 V signals to the 74LVC32APW,118 while powered from 3.3 V. No external resistors or level shifters are needed, and Schmitt-trigger inputs suppress noise on the sensor line.

What is the maximum capacitive load this device can drive at 3.3 V supply?

At VCC = 3.3 V, the 74LVC32APW,118 drives up to 50 pF with guaranteed 5.0 ns max propagation delay (−40 °C to +125 °C). For heavier loads, derate timing margins using CPD = 11.0 pF and dynamic power formula PD = CPD × VCC² × fi × N.

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

No. Unused inputs may be tied directly to VCC or GND. Due to Schmitt-trigger inputs and CMOS structure, floating inputs are electrically unstable and must be avoided; internal leakage is <±0.1 μA, so hard-wiring is preferred over high-value resistors.

Is thermal performance validated for continuous operation at +125 °C ambient?

Yes. The TSSOP14 package (SOT402-1) is characterized for full functionality at −40 °C to +125 °C. Total power dissipation is derated linearly at 7.3 mW/K above +81 °C, limiting Ptot to ~340 mW at +125 °C ambient under typical switching conditions.
