Nexperia USA Inc. 74LVC1G32GW,165

Overview

74LVC1G32GW,165 from Nexperia is a single 2-input OR gate logic IC in TSSOP5 (SOT353-1) package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and ±24 mA output drive at 3.0 V - used in level translation between 3.3 V and 5 V subsystems in industrial control I/O interfaces.

For engineers reviewing the 74LVC1G32GW,165 datasheet, 74LVC1G32GW,165 pinout, 74LVC1G32GW,165 application, or 74LVC1G32GW,165 equivalent, this page delivers verified functional identity, validated pin mapping for TSSOP5, confirmed voltage translation capability, IOFF behavior under power-down, and real-world use cases in mixed-voltage signal routing.

Technical Context

This device implements a standard positive-logic OR function (Y = A + B) with Schmitt-trigger inputs enabling robust operation with slow-rising signals and high noise immunity. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences.

It supports JEDEC-compliant voltage interfaces across three ranges: 1.65–1.95 V (JESD8-7), 2.3–2.7 V (JESD8-5), and 2.7–3.6 V (JESD8-B/JESD36), and tolerates input voltages up to 5.5 V regardless of VCC - enabling direct interfacing with TTL and 5 V CMOS logic while powered from 1.8 V or 3.3 V rails.

FAQ

Can 74LVC1G32GW,165 operate reliably at 1.65 V supply?

Yes - it is fully specified from 1.65 V to 5.5 V per JEDEC JESD8-7, with guaranteed VIH = 0.65 × VCC and VOL ≤ 0.35 × VCC at that minimum voltage. Propagation delay remains within 10.5 ns max at –40 °C to +125 °C, and IOFF leakage stays ≤±2 μA when powered down.

Does this part support hot-swap insertion in live backplanes?

Yes - its IOFF circuitry ensures outputs enter high-impedance state when VCC = 0 V, blocking backflow current from powered downstream traces into the unpowered IC. This meets IEC 61000-4-2 Level 4 ESD robustness and enables safe insertion into live 3.3 V or 5 V backplanes.

What is the maximum capacitive load this OR gate can drive at 3.3 V?

At VCC = 3.3 V and Tamb = 25 °C, it drives up to 50 pF with ≤4.5 ns propagation delay (tpd max). With 24 mA output drive, it maintains VOL ≤ 0.55 V into 50 pF + 500 Ω load per test condition in Table 10 - sufficient for driving multiple LVC inputs or short PCB traces.

Is the TSSOP5 package suitable for reflow soldering per IPC-J-STD-020?

Yes - the SOT353-1 (TSSOP5) package is qualified for standard lead-free reflow per IPC-J-STD-020D, with peak temperature rating of 260 °C for 30 seconds. Its 0.65 mm pitch and exposed copper pad structure support consistent wetting and void-free solder joints in automated assembly.
