Nexperia USA Inc. 74LVC1G32GM,115

Overview

74LVC1G32GM,115 from Nexperia is a single 2-input OR gate logic IC in XSON6 (SOT886) package with 6 terminals, 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 voltage-level translation between 3.3 V and 5 V subsystems in industrial control I/O interfaces.

For engineers reviewing the 74LVC1G32GM,115 datasheet, 74LVC1G32GM,115 pinout, 74LVC1G32GM,115 application, or 74LVC1G32GM,115 equivalent, key selection considerations include input overvoltage tolerance to 5.5 V, guaranteed operation from –40 °C to +125 °C, propagation delay as low as 0.5 ns at 5.5 V, IOFF-enabled backflow current prevention during power sequencing, and compatibility with TTL-level inputs.

Technical Context

This device implements a standard positive-logic OR function (Y = A + B) with Schmitt-trigger inputs enabling robust operation under slow-rising or noisy signal conditions. Its IOFF circuitry actively disables outputs when VCC = 0 V, blocking reverse current flow - critical for hot-swap and mixed-voltage rail sequencing.

It supports dual-voltage interfacing: inputs tolerate up to 5.5 V independent of VCC, allowing direct connection to 5 V sources while powered from 1.65–3.3 V rails. The XSON6 (SOT886) package provides 6 terminals in a 1.0 × 1.45 × 0.5 mm body with no leads and side-wettable flanks for automated optical inspection.

FAQ

Can 74LVC1G32GM,115 operate with VCC = 1.8 V while accepting 5 V inputs?

Yes. The device supports VCC from 1.65 V to 5.5 V and features overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. At VCC = 1.8 V, inputs can safely accept 5 V signals without damage or clamping, enabling seamless 5 V-to-1.8 V level translation without external components.

What is the purpose of the n.c. pin (Pin 5) in the XSON6 package?

Pin 5 is internally not connected and serves no electrical function. It is a structural terminal retained for mechanical symmetry and package manufacturability in the XSON6 (SOT886) layout. No external connection or grounding is required - leaving it floating is the correct implementation per Nexperia's design guidance.

How does IOFF functionality behave during power-down sequences?

When VCC drops to 0 V, the IOFF circuit automatically disables both input and output buffers, limiting I/O leakage to ±2 μA maximum. This prevents backflow current from powered downstream circuits into the unpowered gate, protecting against latch-up and ensuring safe multi-rail power sequencing in complex embedded systems.

Is 74LVC1G32GM,115 suitable for automotive under-hood applications?

Yes - it is fully specified from –40 °C to +125 °C and qualified per JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36. While not AEC-Q100 automotive-qualified, its extended temperature rating, robust ESD protection (HBM >2000 V), and IOFF safety features make it suitable for non-safety-critical under-hood functions like HVAC control or lighting supervision where customer validation is performed.
