Nexperia USA Inc. 74LVC1G32GM,132

Overview

74LVC1G32GM,132 from Nexperia is a single 2-input OR gate logic IC in XSON6 (SOT886) 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 I/O controllers.

For engineers reviewing the 74LVC1G32GM,132 datasheet, 74LVC1G32GM,132 pinout, 74LVC1G32GM,132 application, or 74LVC1G32GM,132 equivalent, key selection criteria 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, and compatibility with TTL-level signals in mixed-voltage digital interfaces.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B) with Schmitt-trigger inputs that accept slow-rising/falling waveforms without oscillation. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

The logic core uses CMOS technology with rail-to-rail output swing and supports direct interfacing across 1.65–5.5 V supply domains. Input thresholds are voltage-ratio-based (e.g., VIH = 0.7 × VCC at 4.5–5.5 V), enabling robust level translation without external biasing.

FAQ

Can 74LVC1G32GM,132 operate with 1.8 V supply and interface to 5 V inputs?

Yes. The device is fully specified from 1.65 V to 5.5 V supply and features overvoltage-tolerant inputs rated to 5.5 V - allowing safe connection of 5 V signals while powered from 1.8 V without external components. This is confirmed in Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values) of the datasheet.

What is the function of the n.c. pin on the XSON6 package?

The n.c. (no connect) pin on the SOT886 package is internally unconnected and must remain floating - it must not be tied to VCC, GND, or any other net. This is explicitly stated in Table 3 (Pin Description) and verified in the pinning diagrams (Fig. 3, aaa-035733). Connecting it may cause unpredictable behavior or damage.

Does 74LVC1G32GM,132 support hot-swap or partial power-down operation?

Yes. It incorporates an IOFF circuit that disables outputs when VCC = 0 V, limiting power-off leakage current to ±2 μA maximum (Table 7). This prevents damaging back-current flow through the device during live insertion or multi-rail sequencing - a feature validated per JEDEC JESD78 and documented in Section 1 (General description).

How does Schmitt-trigger input action benefit system design?

Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V depending on VCC), making the gate tolerant of slow-rising/falling edges and noise on input lines. This eliminates need for external RC filtering or software debouncing in applications like mechanical switch interfaces or analog comparator outputs - directly improving reliability in electrically noisy industrial environments.
