Nexperia USA Inc. 74LVC1G27GM,132

Overview

74LVC1G27GM,132 from Nexperia is a single 3-input NOR 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 domains in portable interface circuits.

For engineers reviewing the 74LVC1G27GM,132 datasheet, 74LVC1G27GM,132 pinout, 74LVC1G27GM,132 application, or 74LVC1G27GM,132 equivalent, key selection criteria include input voltage tolerance up to 5 V, propagation delay as low as 1.0 ns at 5.5 V, IOFF-enabled backflow prevention during power sequencing, and operation across –40 °C to +125 °C industrial temperature range.

Technical Context

This device implements a single 3-input NOR Boolean function with true output polarity and no internal inversion. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow-rising signals from microcontrollers or sensors.

The IOFF circuit actively disables outputs when VCC = 0 V, limiting off-state leakage to ±2 μA while allowing safe I/O floating in mixed-voltage hot-swap systems. Input thresholds comply with JEDEC standards JESD8-7 through JESD36 across 1.65–5.5 V supply range.

FAQ

Can 74LVC1G27GM,132 operate with VCC = 1.8 V while accepting 3.3 V inputs?

Yes. The device complies with JEDEC JESD8-7 for 1.65–1.95 V operation and features 5 V-tolerant inputs - inputs accept up to 5.5 V regardless of VCC level. At VCC = 1.8 V, VIH is 0.65 × VCC ≈ 1.17 V and VIL is 0.35 × VCC ≈ 0.63 V, ensuring reliable recognition of 3.3 V logic highs.

Does the IOFF feature require external circuitry to function?

No. IOFF is fully internal and automatic: when VCC drops to 0 V, the output transistors are disabled without external bias or control signals. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to any I/O pin, eliminating need for external isolation switches or series resistors.

What is the maximum capacitive load this device can drive reliably?

Based on dynamic characteristics and CPD = 12 pF, the device maintains specified tpd up to 50 pF load capacitance at VCC ≥ 3.0 V. For loads exceeding 50 pF, propagation delay increases linearly; verified operation up to 100 pF is achievable with <10% tpd degradation at 3.3 V, provided trace impedance and layout minimize ringing.

How does Schmitt-trigger action improve noise immunity in real-world layouts?

Schmitt-trigger inputs provide ~0.3 V hysteresis at 3.3 V supply, meaning the rising threshold is ~1.8 V and falling threshold is ~1.5 V. This prevents multiple toggles from noise spikes <0.3 V peak-to-peak on PCB traces longer than 5 cm, especially beneficial for pushbutton debouncing or open-collector sensor outputs without external RC filtering.
