Nexperia USA Inc. 74AHC1G32GW,125

Overview

74AHC1G32GW,125 from Nexperia is a single 2-input OR gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS input levels, and guaranteed operation from –40 °C to +125 °C. It serves as a level-translating logic buffer in mixed-voltage I/O interfaces of microcontroller peripheral expansion, sensor signal conditioning, and power management enable logic.

For engineers reviewing the 74AHC1G32GW,125 datasheet, 74AHC1G32GW,125 pinout, 74AHC1G32GW,125 application, or 74AHC1G32GW,125 equivalent, this device is selected for low-power, rail-to-rail compatible OR logic in space-constrained industrial control modules, battery-powered IoT node signal routing, and automotive body electronics where extended temperature range and input overvoltage tolerance are required.

Technical Context

This device implements a single positive-logic OR function (Y = A + B) using advanced CMOS process technology. Its overvoltage-tolerant inputs operate safely at up to 5.5 V regardless of VCC, enabling direct interfacing between 3.3 V logic domains and 5 V legacy peripherals without external level shifters.

Propagation delays are tightly balanced (tPLH ≈ tPHL), with typical values of 4.4 ns at VCC = 3.3 V/CL = 15 pF and 3.2 ns at VCC = 5.0 V/CL = 15 pF. Output drive capability is ±8 mA at VCC = 4.5 V, with symmetrical rise/fall times and low dynamic power dissipation (CPD = 16 pF).

FAQ

Can 74AHC1G32GW,125 be used with a 2.5 V supply?

Yes. The device is fully specified from 2.0 V to 5.5 V, including VIH/VIL thresholds, propagation delay, and output drive at 2.5 V. At VCC = 2.5 V, VIH = 1.75 V min and VOL = 0.36 V max (IO = 4 mA), ensuring reliable interfacing with other 2.5 V logic families.

What is the maximum capacitive load this OR gate can drive reliably?

The device is characterized up to 50 pF (Table 8), with tpd = 7.5 ns max at VCC = 4.5 V. For loads >50 pF, propagation delay increases linearly; total capacitive load should remain ≤100 pF to maintain <15 ns delay and avoid excessive rise/fall time degradation per JEDEC standards.

Does the GND pin (Pin 3) require a dedicated ground plane connection?

Yes. Pin 3 is the sole ground reference for internal logic and output stage. To maintain noise immunity and meet ESD/latch-up specs, it must connect to a low-impedance ground plane via shortest possible trace; splitting or daisy-chaining ground traces degrades performance and risks instability.

Is there a recommended bypass capacitor value and placement for VCC (Pin 5)?

A 100 nF X7R ceramic capacitor is recommended, placed within 5 mm of Pin 5 and connected directly to Pin 3 (GND) with minimal loop area. This suppresses high-frequency supply noise and sustains output drive integrity during fast transitions, especially critical at VCC = 5 V and CL = 50 pF.
