Nexperia USA Inc. 74AHC1G02GW,125

Overview

74AHC1G02GW,125 from Nexperia is a single 2-input CMOS NOR 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 and specified for -40 °C to +125 °C industrial temperature range. It delivers symmetrical output impedance, balanced propagation delays (typ. 3.2 ns at 5 V, 15 pF), and supports mixed-voltage logic translation in embedded control interfaces.

For engineers reviewing the 74AHC1G02GW,125 datasheet, 74AHC1G02GW,125 pinout, 74AHC1G02GW,125 application, or 74AHC1G02GW,125 equivalent, this device serves as a compact, low-power combinational logic element for level-shifting, enable/disable gating, and noise-immune signal conditioning in space-constrained industrial and automotive-adjacent systems.

Technical Context

This NOR gate implements standard positive-logic Boolean function Y = NOT(A OR B), with CMOS-level input thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max). Its overvoltage-tolerant inputs allow direct interfacing between 3.3 V logic domains and 5 V buses without external level shifters.

Dynamic performance is characterized by matched tPLH/tPHL propagation delays (≤7.0 ns max at VCC = 4.5–5.5 V, CL = 15 pF), low power dissipation capacitance (CPD = 18 pF), and robust ESD protection (HBM >2000 V, CDM >1000 V), enabling reliable operation in noisy industrial environments.

FAQ

Can 74AHC1G02GW,125 operate reliably at 2.0 V supply?

Yes. The device is fully specified down to 2.0 V VCC, with guaranteed VIH ≥1.5 V and VOL ≤0.36 V at 4.0 mA load. Propagation delay increases to 10.5 ns max (CL = 15 pF), but logic functionality and noise margins remain intact across the full -40 °C to +125 °C range.

Is the 74AHC1G02GW,125 pin-compatible with 74AHCT1G02GW,125?

Yes. Both share identical TSSOP5 (SOT353-1) pinout: Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. They differ only in input threshold specifications (CMOS vs. TTL), allowing direct physical substitution where logic thresholds align with system requirements.

What is the maximum capacitive load this NOR gate can drive without exceeding timing specs?

At VCC = 5.0 V, the device maintains tpd ≤7.0 ns with CL = 15 pF and ≤9.5 ns with CL = 50 pF. For designs requiring tighter timing, keep total load (including trace and input capacitance) ≤15 pF; for relaxed timing budgets, up to 50 pF is supported with verified signal integrity.

Does this part require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be tied to VCC or GND to prevent floating states and increased ICC. The datasheet explicitly prohibits leaving inputs unconnected due to CMOS input structure; however, no external resistors are needed - direct connection suffices and minimizes board area and leakage paths.
