Nexperia USA Inc. 74HC1G02GW,165

Overview

74HC1G02GW,165 from Nexperia is a single 2-input CMOS NOR gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 9 ns at VCC = 4.5 V and CL = 50 pF, symmetrical output impedance, and input clamp diodes enabling overvoltage-tolerant interfacing in level-shifting logic circuits.

For engineers reviewing the 74HC1G02GW,165 datasheet, 74HC1G02GW,165 pinout, 74HC1G02GW,165 application, or 74HC1G02GW,165 equivalent, this device serves as a space-constrained, low-power combinational logic element for signal inversion, enable/disable control, and bus arbitration in portable instrumentation, industrial I/O modules, and power management sequencers where rail-to-rail input compatibility and guaranteed noise immunity are required.

Technical Context

The 74HC1G02GW,165 implements standard positive-logic NOR functionality (Y = NOT(A OR B)) using silicon-gate CMOS technology, with inputs tolerant of voltages exceeding VCC due to integrated clamp diodes and current-limiting resistor support. Its static input thresholds scale with VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), ensuring robust operation across the full 2.0–6.0 V range.

Dynamic behavior is characterized by balanced tPLH/tPHL propagation delays, low CPD (18 pF), and stable VOL/VOH performance under load (e.g., VOH ≥ 4.13 V at IO = –2.0 mA, VCC = 4.5 V). It meets JESD7A and JESD8C compliance, with HBM ESD rating >2000 V and latch-up immunity >100 mA per JESD78 Class II Level B.

FAQ

What is the maximum recommended operating frequency for 74HC1G02GW,165?

The device has no specified maximum clock frequency, as it is a combinational logic gate-not a clocked device. Its usable toggle rate is limited by propagation delay and load capacitance: with CL = 50 pF and VCC = 4.5 V, tpd ≈ 9 ns (typ), supporting reliable operation up to ~30 MHz in feedback-free configurations. System-level timing margins must account for worst-case 27 ns delay at +125 °C.

Can 74HC1G02GW,165 safely interface with 5 V inputs while powered from 3.3 V?

No-its inputs are not 5 V tolerant when VCC = 3.3 V. The absolute maximum input voltage is VCC + 0.5 V = 3.8 V. To interface 5 V signals, use current-limiting resistors with the internal clamp diodes (per datasheet Section 1), or select the 74HCT1G02GW,165 variant, which features TTL-compatible inputs validated up to 5.5 V regardless of VCC.

Does 74HC1G02GW,165 require external pull-up or pull-down resistors on unused inputs?

Yes-unused inputs must be terminated to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable output states, and potential oscillation due to noise coupling. For NOR logic, tying unused inputs to GND ensures they contribute no assertion to the output; tying to VCC forces output LOW. A 10 kΩ resistor suffices for either case.

Is the TSSOP5 (SOT353-1) package RoHS-compliant and lead-free?

Yes-the 74HC1G02GW,165 uses a lead-free, halogen-free, RoHS-compliant TSSOP5 package (SOT353-1) with matte tin (Sn) termination. Reflow profile follows JEDEC J-STD-020 Rev. E, with peak temperature ≤260 °C and time above liquidus 60–150 seconds. Moisture sensitivity level is MSL1-unlimited floor life at ≤30 °C/60% RH.
