Nexperia USA Inc. 74HC1G02GV,125

Overview

74HC1G02GV,125 from Nexperia is a single 2-input CMOS NOR gate in SC-74A (SOT753) 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 -40 °C to +125 °C temperature range. It serves as a compact logic-level combinatorial gate for signal inversion and enable/disable control in space-constrained digital subsystems.

For engineers reviewing the 74HC1G02GV,125 datasheet, 74HC1G02GV,125 pinout, 74HC1G02GV,125 application, or 74HC1G02GV,125 equivalent, this device is selected for low-voltage logic interfacing, power-on reset conditioning, and discrete gate-level signal arbitration where TTL compatibility is not required and supply flexibility down to 2.0 V is critical.

Technical Context

This device implements a single 2-input NOR function using standard CMOS technology, with input clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors. Its logic behavior follows the truth table: Y = NOT(A OR B), with defined HIGH/LOW input thresholds dependent on VCC.

It features symmetrical output drive capability (±12.5 mA), balanced tPLH/tPHL propagation delays, and static input leakage <1.0 μA at 6.0 V. The SC-74A package supports reflow soldering and provides thermal derating of 3.8 mW/K above 85 °C.

FAQ

What is the maximum allowable input voltage when VCC = 3.3 V?

Per datasheet Section 6.2 and Table 5, inputs are protected by clamp diodes. When VCC = 3.3 V, VI may exceed VCC up to VCC + 0.5 V = 3.8 V, provided input current is limited to ±20 mA. This allows safe interface to 5 V signals using a series resistor (e.g., 220 Ω limits current to ~7.7 mA at 5 V).

Can 74HC1G02GV,125 drive a 50 pF load at 10 MHz without signal degradation?

Yes. At VCC = 4.5 V and CL = 50 pF, typical propagation delay is 9 ns with rise/fall times <10 ns (derived from tpd and CPD = 18 pF). With 10 MHz (100 ns period), the gate contributes <10% of cycle time, and output drive (±12.5 mA) ensures full rail transitions into 50 pF with minimal overshoot or ringing.

Is this device qualified for automotive applications?

No. While rated for -40 °C to +125 °C, the 74HC1G02GV,125 is not AEC-Q200 qualified and lacks automotive-specific testing (e.g., HTOL, vibration, ESD beyond HBM/CDM). Nexperia explicitly states in Section 15 that non-automotive-qualified products are unsuitable for safety-critical or life-support systems.

How does the SC-74A (SOT753) package compare thermally to TSSOP5 (SOT353-1)?

The SC-74A package has a thermal resistance (RθJA) of approximately 263 K/W (calculated from Ptot derating: 250 mW at 85 °C, 3.8 mW/K slope), versus ~227 K/W for TSSOP5. This means SC-74A runs ~10 °C hotter at same power dissipation, but its smaller footprint (1.1 × 1.7 mm vs. 1.25 × 2.2 mm) benefits ultra-compact layouts where thermal mass is managed via copper pour.
