Nexperia USA Inc. 74HCT1G02GV,125

Overview

74HCT1G02GV,125 from Nexperia is a single 2-input NOR gate logic IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, -40 °C to +125 °C temperature range, and SC-74A (SOT753) 5-pin surface-mount package. It delivers symmetrical output impedance, balanced propagation delays, and high noise immunity for signal-level logic inversion in compact digital subsystems.

For engineers reviewing the 74HCT1G02GV,125 datasheet, 74HCT1G02GV,125 pinout, 74HCT1G02GV,125 application, or 74HCT1G02GV,125 equivalent, this device supports precise logic-level translation in mixed-voltage interfaces, low-power control sequencing, and space-constrained board-level NOR functions requiring guaranteed TTL input compatibility and industrial-grade thermal performance.

Technical Context

The 74HCT1G02GV,125 implements standard positive-logic NOR functionality (Y = NOT(A OR B)) using CMOS technology with TTL-level input voltage thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). Its inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

Propagation delay is specified at 11 ns typical (24 ns max) for A/B-to-Y transitions under 4.5 V supply and 50 pF load, with output drive capability of ±2.0 mA at VCC = 4.5 V. Static power consumption remains below 20 μA over full temperature range, supporting low-quiescent-current system design.

FAQ

What is the maximum recommended operating voltage for 74HCT1G02GV,125?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD8C. Operation outside this window risks violating TTL input threshold specifications and may degrade propagation delay consistency or increase ICC beyond datasheet limits.

Can 74HCT1G02GV,125 drive a 50 pF capacitive load at 10 MHz?

Yes-it is characterized for 50 pF loads with 11 ns typical propagation delay at 4.5 V. At 10 MHz (100 ns period), the total delay represents <11% of the cycle, leaving ample margin for setup/hold timing. Output drive strength (±2.0 mA) ensures adequate slew rate for this load without excessive ringing.

Is 74HCT1G02GV,125 suitable for use with 3.3 V microcontrollers?

No-its TTL input thresholds require minimum VIH = 2.0 V, which 3.3 V logic typically meets, but its specified VCC range starts at 4.5 V. Supplying 3.3 V violates recommended operating conditions and results in undefined output levels, increased propagation delay, and potential functional failure per datasheet Section 9.

Does 74HCT1G02GV,125 require external pull-up or pull-down resistors on unused inputs?

No-unused inputs must be tied HIGH or LOW to prevent floating states, but no external resistors are needed due to internal input structure. Direct connection to VCC or GND is preferred; clamp diodes allow safe tie-to-rail without current limiting, unlike older bipolar logic families.
