Nexperia USA Inc. 74AHCT1G32GV,125

Overview

74AHCT1G32GV,125 from Nexperia is a single 2-input OR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5-pin SC-74A (SOT753) package, and guaranteed operation from −40 °C to +125 °C. It delivers symmetrical output drive (±8 mA), propagation delay as low as 3.3 ns (typ, CL = 15 pF, VCC = 5 V), and overvoltage-tolerant inputs up to 5.5 V - enabling level translation in mixed-voltage digital interfaces such as 3.3 V MCU GPIO interfacing to 5 V peripherals.

For engineers reviewing the 74AHCT1G32GV,125 datasheet, 74AHCT1G32GV,125 pinout, 74AHCT1G32GV,125 application, or 74AHCT1G32GV,125 equivalent, this device serves as a compact, temperature-hardened OR gate for signal combining, enable logic, interrupt arbitration, and voltage-level bridging in industrial control, automotive body electronics, and embedded sensor subsystems where TTL input compatibility and wide ambient range are required.

Technical Context

The 74AHCT1G32GV,125 implements standard positive-logic OR functionality (Y = A + B) using CMOS transistor topology with TTL-level input stage design. Its input threshold is fixed at VIH ≥ 2.0 V and VIL ≤ 0.8 V across 4.5–5.5 V supply, ensuring reliable recognition of legacy 5 V TTL signals while operating from modern 5 V rails.

It features symmetrical output impedance and balanced tPLH/tPHL propagation delays (max 9.0 ns at −40 °C to +125 °C, CL = 15 pF), enabling predictable timing in combinatorial logic paths. Input overvoltage tolerance to 5.5 V allows safe connection to higher-voltage nodes without external clamping.

FAQ

What is the maximum recommended operating frequency for 74AHCT1G32GV,125?

The device has no clock - it is combinational logic. Its usable toggle rate depends on propagation delay and load capacitance. With CL = 15 pF and VCC = 5 V, tpd ≤ 9.0 ns (max over temperature), supporting reliable operation up to ~55 MHz in feedback-free paths. For synchronous designs, ensure setup/hold margins relative to clock edges.

Can 74AHCT1G32GV,125 operate with a 3.3 V supply?

No. The 74AHCT variant is specified only for VCC = 4.5 V to 5.5 V. At 3.3 V, input thresholds (VIH ≥ 2.0 V) may not be met reliably, and output drive degrades significantly. Use 74AHC1G32GV,125 instead for 3.3 V operation with CMOS thresholds.

Is 74AHCT1G32GV,125 pin-compatible with other 5-pin OR gates like SN74LVC1G32?

Yes - both use SOT753 (SC-74A) packaging with identical pin 1 location and pinout (A, B, GND, Y, VCC). However, electrical behavior differs: SN74LVC1G32 uses LVTTL thresholds and supports 1.65–5.5 V VCC, while 74AHCT1G32 requires ≥4.5 V and provides stricter TTL-level compatibility.

Does 74AHCT1G32GV,125 require external pull-up or pull-down resistors on inputs?

No. Inputs are internally terminated and do not float; they exhibit <0.1 μA leakage (max) and defined VIH/VIL thresholds. External resistors are unnecessary unless implementing wired-OR with open-drain sources - in which case a pull-up on Y is required, not on A/B.
