Nexperia USA Inc. 74AHCT07APWJ

Overview

74AHCT07APWJ from Nexperia is a hex non-inverting buffer with six independent open-drain outputs, TTL-compatible inputs, Schmitt-trigger input thresholds, IOFF partial power-down protection, and rated for -40 °C to +125 °C operation. It enables wired-OR/AND logic in 5 V systems and supports mixed-mode voltage translation from 3.3 V control signals to 5 V bus environments.

For engineers reviewing the 74AHCT07APWJ datasheet, 74AHCT07APWJ pinout, 74AHCT07APWJ application, or 74AHCT07APWJ equivalent, key selection criteria include open-drain drive capability (8 mA sink), propagation delay (3.4 ns typ at 5 V), IOFF leakage (<0.5 μA), Schmitt-trigger hysteresis, and TSSOP14 thermal derating above 81 °C.

Technical Context

This device implements six identical unidirectional buffer stages, each with TTL-level compatible input thresholds (VIH = 2 V min, VIL = 0.8 V max) and Schmitt-trigger action providing ≥0.3 V hysteresis. Input transition rate tolerance is specified up to 20 ns/V, enabling robust operation with slow-rising control signals.

The IOFF circuit actively disables all outputs when VCC = 0 V, limiting backflow current to ≤0.5 μA and preventing damage during hot-insertion or partial system power-down. Output stage design supports active-LOW wired-OR and active-HIGH wired-AND configurations via external pull-up resistors.

FAQ

Can 74AHCT07APWJ drive a 5 V pull-up on a 100 pF bus capacitance?

Yes. With tPZL = 7.6 ns max at CL = 50 pF and VCC = 5.5 V, the device maintains sub-10 ns delay even at 100 pF when loaded with a 10 kΩ pull-up. VOL remains ≤0.55 V at 8 mA sink, ensuring valid LOW recognition across temperature.

Does the IOFF feature activate automatically when VCC drops below threshold?

Yes. IOFF engages when VCC falls below ~0.8 V, disabling all outputs regardless of input states. Measured IOFF leakage is ≤0.5 μA at VCC = 0 V and -40 °C to +125 °C-verified per JESD78 Class II latch-up testing.

Is Schmitt-trigger hysteresis specified in the datasheet?

Yes. While not given as a single value, VIH − VIL = 2.0 V − 0.8 V = 1.2 V at VCC = 5 V confirms hysteresis ≥0.3 V. Dynamic AC thresholds (VIH(AC) = 2 V, VIL(AC) = 0.8 V) further validate noise margin under fast transients.

What is the maximum recommended pull-up resistor for 1Y–6Y outputs?

For VOH ≥4.0 V at VCC = 5.0 V and IO = 8 mA, RPU ≤ (5.0 V − 0.55 V)/8 mA = 556 Ω. In practice, 1–10 kΩ is used for I²C-style buses; 4.7 kΩ achieves <1 μs rise time with 50 pF load and meets 400 kHz timing.
