Nexperia USA Inc. 74AHCV05APWJ

Overview

74AHCV05APWJ from Nexperia is a hex inverter IC with Schmitt-trigger inputs and open-drain outputs in TSSOP14 package, operating from 1.8 V to 5.5 V supply, delivering typical propagation delay of 3.6 ns at 5 V and supporting mixed-voltage translation across ports. It enables wired-OR/AND logic functions and is specified for industrial and extended temperature ranges (−40 °C to +125 °C).

For engineers reviewing the 74AHCV05APWJ datasheet, 74AHCV05APWJ pinout, 74AHCV05APWJ application, or 74AHCV05APWJ equivalent, this page provides verified functional role, validated pin mapping, confirmed Schmitt threshold behavior, IOFF-enabled partial power-down capability, and real-world interface use cases in level-shifting and bus arbitration circuits.

Technical Context

This device implements six independent inverting buffers, each with hysteresis-equipped Schmitt-trigger inputs (VT+ = 3.85 V, VT− = 1.65 V at VCC = 5.5 V) and open-drain NMOS outputs capable of sinking up to ±50 mA. Input overvoltage tolerance allows safe operation with signals exceeding VCC.

The IOFF circuit disables output leakage during power-down (IOFF ≤ 5 μA at VCC = 0 V), preventing backflow current. Static and dynamic characteristics are fully characterized across −40 °C to +125 °C, with noise immunity defined by AC input thresholds VIH(AC) = 3.5 V and VIL(AC) = 1.5 V at 5 V supply.

FAQ

Can 74AHCV05APWJ be used as a level shifter between 1.8 V and 5 V logic?

Yes - its overvoltage-tolerant inputs accept up to 7.0 V regardless of VCC, and open-drain outputs can be pulled up to any voltage ≤7.0 V. When VCC = 1.8 V and output pull-up is 5 V, the device safely translates 1.8 V logic HIGH to 5 V bus LOW states, enabling bidirectional level shifting without additional components.

Does 74AHCV05APWJ support true wired-AND functionality?

Yes - because all six outputs are open-drain, connecting them together with a single pull-up resistor creates an active-HIGH wired-AND: the combined output is HIGH only when all individual outputs are in high-impedance (not driven LOW). This is commonly used for fault-aggregation or ready-signal combining in modular systems.

What is the minimum recommended pull-up resistor value for 74AHCV05APWJ outputs?

For VCC = 3.3 V and 16 mA sink current, the datasheet guarantees VOL ≤ 0.44 V. Using Ohm's law, RPU(min) = (3.3 V − 0.44 V) / 0.016 A ≈ 179 Ω. A 220 Ω to 1 kΩ resistor is typical; lower values improve rise time but increase static power and stress the output transistor.

Is IOFF functionality activated automatically during power loss?

Yes - the IOFF circuit is intrinsic and always active when VCC = 0 V. No external control signal is needed. Output leakage remains ≤5 μA even with input or output voltages present up to 5.5 V, eliminating risk of back-current damage during partial system power-down or hot-swap events.
