Nexperia USA Inc. 74ABT04PW,112

Overview

74ABT04PW from Nexperia is a hex inverter logic IC with BiCMOS architecture, operating at 4.5 V to 5.5 V supply, delivering 2.2 ns typical propagation delay (tPLH/tPHL), ±20 mA output drive, and IOFF-enabled partial power-down protection. It serves as a level-shifting signal conditioner in bus interface circuits, TTL-compatible control planes, and digital isolation stages.

For engineers reviewing the 74ABT04PW datasheet, 74ABT04PW pinout, 74ABT04PW application, or 74ABT04PW equivalent, this page delivers verified package mapping (TSSOP14/SOT402-1), confirmed IOFF behavior, static/dynamic electrical specs across -40 °C to +85 °C, and validated functional substitution options for legacy ABT-series designs.

Technical Context

The 74ABT04PW implements six independent CMOS-input/BiCMOS-output inverter gates in a single monolithic die. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA - critical for hot-swap and multi-rail system partitioning.

Each gate exhibits matched propagation delays (tPLH/tPHL ≤ 4.1 ns/3.0 ns max over temperature), sub-0.5 ns output skew, and TTL-level input compatibility (VIL ≤ 0.8 V, VIH ≥ 2.0 V) without external biasing - enabling direct replacement of 74LS04 and 74F04 in legacy board upgrades.

FAQ

Does 74ABT04PW support true bidirectional operation?

No. The 74ABT04PW is a unidirectional hex inverter with fixed input (A) and output (Y) terminals per channel. It lacks internal direction-control logic or bus-hold circuitry. Bidirectional data flow requires external control signals and separate transmit/receive paths - this device functions strictly as a signal polarity inverter.

Can 74ABT04PW be used with 3.3 V inputs while powered at 5 V?

Yes. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) accept 3.3 V logic HIGH safely. With VCC = 5 V, the input clamp voltage remains within spec (-1.2 V to +7.0 V), and input leakage stays below ±1.0 μA - no level shifter needed for interfacing with 3.3 V microcontrollers driving its A pins.

What is the maximum capacitive load the 74ABT04PW can drive reliably?

Per Nexperia's test conditions (Table 8), it is characterized up to 50 pF load capacitance with 500 Ω termination. At 20 mA drive strength and 2.2 ns typical tPD, it maintains signal integrity up to ~75 pF in controlled-impedance traces; beyond that, propagation delay increases and edge rate degrades - verify with IBIS simulation for >75 pF loads.

Is the IOFF feature activated automatically during power loss?

Yes. IOFF activates inherently when VCC drops below ~0.8 V - no external control signal required. The internal circuitry detects VCC collapse and disables all six outputs simultaneously, limiting backfeed current to ±100 μA regardless of input/output voltage states - ensuring safe operation during brown-out or hot-swap events.
