Nexperia USA Inc. 74ABT04D,112

Overview

74ABT04D from Nexperia is a hex inverter IC with BiCMOS technology, operating across 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 logic buffer in bus interface circuits, clock distribution networks, and digital control signal conditioning where TTL-compatible input thresholds and low-output skew (<0.5 ns) are required.

For engineers reviewing the 74ABT04D datasheet, 74ABT04D pinout, 74ABT04D application, or 74ABT04D equivalent, this device is selected for high-speed 5 V logic inversion with robust ESD immunity (HBM >2000 V), latch-up resistance (>500 mA), and guaranteed operation from –40 °C to +85 °C in SO14 packaging.

Technical Context

The 74ABT04D implements six independent CMOS-compatible inverters in a single SO14 package, each featuring TTL-level input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and rail-to-rail output swing under load. Its BiCMOS architecture combines bipolar speed with CMOS low static current, enabling 1.6 ns typical tPHL at 5.0 V.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA - critical for hot-swap and multi-rail system designs. Output skew between any two channels is guaranteed ≤0.5 ns, supporting synchronized signal inversion in timing-critical paths.

Key Specifications

FAQ

Can the 74ABT04D operate with a 3.3 V supply?

No. The 74ABT04D is specified only for 4.5 V to 5.5 V operation per Table 5. At 3.3 V, input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) remain valid, but output drive collapses below specification, propagation delay increases beyond 5 ns, and IOFF functionality is not guaranteed. Use 74LVC04 for 3.3 V systems.

Does the 74ABT04D require external pull-up resistors on its outputs?

No. Its push-pull CMOS/BiCMOS outputs actively drive both HIGH and LOW states without external biasing. Pull-ups are unnecessary unless open-drain emulation is intentionally required - which this device does not support.

What is the maximum capacitive load the 74ABT04D can drive reliably?

Per Figure 5 test conditions and Table 8, the device is characterized up to 50 pF load capacitance. Driving >100 pF may increase propagation delay beyond 4.1 ns and cause ringing due to output impedance mismatch; for heavier loads, add series termination or use a dedicated buffer.

Is the 74ABT04D pin-compatible with older 74LS04 or 74HC04 devices?

Yes, electrically and physically: same SO14 pinout (1A–6A inputs on odd pins, 1Y–6Y outputs on even pins, GND on 7, VCC on 14). However, ABT offers faster speed, higher drive, and IOFF - unlike LS (bipolar, no IOFF) or HC (CMOS, no IOFF, slower at 5 V).
