74ABT04PW,112

Overview

The Nexperia 74ABT04PW,112 is a hex inverter utilizing BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interface with TTL levels. The device incorporates IOFF circuitry for partial power-down applications, preventing damaging backflow current when powered down. It provides latch-up protection exceeding 500 mA per JESD78B class II level A and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +85 °C and is housed in a TSSOP14 package.

Feature Summary

• BiCMOS high-speed performance with direct TTL level interfacing
• IOFF circuitry enables safe partial power-down mode operation
• Robust latch-up protection exceeding 500 mA per JESD78B standard
• High electrostatic discharge tolerance for HBM and CDM events

Applications

• Partial power-down system architectures
• Digital signal inversion logic circuits
• TTL-compatible interface designs

Procurement Notes

Verify the specific ordering code 74ABT04PW,112 against the manufacturer's latest datasheet revision history to ensure compliance with current JEDEC standards. Confirm that the TSSOP14 package variant matches the required PCB footprint dimensions. Ensure design safeguards are implemented to prevent operation beyond absolute maximum ratings, as stress above these limits causes permanent damage.

Selection Notes

Select this component for applications requiring high-speed hex inversion within a 4.5 V to 5.5 V supply range. The inclusion of IOFF circuitry makes it suitable for systems needing controlled power-down states without backflow risks. Verify compatibility with TTL input levels if interfacing with legacy logic families. Consider the thermal characteristics and operating temperature range of -40 °C to +85 °C for environmental suitability.

Part Context

The 74ABT04 belongs to the ABT logic family, characterized by BiCMOS technology offering high speed and strong output drive capabilities. This specific part number denotes the PW suffix, indicating the TSSOP14 plastic thin shrink small outline package with a 4.4 mm body width. It serves as a fundamental building block for digital logic inversion within mixed-voltage environments.

Replacement Considerations

The 74ABT04D is an alternative version of the same logical function but utilizes the SO14 package instead of TSSOP14. Designers must verify pinout compatibility and physical footprint differences before substituting between package types.
