74ABT04PW,112

Overview

The NXP USA Inc. 74ABT04PW,112 is a hex inverter utilizing BiCMOS technology, housed in a 14-lead TSSOP (SOT402-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features IOFF circuitry for partial power-down mode operation, preventing backflow current when powered down. Static characteristics include a maximum input leakage current of ±1.0 μA at VCC = 5.5 V and a typical supply current of 2 μA. Dynamic performance under recommended conditions (VCC = 5.0 V, CL = 50 pF) specifies a low-to-high propagation delay (tPLH) with a maximum of 3.4 ns and a high-to-low propagation delay (tPHL) with a maximum of 2.5 ns.

Feature Summary

• Incorporates IOFF circuitry to disable outputs during partial power-down, preventing potentially damaging backflow currents through the device.
• Provides direct interface compatibility with TTL logic levels while maintaining CMOS input specifications.
• Features robust latch-up protection exceeding 500 mA per JESD78B Class II Level A standards.

Applications

• Partial power-down applications requiring isolation of powered-down sections.
• High-speed digital signal inversion in 5 V logic systems.
• Interfaces between TTL-level sources and BiCMOS logic circuits.

Procurement Notes

Verify that the ordering suffix matches the specific TSSOP14 package configuration required for your design. Confirm the manufacturer designation aligns with current Nexperia or NXP product lines, as ownership transitions may affect documentation references. Ensure the component meets the specified RoHS compliance status for your assembly process requirements.

Selection Notes

Select this component when a hex inverter is needed for 5 V BiCMOS applications requiring high speed and TTL compatibility. The TSSOP14 package is suitable for surface-mount designs with space constraints. Consider the IOFF feature if the system requires safe handling of backflow currents during power-down states. Verify that the operating temperature range of -40 °C to +85 °C meets environmental demands.

Part Context

The 74ABT04 belongs to the ABT logic family, characterized by BiCMOS technology offering high speed and strong output drive capabilities. This family bridges the gap between standard CMOS and faster logic families, providing direct TTL interfacing. The PW suffix specifically denotes the thin shrink small outline plastic package variant, distinguishing it from the standard SOIC version.

Replacement Considerations

Direct pin-compatible replacements within the same ABT hex inverter family should be evaluated based on package type and electrical specifications. Verify that any substitute maintains the required IOFF functionality and TTL level compatibility. Cross-reference datasheets to ensure dynamic characteristics like propagation delay meet the original design constraints.

FAQ

How does the IOFF circuitry function in the 74ABT04?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current from flowing through the device into the power supply rails.

What is the maximum propagation delay for the 74ABT04PW,112?

Under recommended operating conditions (VCC = 5.0 V, CL = 50 pF), the maximum low-to-high propagation delay (tPLH) is 3.4 ns, and the maximum high-to-low propagation delay (tPHL) is 2.5 ns.
