74ABT08D/AUJ

Overview

The NXP USA Inc. 74ABT08D/AUJ is a quad 2-input AND gate manufactured using BiCMOS technology, designed for high-speed digital logic applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interfacing with TTL levels. The device features IOFF circuitry that disables outputs during partial power-down states to prevent backflow current. It provides latch-up protection exceeding 500 mA per JESD78B Class II Level A standards and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• BiCMOS high-speed performance with output drive capabilities
• IOFF circuitry enables partial power-down mode operation
• Direct interface compatibility with TTL logic levels

Applications

• High-speed digital logic processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm product status as active or discontinued through authorized distributors before procurement. Ensure compliance with RoHS3 specifications and REACH regulations for the intended manufacturing region. Validate pinout alignment with the SO14 or TSSOP14 package outline referenced in the datasheet.

Selection Notes

Select this component when a quad 2-input AND gate is required for BiCMOS speed characteristics at 5 V logic levels. Consider the IOFF feature if the design requires preventing backflow currents during standby modes. Verify that the operating environment stays within the -40 °C to +85 °C range. Ensure input transition rates do not exceed 5 ns/V to maintain signal integrity.
