74ABT32DB,112

Overview

The Nexperia 74ABT32DB,112 is a quad 2-input OR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL level interfacing. The device features BiCMOS technology for high-speed performance and output drive capabilities. It includes IOFF circuitry to prevent backflow current during partial power-down states. Latch-up protection exceeds 500 mA per JESD78B Class II Level A standards. ESD protection meets ANSI/ESDA/JEDEC JS-001 Class 2 (>2000 V HBM) and JS-002 Class C3 (>1000 V CDM). Operating temperature ranges from -40 °C to +85 °C.

Feature Summary

• Latch-up protection exceeds 500 mA per JESD78B class II level A

Applications

• Partial power down applications
• Logic signal processing
• Digital circuit design

Procurement Notes

Verify the specific package type against the datasheet, as the 'DB' suffix typically denotes an SSOP14 package which was removed in revision v.4 of the 74ABT32 data sheet. Confirm current production status directly with Nexperia or authorized distributors, as ordering information in the provided documentation lists only SO14 (D) and TSSOP14 (PW) packages. Ensure compatibility with system voltage requirements of 4.5 V to 5.5 V.

Selection Notes

Select this component for applications requiring quad 2-input OR logic functions with high-speed BiCMOS performance. It is suitable for systems needing direct TTL level interfacing and robust latch-up protection. Consider the available packages (SO14 or TSSOP14) if the DB variant is obsolete. Verify that the operating environment stays within the specified -40 °C to +85 °C temperature range and utilizes the recommended 4.5 V to 5.5 V supply voltage.

Part Context

The 74ABT32 belongs to the 74ABT series of high-speed CMOS logic devices. This series is characterized by BiCMOS technology, offering speeds comparable to older bipolar families while maintaining CMOS low power consumption. The quad 2-input OR gate configuration allows for multiple logical operations within a single integrated circuit, commonly used in digital logic designs requiring parallel input processing.

Replacement Considerations

The 74ABT32DB,112 may be obsolete as the DB package was removed in revision v.4. Check for equivalents like 74ABT32D (SO14) or 74ABT32PW (TSSOP14). Verify pinout and electrical specifications match before substitution.
