Overview
The Nexperia 74ABT32DB,118 is a quad 2-input OR gate in the ABT logic family. 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 with propagation delays up to 3.8 ns at 5.0 V. It includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up protection exceeds 500 mA per JESD78B Class II Level A. Operating temperature ranges from -40 °C to +85 °C.
Feature Summary
- Quad 2-input OR gate configuration
- IOFF circuitry for partial power-down mode operation
- High-speed BiCMOS output drive capability
- Direct interface with TTL levels
Applications
- Partial power-down bus interface systems
- TTL-to-CMOS logic level translation
- High-speed digital signal processing circuits
Procurement Notes
Verify the specific package type against the datasheet ordering information. The 'DB' suffix typically indicates an SSOP package, but the official product data sheet for the 74ABT32 lists only SO14 (D) and TSSOP14 (PW) packages. Confirm if the 'DB' variant is a legacy or discontinued package version before procurement to ensure compatibility with design footprints.
Selection Notes
Select this component for applications requiring fast switching speeds and direct TTL compatibility. The ABT series offers higher speed than standard HC/HCT families while maintaining CMOS power efficiency. Ensure the design accommodates the 4.5 V to 5.5 V supply requirement and utilizes the IOFF feature if partial power-down functionality is needed to protect downstream components.
Part Context
The 74ABT32 belongs to Nexperia's ABT logic family, which combines Bipolar and CMOS technologies for enhanced speed and drive strength. This family is designed for high-performance digital applications where propagation delay and output current are critical factors. The quad 2-input OR gate structure allows for complex logical operations within a single integrated circuit package.
Replacement Considerations
The 74ABT32DB (SSOP14) was removed from the product specification in revision v.4 (October 2020). Current production versions are available in SO14 (74ABT32D) and TSSOP14 (74ABT32PW) packages. Verify pinout compatibility if substituting with these active packages.
