74ABT32D,118

Overview

The Nexperia 74ABT32D,118 is a quad 2-input OR gate utilizing Advanced BiCMOS Technology (ABT). It operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interfacing with TTL levels. The device incorporates IOFF circuitry for partial power-down mode operation, preventing damaging backflow currents when powered down. It features latch-up protection exceeding 500 mA per JESD78B Class II Level A and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Operating temperatures range from -40 °C to +85 °C.

Feature Summary

• Advanced BiCMOS technology provides high-speed performance and robust output drive capabilities.
• Integrated IOFF circuitry enables safe partial power-down mode by disabling outputs to prevent backflow current.
• Direct interface compatibility with TTL logic levels simplifies system integration.

Applications

• Partial power-down applications requiring isolation during power-off states
• High-speed digital logic circuits utilizing TTL-compatible signaling
• General-purpose Boolean logic implementation in 5V systems

Procurement Notes

Verify the specific package variant against design requirements, as the 74ABT32 series includes both SO14 and TSSOP14 options. Confirm that the selected component meets the required operating temperature range and electrical specifications for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high-speed OR logic operations at 5V. Ensure the PCB layout accommodates the SO14 package dimensions specified in SOT108-1. Verify that input transition rates remain within the 10 ns/V limit to maintain signal integrity and proper switching characteristics.

Part Context

This part belongs to the 74ABT family, which utilizes Advanced BiCMOS Technology to deliver superior speed compared to standard CMOS logic families. The 74ABT32 specifically implements four independent 2-input OR gates, providing versatile logic functionality for complex digital circuit designs requiring fast propagation delays.

Replacement Considerations

The 74ABT32PW,118 serves as a functional substitute offering identical logical operations but housed in a TSSOP14 package instead of the SO14 configuration. Designers must verify pinout compatibility and physical footprint constraints when considering this alternative package option.
