74ABT32PW,118

Overview

The Nexperia 74ABT32PW,118 is a quad 2-input OR gate in a TSSOP14 package. It operates on a supply voltage of 4.5 V to 5.5 V with TTL-compatible levels. Propagation delays range from 1.0 ns to 3.8 ns at 5.0 V. Output currents are -15 mA (high) and 20 mA (low). The device supports partial power-down via IOFF circuitry, preventing backflow current. Operating temperature spans -40 °C to +85 °C.

Feature Summary

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

Applications

• Partial power-down applications requiring controlled output states during power loss
• High-speed digital logic circuits utilizing OR gate functionality
• Systems interfacing between TTL-level devices and BiCMOS logic families

Procurement Notes

Verify the specific ordering suffix matches the required packaging format. Confirm that the component status remains active for production use. Ensure design compliance with absolute maximum ratings to avoid permanent damage. Check for any recent product change notices affecting specifications or assembly locations before finalizing procurement orders.

Selection Notes

Select this component when high-speed OR logic is required within a 5 V BiCMOS environment. The TSSOP14 package suits surface-mount designs needing compact footprints. Verify that input voltage levels remain within specified limits relative to the supply voltage. Consider the IOFF feature if the application involves partial power-down scenarios to protect downstream circuitry.

Part Context

This part belongs to the 74ABT series of BiCMOS logic gates manufactured by Nexperia. The ABT family combines bipolar speed with CMOS low power consumption.
