74LVT240D,112

Overview

The Nexperia USA Inc. 74LVT240D,112 is an octal inverting buffer and line driver featuring 3-state outputs housed in a 20-lead SO plastic small outline package (SOT163-1). It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides high-speed performance with propagation delays up to 5.6 ns at 3.3 V. It supports output currents of +64 mA and -32 mA, includes bus hold inputs to eliminate external pull-up resistors, and features IOFF circuitry for partial power-down mode operation.

Feature Summary

• Octal bus interface with 3-state buffers controlled by two independent output enable inputs
• BiCMOS technology enabling high speed and robust output drive capability
• Bus hold data inputs maintain valid logic levels on unused pins without external components
• IOFF circuitry prevents damaging backflow current during partial power-down conditions

Applications

• High-speed data bus buffering applications
• Line driving for communication interfaces
• Clock distribution networks requiring inversion and buffering
• Systems requiring live insertion and extraction support

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the tube packaging format required for your assembly process. Confirm that the SO20 package dimensions align with your PCB footprint design rules. Ensure the 2.7 V to 3.6 V operating voltage range matches your system's power supply rails before finalizing procurement.

Selection Notes

Select this component when designing systems requiring octal signal inversion with high drive strength. The 3-state outputs allow multiple drivers to share a common bus. Verify compatibility with TTL input levels if interfacing with legacy logic families. Consider the thermal dissipation requirements given the total power dissipation limits specified in the datasheet.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage 3.3 V applications. It serves as a standard solution for buffering and driving signals in digital circuits. The D variant specifically denotes the SO20 plastic small outline package, distinguishing it from other package options like TSSOP available within the same logical function series.
