74ABT240PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT240PW,112 is an octal inverting buffer with 3-State outputs manufactured by NXP USA Inc. It operates within a DC supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device provides high output drive capabilities, specified as +64 mA for low-level output current and -32 mA for high-level output current. Propagation delay (tPLH/tPHL) is typically 3.1 ns at VCC = 5V with a 50 pF load. Input capacitance is 4 pF, while output capacitance is 7 pF when disabled.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' against official Nexperia or NXP documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the required 20-pin TSSOP Type I package dimensions. Confirm RoHS compliance status and REACH registration details directly with the manufacturer's latest product data sheets before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed signal inversion and strong drive capability on 5V logic buses. The dual enable structure allows flexible partitioning of the eight channels. Consider the 20-pin TSSOP package constraints regarding thermal management and board space compared to DIP or SSOP alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. The 74ABT240 specifically functions as an octal buffer, contrasting with non-inverting variants like the 74ABT244. It is part of a broader family of bus drivers and transceivers designed for high-speed digital interfaces in computing and telecommunications equipment.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes such as the 74ABT244 if non-inverting outputs are acceptable. Verify electrical characteristics match for any cross-brand replacements from manufacturers like Texas Instruments or ON Semiconductor.
