74ABT240CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT240CMTC is an octal buffer and line driver belonging to the 74ABT logic family. It features inverting outputs with three-state capability, designed for high-speed bus-oriented transmission. The device operates within a supply voltage range of 4.5V to 5.5V. It utilizes a 20-pin TSSOP surface-mount package. Key electrical characteristics include a propagation delay of 3.1ns at 5V with 50pF load, high output drive currents of 32mA source and 64mA sink, and low static current consumption.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent inverting buffer channels for high-density circuit design.
• Three-state outputs enable direct connection to bus lines without external pull-up or pull-down resistors.
• Advanced BJT-Transistor Technology (ABT) architecture delivers high-speed performance with reduced power dissipation.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers for high-speed data storage systems.
• Clock distribution networks requiring precise timing and signal integrity.
• Bus-oriented transmitters and receivers in computer architectures.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor has undergone corporate restructuring and integration into ON Semiconductor. Ensure the specific orderable part number matches the required package variant and suffix codes. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring fast switching speeds combined with moderate power consumption. The ABT technology offers a balance between AC speed and LVTTL power efficiency. Ensure the application voltage remains strictly within the 4.5V to 5.5V range to maintain specified timing parameters and avoid device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader 74ABT series of high-speed logic devices. It serves as a functional equivalent to other octal buffers like the 74ACT240 but with distinct electrical characteristics tailored for specific performance profiles. The CMTC suffix denotes the specific TSSOP package type used for surface-mount assembly.
