74ABT240CSCX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT240CSCX is an octal buffer and line driver featuring three-state outputs, designed for high-speed digital applications. It operates within a supply voltage range of 4.5V to 5.5V. The device provides low output impedance and reduced power consumption compared to standard logic families. Key electrical parameters include a propagation delay of 3.1ns at 5V with a 50pF load, a high-level output current of 32mA, and a low-level output current of 64mA. It functions as an inverting bus driver suitable for memory address and clock driving.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSCX' against official Fairchild or ON Semiconductor documentation to confirm package type (typically TSSOP) and tape-and-reel quantity. Ensure the component matches the required operating temperature range and voltage specifications for your design. Cross-reference the manufacturer part number with current datasheets to confirm availability and pinout compatibility before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for 5V logic systems. It serves as a suitable replacement for older 74ACT240 designs where lower power consumption and higher speed are needed. Consider the TSSOP package constraints if space is limited. Verify input compatibility with TTL or CMOS levels depending on the specific variant requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ABT series, which utilizes advanced BiCMOS technology to combine the speed of AC logic with low power consumption. It is functionally similar to the 74ACT240 but offers improved performance metrics. The series is widely used in telecommunications and computer systems requiring reliable data transmission over buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74ABT240 from Texas Instruments or the MC74ABT240 from ON Semiconductor. These parts share identical logical functionality and pinouts. Verify that the alternative package matches the PCB footprint and that the thermal characteristics meet the application's needs.
