74FCT240ATQG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT 74FCT240ATQG is an octal inverting buffer and line driver utilizing advanced dual-metal CMOS technology. It features two functional blocks, each handling four bits of data with inverted outputs. The device provides three-state outputs controlled by active-low enable signals. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40 °C to +85 °C. The component is housed in a 20-pin Thin Shrink Small Outline Package (TSSOP) with a pin pitch of 0.65 mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ATQG' against the manufacturer's current datasheet to confirm package type and speed grade. Ensure the source document explicitly identifies Integrated Device Technology as the manufacturer, noting that Renesas Electronics may also produce equivalent parts under similar designations due to corporate acquisition history.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state control is required for 5V logic systems. The TSSOP-20 package is suitable for space-constrained surface-mount designs. Verify that the system requires inverted outputs, as non-inverting variants such as the 74FCT244 exist within the same family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS) logic family, designed to bridge the performance gap between standard CMOS and BiCMOS technologies. It offers propagation delays comparable to faster logic families while maintaining CMOS power consumption levels. The 74FCT240 series is widely used in digital systems requiring reliable data transmission over buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with Texas Instruments CY74FCT240ATQ or Renesas 74FCT240ATQG for potential equivalents. Confirm pinout compatibility and electrical specifications match before substitution.
