74AC11240DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC11240DWR is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It utilizes the EPIC (Enhanced-Performance Implanted CMOS) process to deliver high fan-out and improved fan-in capabilities. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It is organized as two independent 4-bit buffers with separate active-low output-enable inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet indicates availability in Plastic Small-Outline (DW), Shrink Small-Outline (DB), and Standard Plastic DIPs. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement, as specifications may vary based on production revisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density octal buffering with three-state capability. Ensure the design accommodates the specified input transition rates and output drive currents. Consider the power dissipation limits of the SOIC package if operating at maximum load conditions or elevated temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74AC logic family, which is based on the EPIC CMOS process. It serves as an octal variant within the broader 74-series logic lineup, providing enhanced speed and drive strength compared to standard TTL equivalents while maintaining CMOS low-power characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the 74ACT11240 for different voltage thresholds or the 74AHC11240 for lower voltage operation. Verify functional equivalence regarding propagation delays and output drive capabilities before substituting.
