SN74AS240ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS240ADWR is an octal buffer and line driver from the Texas Instruments AS logic series. It features eight inverting outputs with three-state capability, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 6.5 ns, a high-level output current of -15 mA, and a low-level output current of 64 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the tape-and-reel packaging configuration intended for automated assembly processes. Confirm that the AS logic family specifications align with the target system's speed and power requirements before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed operation is critical alongside strong drive capabilities. The AS series offers faster switching speeds compared to standard LS or ALS families. Ensure the design accommodates the higher static current consumption inherent to bipolar-based logic technologies.
