SN74F240N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F240N is an octal buffer and line driver from the Texas Instruments F (FAST) logic series. It features eight inverting outputs with three-state capability, housed in a 20-pin PDIP 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 7 ns at 5 V, a high-level output current of -15 mA, and a low-level output current of 64 mA. It supports through-hole mounting and functions reliably across an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel or tube packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the manufacturer's datasheet specifications align with your system's voltage and thermal constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed signal inversion and strong drive capability are required for digital bus structures. The F-series offers faster performance than standard TTL variants while maintaining compatible logic levels. Consider the PDIP-20 package for prototyping or applications requiring through-hole installation rather than surface-mount solutions.
