SN74HC240N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC240N is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC (High-speed CMOS) logic family. It features eight non-inverting outputs with three-state capability, allowing multiple drivers to share a bus without contention. The device operates within a supply voltage range of 2 V to 6 V and supports bidirectional data transmission. Packaged in a 20-pin DIP (Dual In-line Package), it is designed for high-speed digital applications requiring signal buffering and driving capabilities across standard industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required footprint, as the 'N' suffix typically denotes a 20-pin DIP. Confirm the specific grade (standard vs. automotive) if the application demands extended reliability standards. Check datasheet revisions for any pinout changes or updated electrical characteristics before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for 5V or lower logic systems. Ensure the load capacitance does not exceed the specified limits to maintain signal integrity. Compare propagation delay specifications against system timing requirements to verify compatibility with the target clock speeds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely adopted SN74HC series, known for compatibility with TTL inputs while offering CMOS noise immunity. The octal format consolidates multiple single-channel buffers into a single package, reducing board space compared to using individual gates. It serves as a foundational component in digital logic designs requiring signal isolation or amplification.
