SN74LS240ML1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS240ML1 is an octal buffer and line driver belonging to the Low Power Schottky (LS) TTL logic family. It features two independent four-bit drivers with inverted outputs and three-state capability, housed in a 20-pin Small Outline Package (SOP). The device operates within a supply voltage range of 4.75 V to 5.25 V, typically rated at 5 V. It supports a commercial temperature range from 0°C to 70°C. Key electrical characteristics include input hysteresis for improved noise margins and input clamp diodes to limit high-speed termination effects.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer source carefully, as the 'SN' prefix typically indicates Texas Instruments origin while 'onsemi' is requested. Confirm the SOP-20 package matches the ML1 suffix. Ensure the component meets RoHS compliance requirements if specified for the project. Cross-reference the datasheet revision date to confirm technical accuracy against current standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with inverted logic levels. The LS series offers a balance of speed and power consumption suitable for general digital applications. Verify that the three-state enable signals align with the system's bus architecture. Ensure the SOP-20 footprint fits the PCB layout constraints compared to DIP alternatives.
