74ABT240CMSA

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT240CMSA is an octal buffer and line driver with 3-state outputs, housed in a 20-lead Shrink Small Outline Package (SSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient temperature range from -40°C to +85°C. The device provides high drive capability with a maximum output sink current of 64 mA and a source current of 32 mA. Propagation delays are specified between 1.0 ns and 5.5 ns depending on load conditions.
