74ABT2240CMSA

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2240CMSA is an inverting octal buffer and line driver housed in a 20-lead Shrink Small Outline Package (SSOP). It features integrated 25Ω series resistors within the outputs to reduce signal ringing. The device operates with a supply voltage range of +4.5V to +5.5V and supports a free air ambient temperature range of -40°C to +85°C. Propagation delays from data inputs to outputs are specified between 1.0ns and 5.3ns, while output enable and disable times range from 1.5ns to 6.9ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package designation MSA20 corresponds to the 20-lead SSOP configuration. Confirm that the specific ordering code includes the 'C' suffix for commercial temperature ratings (-40°C to +85°C). Ensure the datasheet revision matches the required specifications for propagation delay and electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads such as MOS memory or bus transmitters. The integrated 25Ω resistors simplify board layout by eliminating the need for discrete series resistors. Verify that the application requires inverting logic functions and operates within the 4.5V to 5.5V supply voltage range.
