74ABT244CSJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CSJ is an octal buffer and line driver with 3-STATE outputs, housed in a 20-Lead Small Outline Package (SOP). It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device features non-inverting buffers with guaranteed output skew and simultaneous switching specifications. Output drive capabilities include a sink current of 64 mA and a source current of 32 mA. Propagation delays are specified at 1.0 ns to 3.6 ns under standard conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation M20D corresponds to the 20-Lead SOP variant when sourcing. Confirm that the component meets RoHS requirements if applicable to the target assembly process. Check for any specific handling precautions related to the ABT logic family characteristics during installation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed data buffering with strong drive strength. Ensure the system voltage remains strictly between 4.5V and 5.5V. Consider the 20-SOP footprint constraints and verify thermal dissipation needs given the high output current capabilities under heavy load conditions.
