74ABT244CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CMTC is an octal buffer and line driver featuring 3-STATE outputs. 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 provides non-inverting buffering with output sink capability of 64 mA and source capability of 32 mA. Propagation delays are specified at 1.0 ns to 3.6 ns for 50 pF loads and up to 8.5 ns for 250 pF loads. It includes guaranteed latchup protection and glitch-free bus loading during power cycles.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the ordering code MTC20 (20-Lead Thin Shrink Small Outline Package). Confirm that the component meets the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the 4.5V to 5.5V supply voltage specifications before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed data transmission with significant current drive requirements. The ABT technology offers faster switching speeds compared to standard CMOS logic families. Consider the 3-STATE output functionality for multiplexed bus architectures where multiple devices share common signal lines.
