74ABT2244CMSAX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2244CMSAX is an octal buffer and line driver featuring integrated 25 Ω series resistors in the outputs. It operates within a supply voltage range of +4.5V to +5.5V and supports ambient temperatures from -40°C to +85°C. The device provides non-inverting logic with high-impedance, glitch-free bus loading during power cycles. Propagation delays are specified between 1.0 ns and 4.4 ns at VCC = 5V with CL = 50pF. Output drive capabilities include a minimum HIGH state voltage of 2.0V at -32mA and a maximum LOW state voltage of 0.8V at 15mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'X' corresponds to tape and reel packaging as specified in the datasheet. Confirm the package type matches the MSA20 designation for the 20-Lead Shrink Small Outline Package (SSOP). Ensure compatibility with the recommended operating conditions regarding supply voltage and temperature ranges before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads such as MOS memory or bus transmitters where signal integrity is critical. The internal 25 Ω resistors simplify design by reducing the need for external termination components. Verify that the required propagation delay fits within the system timing constraints defined by the AC electrical characteristics.
