74ABT244CSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT244CSCX is an octal buffer and line driver with 3-STATE outputs. It operates within a supply voltage range of +4.5V to +5.5V. The device features non-inverting buffers 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 data-to-output transitions under standard AC load conditions (CL = 50 pF, RL = 500Ω). It includes guaranteed latchup protection and supports hot insertion.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package configuration against the ordering code. The 'C' suffix indicates commercial temperature range operation (-40°C to +85°C), while the 'S' denotes the SOIC package type. Confirm that the 'X' suffix corresponds to tape and reel packaging as specified in the datasheet ordering section. Ensure compatibility with 5V logic systems given the strict supply voltage requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed octal buffering is required for 5V systems. The ABT technology provides faster propagation delays compared to standard LS or HC families. Consider the 64 mA sink current for driving heavy loads or long traces. Verify that the system environment does not exceed the absolute maximum ratings for input voltage or short-circuit current to prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, which utilizes BiCMOS technology for high-speed performance. It is functionally compatible with other 74ABT devices but offers superior speed over older TTL-compatible CMOS families. The octal configuration allows for efficient handling of wide data buses in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts from other manufacturers such as SN74ABT244. Ensure pinout compatibility and verify that electrical characteristics like propagation delay and drive current meet the original design specifications.
