74AC244MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74AC244MTCX is an octal buffer and line driver belonging to the AC logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 9 ns when operating at 3.3 V, and reduces to 7 ns at 5 V. The component supports surface mount installation and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as this part number is produced by multiple vendors including onsemi and Fairchild Semiconductor. Confirm the exact datasheet revision and pinout compatibility before integration. Ensure the selected variant matches the required voltage levels and package dimensions for the target design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed octal buffering with significant drive strength. The AC series offers improved switching performance compared to standard logic families. Consider the 20-pin TSSOP package for space-constrained surface mount applications requiring robust signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the widely used 74AC family of CMOS logic devices. It serves as a unidirectional buffer, distinct from bidirectional transceivers like the 74ACT245. The MTCX suffix indicates the TSSOP-20 surface mount package with tape and reel shipping configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MM74HC244MTCX is a compatible alternative offering similar functionality within the HC logic family. Designers should verify voltage compatibility and drive current specifications when substituting between AC and HC series components.
