CD74ACT244M Octal Buffer/Line Driver from Texas Instruments

The CD74ACT244M is a high-speed octal buffer and line driver designed to be used in high-performance memory-receiving circuits and is produced by Texas Instruments, a leader in semiconductor solutions. This integrated circuit is part of the ACT family, which stands for Advanced CMOS Technology, providing the device with a perfect balance between speed and power consumption.

The device contains eight non-inverting buffers with 3-state outputs designed to be employed in driving bus lines or buffer memory address registers. The 3-state control gate is a feature that allows the outputs to assume a high impedance state, thus ensuring that multiple outputs can be connected to a bus without the risk of contention.

Each buffer has a specific input-enable (OE) control, which makes it possible to place the output in the high-impedance state or to drive a logic-high or logic-low level on the output. This dual arrangement allows for greater flexibility in controlling the interface to bus lines, peripherals, and other logic circuits.

The CD74ACT244M operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL levels while offering the benefits of CMOS technology, such as reduced power consumption and increased noise margin. The device is characterized for operation from -55°C to 125°C, ensuring reliability in a wide range of environmental conditions.

Available in a SOIC-20 package, the CD74ACT244M ensures a small footprint on PCBs, which is essential for modern compact electronic designs. Its packaging is also conducive for automated surface-mount assembly processes, making it a convenient choice for mass production.

Key features of the CD74ACT244M include:

• Eight non-inverting buffers with 3-state outputs
