ON Semiconductor MC74ACT244DTR2 Octal Buffer/Line Driver
The ON Semiconductor MC74ACT244DTR2 is a high-performance, octal buffer and line driver designed to interface with 8-bit microprocessors and bus-oriented systems. This integrated circuit is part of the high-speed CMOS ACT family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.
This device is equipped with two separate enable inputs (1G and 2G) for each set of four buffers, providing flexibility in controlling the flow of data. The MC74ACT244DTR2 features non-inverting buffers with high-current output capability suitable for driving highly capacitive or low-impedance loads. The high-impedance state and increased high-logic-level drive provide this line driver with the capability to be used as a memory address driver, clock driver, and bus-oriented transmitter or receiver.
