The 74ABT2244 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT2244 device is an octal buffer that is ideal for driving bus lines. The device features two Output Enables (1OE, 2OE), each controlling four of the 3-State outputs. The 74ABT2244 is designed with 30W series resistance in both the High and Low states of the output. This design reduces line noise in applications such as memory address drivers, clock drivers and bus recei
The Philips 74ABT2244 is a high-performance BiCMOS device designed as an octal buffer and line driver. It combines low static and dynamic power dissipation with high speed, making it ideal for driving bus lines such as memory address drivers, clock drivers, and bus receivers/transmitters.
The device features two Output Enables (1OE, 2OE), each controlling four of the 3-State outputs. A key design feature is the inclusion of 30-ohm series resistance in both the High and Low output states, which reduces line noise and eliminates the need for external termination resistors. The 74ABT2244 is functionally the same as the 74ABT244-1 but uses a part number reflecting industry standards.
