Overview
INTEGRATED CIRCUITS 74ABT2244 Octal buffer/line driver with 30Ω series termination resistors (3-State) Product specification Supersedes data of 1996 Oct 23 IC23 Data Handbook 1998 Jan 16 Philips Semiconductors Philips Semiconductors Product specification Octal buffer/line driver with 30Ω series termination resistors (3-State) 74ABT2244 FEATURES • Octal bus interface • 3-State buffers • Live insertion/extraction permitted • Outputs include series resistance of 30Ω, making external termination resistors unnecessary DESCRIPTION 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 30Ω 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 receivers/transmitters.
The 74ABT2244 is the same as the 74ABT244-1.
The part number has been changed to reflect industry standards.
