INTEGRATED CIRCUITS 74ABT2244 Octal buffer/line driver with 30 series termination resistors (3-State) Product specification 1998 Jan 16 Supersedes data of 1996 Oct 23 IC23 Data Handbook Philips Semiconductors Product specification Octal buffer/line driver with 30 series 74ABT2244 termination resistors (3-State) FEATURES DESCRIPTION Octal bus interface The 74ABT2244 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. 3-State buffers The 74ABT2244 device is an octal buffer that is ideal for driving bus Live insertion/extraction permitted lines. The device features two Output Enables (1OE, 2OE), each Outputs include series resistance of 30, making external controlling four of the 3-State outputs. termination resistors unnecessary The 74ABT2244 is designed with 30 series resistance in both the High and Low states of the output. This design reduces line noise in Output capability: +5mA/32mA applications such as memory address drivers, clock drivers and bus Latch-up protection exceeds 500mA per Jedec Std 17 receivers/transmitters. ESD protection exceeds 2000 V per MIL STD 883 Method 3015 The 74ABT2244 is the same as the 74ABT244-1. The part number and 200 V per Machine Model has been changed to reflect industry standards.
