General 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 30 Ohm 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.

Features

  • Octal bus interface
  • 3-State buffers
  • Live insertion/extraction permitted
  • Outputs include series resistance of 30W, making external termination resistors unnecessary
  • Output capability: +5mA/-32mA
  • Latch-up protection exceeds 500mA per Jedec Std 17
  • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model
  • Power-up 3-State
  • Same part as 74ABT244-1
  • Inputs are disabled during 3-State mode
