Description

   The 74ABT2245 high-performance BiCMOS device combines  low static and dynamic power dissipation with high speed.

   The 74ABT2245 device is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an Output Enable (OE ) input for easy cascading and a Direction (DIR) input for direction control.

   The 74ABT2245 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 74ABT2245 is the same as the 74ABT245-1. The part number has been changed to reflect industry standards.
