Product Summary
The SN74AVC1T45DCKR is designed for asynchronous communication between two data buses. The SN74AVC1T45DCKR transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The SN74AVC1T45DCKR is designed so that the DIR input is powered by VCCA. The input circuitry of the SN74AVC1T45DCKR on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess Icc and Iccz.
