Part Number : SN74ABT16500BDGG
Function : 18-BIT UNIVERSAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
Package : TSSOP 56 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
These 18-bit universal bus transceivers combine D-type latches and D-type flip-flops to allow data flow in transparent, latched, and clocked modes. Data flow in each direction is controlled by output-enable (OEAB and OEBA\), latch-enable (LEAB and LEBA), and clock (CLKAB\ and CLKBA\) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high.
