74ABT16952
16-Bit Registered Transceiver with 3-STATE Outputs
General Description
The ABT16952 is a 16-bit registered transceiver. Two 8-bit
back to back registers store data flowing in both directions
between two bidirectional buses. Separate clock, clock
enable and 3-STATE output enable signals are provided for
each register. The output pins are guaranteed to source 32
mA and to sink 64 mA.
Features
