Octal Registered Transceiver
General Description
The ABT2952 is an octal 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.
Ordering Code:
Device also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
