74ABT16952
16-Bit Registered Transceiver with TRI-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 en-
able and TRI-STATE output enable signals are provided
for each register The output pins are guaranteed to source
32 mA (24 mA mil ) and to sink 64 mA (48 mA mil)
Features
Y _{Separate clock clock enable and TRI-STATE output}
enable provided for each register
Y _{A and B output sink capability of 64 mA source capabil-}
ity of 32 mA
Y _{Guaranteed latchup protection}
Y _{High impedance glitch free bus loading during entire}
power up and power down cycle
Y _{Nondestructive hot insertion capability}
