16-Bit Registered Transceiver with TRI-STATEÉ Outputs
General Description
The ’ABT16952isa 16-bit registered transceiver. Two 8-bit
backto back registers store data flowingin both directions
betweentwo bidirectional buses. Separate clock, clocken-
able and TRI-STATEÉ output enable signalsare provided
for each register.The output pinsare guaranteedto sourcemA(24mA mil.)andto sink64mA(48mA mil).
Features Separate clock, clock enable and TRI-STATE output
enable providedfor each registerAandB output sink capabilityof64mA source capabil-
ityof32mA Guaranteed latchup protection High impedance glitch free bus loading during entire
powerupand power down cycle Nondestructivehot insertion capability
