FB2031
9-bit latched/registered/pass-thru Futurebus+ transceiver
2
1995 May 25
853-1714 15279
FEATURES
Latched, registered or straight through in
either A to B or B to A path
Drives heavily loaded backplanes with
equivalent load impedances down to 10
.
High drive 100mA BTL open collector
drivers on B-port
Allows incident wave switching in heavily
loaded backplane buses
Reduced BTL voltage swing produces less
noise and reduces power consumption
Built-in precision band-gap reference
provides accurate receiver thresholds and
improved noise immunity
Compatible with IEEE Futurebus+ or
proprietary BTL backplanes
Each BTL driver has a dedicated Bus GND
for a signal return
Controlled output ramp and multiple GND
pins minimize ground bounce
Glitch-free power up/power down operation
Low I

current
Tight output skew
Supports live insertion
