ORDERING INFORMATION
NOTE: Thermal mounting or forced air is recommended
PIN CONFIGURATION
1995 May 25
8-bit transceivers
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
8-bit latched/registered/pass-thru
Futurebus+ universal interface transceiver

COMMERCIAL RANGE
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
Tight output skew
Supports live insertion
