FEATURES
• 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
Ω.
• 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
CC current
• Tight output skew
• Supports live insertion
• Pins for the optional JTAG boundary scan function are provided
• High density packaging in plastic Quad Flatpack
• 5V compatible I/O on A-port
