1999 Apr 15
853–2157 21253
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
Same pinout and function as the FBL2033 except for 30Ω series
termination on 4 outputs making external resistors unnecessary
A port outputs include 30Ω termination to reduce overshoot and
undershoot
