2000 Apr 18
853-2118 23499
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
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
DESCRIPTION
The FBL2031 is a 9-bit latched/registered transceiver featuring a
latched, registered or pass-thru mode in either the A-to-B or B-to-A
direction.
The FBL2031 is intended to provide the electrical interface to a high
performance wired-OR bus.
