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.

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 ICC 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
