DESCRIPTION
The FBL22031 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 10Ω.
• 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
• Same pinout and function as the FBL2033 except for 30Ω series termination
• The A output includes a a series resistor of 30Ω making external terminating resistors unnecessary
