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
