DESCRIPTION

The FBL2041/FBL2041I is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FBL2041 is an inverting transceiver.

FEATURES

• 7-bit BTL transceiver

• Separate I/O on TTL A-port

• Inverting

• Three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit arrangement

• 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

• Controlled output ramp and multiple GND pins minimize ground bounce

• Each BTL driver has a dedicated Bus GND for a signal return

• 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

• Industrial temperature range option available as FBL2041I
