DESCRIPTION

The FBL22041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FBL22041 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 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

? 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

? The A port includes a series resistor of 30? making external terminating resistors unnecessary
