FB2041

7-bit Futurebus+ transceiver

1995 May 25

853-1561 15279

DESCRIPTION

The FB2041 is a 7-bit bidirectional BTL transceiver and is intended

to provide the electrical interface to a high performance wired-OR

bus. The FB2041 is an inverting transceiver.

The B-port drivers are Low-capacitance open collectors with

controlled ramp and are designed to sink 100mA. Precision band

gap references on the B-port insure very good noise margins by

limiting the switching threshold to a narrow region centered at 1.55V.

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

Ω.

• 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 I

CC current

• Tight output skew

• Supports live insertion

• Pins for the optional JTAG boundary scan function are provided

• High density packaging in plastic Quad Flatpack
