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
.
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

Tight output skew
Supports live insertion
Pins for the optional JTAG boundary scan function are provided
High density packaging in plastic Quad Flatpack
