1998 Dec 07
853-2136 20492
FEATURES
3.3V version of FB2040A with 70% power savings
8-bit BTL transceivers
Separate I/O on TTL A-port
Inverting
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
CC
current
Tight output skew
Supports live insertion
Pins for the optional JTAG boundary scan function are provided
High density packaging in plastic Quad Flat Pack
