3V BTL 8-bit TTL to BTL transceiver FBL22040 FEATURES • Resistor version of FB2040 • 8-bit BTL transceivers • Separate I/O on TTL A-port • Inverting • Drives heavily loaded backplanes with equivalent load impedances down to 10Ω.
• Controlled output ramp and multiple GND pins minimize ground bounce • 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 • 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 Flat Pack • Same pin and function as FBL2040 except for a 30Ω series termination resistor • Built-in precision band-gap reference provides accurate receiver thresholds and improved noise immunity • The A outputs include a series resistor of 30Ω making external terminating resistors unnecessary • Compatible with IEEE Futurebus+ or proprietary BTL backplanes QUICK REFERENCE DATA SYMBOL tPLH tPHL tPLH tPHL COB IOL PARAMETER Propagation delay AIn to Bn Propagation delay Bn to AOn Output capacitance (B0 – B7 only) Output current (B0 – B7 only) TYPICAL 4.
