INTEGRATED CIRCUITS FBL22040 3.3V BTL8-bit TTL to BTL transceiver Product specification IC23 Data Handbook 1998 Dec 07 Philips Semiconductors Philips Semiconductors Product specification 3.3V 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...
