INTEGRATED CIRCUITS FBL2040 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 FBL2040 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 10Ω. Compatible with IEEE Futurebus+ or proprietary BTL backplanes 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 Built-in precision band-gap reference provides accurate receiver thresholds and improved noise immunity QUICK REFERENCE DATA SYMBOL tPLH tPHL tPLH tPHL COB IOL Propagation delay AIn to Bn Propagation delay Bn to AOn Output capacitance (B0 – B7 only) Output current (B0 – B7 only) Standby AIn to Bn (outputs Low ) ICC Supply current Bn to AOn (outputs Low) AIn to Bn (outputs High) Bn to AOn (outputs High) PARAMETER TYPICAL 4.4 ...
