FB2033

Philips Semiconductors Product specification 8-bit latched/registered/pass-thru Futurebus+ universal interface transceiver FB2033 FEATURES 8-bit transceivers Latched, registered or straight through in either A to B or B to A path Built-in precision band-gap reference provides accurate receiver thresholds and improved noise immunity Drives heavily loaded backplanes with equivalent load impedances down to 10Ω. Compatible with IEEE Futurebus+ or proprietary BTL backplanes Each BTL driver has a dedicated Bus GND for a signal return 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 Glitch-free power up/power down operation Low ICC current Tight output skew Supports live insertion TYPICAL 3.0 3.0 4.3 4.1 6 100 24 45 22 mA UNIT ns ns pF mA QUICK REFERENCE DATA SYMBOL tPLH tPHL tPLH tPHL COB IOL ICC PARAMETER Propagation delay AIn to Bn Propagation delay Bn to AOn Output capacitance (B0 – Bn only) Output current (B0 – Bn only) AIn to Bn (outputs Low or High) Supply current Bn to AOn (outputs Low) Bn to AOn (outputs High) ORDERING INFORMATION PACKAGES 52-pin Plastic Quad Flat Pack (QFP) NOTE: Thermal mounting or forced air is recommended COMMERCIAL RANGE VCC = 5V±10%; Tamb = 0°C to +70°C FB2033BB DRAWING NUMBER SOT379-1 PIN CONFIGURATI...
