1 / 10 page Philips Semiconductors Product specification FB2033 8-bit latched/registered/pass-thru Futurebus+ universal interface transceiver 1 1995 May 25 853-1717 15279 FEATURES • 8-bit transceivers • Latched, registered or straight through in either A to B or B to A path • Drives heavily loaded backplanes with equivalent load impedances down to 10 Ω. • 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 • Each BTL driver has a dedicated Bus GND for a signal return • Controlled output ramp and multiple GND pins minimize ground bounce • Glitch-free power up/power down operation • Low I CC current • Tight output skew • Supports live insertion QUICK REFERENCE DATA SYMBOL PARAMETER TYPICAL UNIT tPLH tPHL Propagation delay AIn to Bn 3.0 3.0 ns tPLH tPHL Propagation delay Bn to AOn 4.3 4.1 ns COB Output capacitance (B0 – Bn only) 6 pF IOL Output current (B0 – Bn only) 100 mA ICC Supply current AIn to Bn (outputs Low or High) 24 mA ICC Supply current Bn to AOn (outputs Low) 45 mA Bn to AOn (outputs High) 22 ORDERING INFORMATION PACKAGES COMMERCIAL RANGE VCC = 5V±10%; Tamb = 0°C to +70°C DRAWING NUMBER 52-pin Plastic Quad Flat Pack (QFP) FB2033BB SOT379-1 NOTE: Thermal mounting or forced air is recommended PIN CONFIGURATION 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 BUS GND B1 BUS GND B2 BUS GND B3 BUS GND B4 BUS GND B5 BUS GND B6 BUS GND LOGIC GND AO1 AO2 AO3 LOOPBACK AI4 AI5 8-Bit Universal Transceiver FB2033 52-lead PQFP AI2 AI3 AO4 AI6 LOGIC GND AO5 SG00068 |
