2 / 14 page Philips Semiconductors Product specification FB2041 7-bit Futurebus+ transceiver 2 1995 May 25 853-1561 15279 DESCRIPTION The FB2041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FB2041 is an inverting transceiver. The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA. Precision band gap references on the B-port insure very good noise margins by limiting the switching threshold to a narrow region centered at 1.55V. FEATURES • 7-bit BTL transceiver • Separate I/O on TTL A-port • Inverting • Three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit arrangement • 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 • Controlled output ramp and multiple GND pins minimize ground bounce • Each BTL driver has a dedicated Bus GND for a signal return • Glitch-free power up/power down operation • Low I CC current • Tight output skew • Supports live insertion • Pins for the optional JTAG boundary scan function are provided • High density packaging in plastic Quad Flatpack QUICK REFERENCE DATA SYMBOL PARAMETER TYPICAL UNIT tPLH Propagation delay 3.7 ns tPHL AIn to Bn 2.7 ns tPLH Propagation delay 3.4 ns tPHL Bn to AOn 3.2 ns COB Output capacitance (B0 - B6 only) 6 pF IOL Output current (B0 - B6 only) 100 mA Standby 19 ICC Supply Current AIn to Bn (outputs Low or High) 40 mA ICC Supply Current Bn to AOn (outputs Low) 22 mA Bn to AOn (outputs High) 19 ORDERING INFORMATION PACKAGE COMMERCIAL RANGE VCC = 5V±10%; Tamb = 0 to +70°C INDUSTRIAL RANGE VCC = 5V±10%; Tamb = -40 to +85°C DWG No. 52-pin Plastic Quad Flatpack FB2041BB CD3207BB SOT379-1 |
