FBL22031

INTEGRATED CIRCUITS FBL22031 9-bit BTL 3.3V latched/registered/pass-thru Futurebus+ transceiver with 30Ω termination Product specification Supersedes data of 1998 Sep 04 2000 Apr 18 Philips Semiconductors Philips Semiconductors Product specification 9-bit BTL 3.3V latched/registered/pass-thru Futurebus+ transceiver with 30Ω termination FBL22031 FEATURES path Latched, registered or straight through in either A to B or B to A Drives heavily loaded backplanes with equivalent load impedances down to 10Ω. 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 Tight output skew Supports live insertion Pins for the optional JTAG boundary scan function are provided High density packaging in plastic Quad Flatpack 5V compatible I/O on A-port Same pinout and function as the FBL2033 except for 30Ω series termination The A output includes a a series resistor of 30Ω making external terminating resistors unnecessary 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 DESCRIPTION The FBL22031 is a 9-bit latched/registered transceiver featuring a latched, registered or pas...
