74F8965

Philips Semiconductors FAST Products Product specification 9-Bit address/data Futurebus transceiver, ADT 74F8965/74F8966 FEATURES 9–bit transceiver (both directions) Drives heavily loaded backplanes with equivalent load impedances down to 10 ohms High drive (100mA) open collector drivers on B port Reduced voltage swing (1V to 2V) produces less noise and reduces power consumption High speed operation enhances performance of backplane buses and facilitates incident wave switching Compatible with IEEE 896 futurebus standards and IEEE 1194 BTL standard Built–in precision band–gap reference provides accurate receiver thresholds and improved noise immunity Controlled output ramp and multiple GND pins minimize ground bounce Glitch–free power up/power down operation TYPE 74F8965 74F8966 Guaranteed skew of less than 2ns DESCRIPTION The 74F8965 and 74F8966 are 9–bit bidirectional latchable transceivers and are intended to provide the electrical interface to a high performance wired–OR bus. The B port inverting drivers are low–capacitance open collector with controlled ramp and are designed to sink 100mA from 2 volts. The B port inverting receivers have a precision band gap references for improved noise margins. The B port interfaces to ’Backplane Transceiver Logic’ (BTL). BTL features a reduced (1V to 2V) voltage swing for lower power consumption and a series diode on the drivers to reduce capacitive loading. Incident wave switching is employed, therefore BTL ...
