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.

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

• Guaranteed skew of less than 2ns
