DESCRIPTION

The 74F8960 and 74F8961 are octal bidirectional latched 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 100 mV threshold region and a 4ns glitch filter.

FEATURES

• Octal latched transceiver

• Drives heavily loaded backplanes with equivalent load impedances down to 10Ω

• High drive (100mA) open collector drivers on B port

• Reduced voltage swing (1 volt) produces less noise and reduces power consumption

• High speed operation enhances performance of backplane buses and facilitates incident wave switching

• Compatible with IEEE futurebus standards

• 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/down operation
