74F8963中文资料飞利浦数据手册PDF规格书

DESCRIPTION

The 74F8962 and 74F8963 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 150mV threshold region.

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 896 futurebus standards

• Built–in precision band–gap reference provides accurate receiver thresholds and improved noise immunity

• Multiple GND pins minimize ground bounce

• Glitch–free power up/power down operation
