DESCRIPTION
The 74F776 is an octal bidirectional latched transceiver and is 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.
The 74F776 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 propagation delays are short. Although the voltage swing is less for BTL, so is its receiver threshold, therefore noise margins are excellent.
BTL offers low power consumption, low ground bounce, EMI and crosstalk, low capacitive loading, superior noise margin and low propagation delays. This results in a high bandwidth, reliable backplane.
FEATURES
• Octal latched transceiver
• Drives heavily loaded backplanes with equivalent load impedances
down to 10 ohms
• 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 Pi–bus and IEEE 896 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/power down operation
• Multiple package options
• Industrial temperature range available (–40°C to +85°C)
