PI-Bus Transceiver
General DescriptionThe DS1776isan octal PI-bus Transceiver. TheAtoB path latched.B outputsare open collectorwith series Schottky
diode, ensuring minimumB output loading.B outputs also
have ramped rise andfall times (2.5ns typical), ensuring
minimum PI-bus ringing.B inputs have glitch rejectioncir-
cuitry,4ns typical.
Designed using National’s Bi-CMOS processfor bothlow
operatingand disabled power.AC performanceis optimized
forthe PI-Bus inter-operability requirements.
The DS1776isan octal latched transceiverandis intended providethe electrical interfacetoa high performance
wired-or bus. Thisbus hasa loaded characteristic imped-
ance rangeof 20Ωto 50Ω andis terminatedon eachend
witha 30Ωto 40Ω resistor.
The DS1776isan octal bidirectional transceiver with open
collectorB and TRI-STATE®A port output drivers.A latch
functionis providedforthe Aport signals.TheBport output
driveris designedto sink100mA from2V and featuresa
controlled linear rampto minimize crosstalk and ringingon
the bus.
Aseparate high level control voltage (VX)is providedto pre-
ventthe Aside output high level from exceeding future high
density processor supply voltage levels.For5V systems,VXtiedto VCC.
