Quad TRI-STATE

Bus Transceivers

General Description

This family of TRI-STATE bus transceivers offers extreme

versatility in bus organized data transmission systems The

data bus may be unterminated or terminated DC or AC at

one or both ends Drivers in the third (high impedance) state

load the data bus with a negligible leakage current The

receiver input current is low allowing at least 100 driverre-

ceiver pairs to utilize a single bus The bus loading is un-

esis to provide greater noise immunity All devices utilize a

high current TRI-STATE output driver

The DS7833

DS8833 and DS7835DS8835 employ TRI-STATE outputs

on the receiver also

The DS7833DS8833 are non-inverting quad transceivers

with a common inverter driver disable control and common

inverter receiver disable control

The DS7835DS8835 are inverting quad transceivers with a

common inverter driver disable control and a common in-

verter receiver disable control
