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 driver re-
ceiver pairs to utilize a single bus The bus loading is un-
changed when V
CC
e
0V The receiver incorporates hyster-
esis to provide greater noise immunity All devices utilize a
high current TRI-STATE output driver The DS7833
DS8833 and DS7835 DS8835 employ TRI-STATE outputs
on the receiver also
The DS7833 DS8833 are non-inverting quad transceivers
with a common inverter driver disable control and common
inverter receiver disable control
The DS7835 DS8835 are inverting quad transceivers with a
common inverter driver disable control and a common in-
verter receiver disable control
