DM7839/DM8839 quad TRI-STATE® transceivers
general description
This family of TRI·STATE® party line trans·
ceivers offer extreme versatility in bus organized
data transm ission 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/receiver pairs to utilize a single
bus. The bus loading is unchanged when Vee = OV.
The receiver incorporates hysteresis to provide
greater noise immunity. All devices utilize a high
current TRI·STATE output driver. The DM7833/
DM8833 and DM7835/DM8835 employ TR1·
STATE outputs on the receiver also, while on
the DM7834/DM8834 and DM7839/DM8839 the
receiver outputs are standard active pu II up T2 L.
The DM7833/DM8833 are non-inverting quad
transceivers With a common drtver disable can·
trol and a common receiver disable control.
The DM7839/DM8839 are non· inverting quad
transceivers with a common two-input driver
disable control.
The DM7834/DM8834 are inverting Quad trans·
ceivers with. a common two input driver disable
control.
