DM8833
DM8833 is quad TRI-STATE transceivers manufactured by National Semiconductor.
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.
