Quad TRI-STATEÉ Bus Transceivers

This family of TRI-STATE Bus Transceivers DS7833 DS8833 DS7835 DS8835 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 VCC 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. By National Semiconductor Corporation
