Quad Tri-state Bus Transceivers - National Semiconductor

This family of TRI-STATE Bus Transceivers DS7834 DS8834 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. Both devices utilize a high current TRI-STATE output driver. The DS7834 DS8834 employs TTL outputs on the receiver. The DS7834 DS8834 are inverting quad transceivers with two common inverter driver disable controls. By National Semiconductor Corporation
