Want to post a buying lead? If you are not a member yet, please select the specific/related part number first and then fill the quantity and your contact details in the "Request for Quotation Form" on the left, and then click "Send RFQ".Your buying lead can then be posted, and the reliable suppliers will quote via our online message system or other channels soon.
These devices are monolithic low-power Schottky quadruple line receivers designed to satisfy the requirements of the standard interface between data-terminal equipment and data-communica- tion equipment as defined by TIA/EIA-232-F. A separate response-control (CONT) terminal is provided for each receiver. A resistor or a resistor and bias-voltage source can be connected between this terminal and ground to shift the input threshold levels. An external capacitor can be connected between this terminal and ground to provide input noise filtering.
The SN55189 and SN55189A are characterized for operation over the full military temperature range of 55°C to 125°C. The MC1489, MC1489A, SN75189, and SN75189A are characterized for operation from 0°C to 70°C.
