The SN65C1406 and SN75C1406 are low-power BiMOS devices containing three independent drivers and receivers that are used to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). These devices are designed to conform to TIA/EIA-232-F. The drivers and receivers of the SN65C1406 and SN75C1406 are similar to those of the SN75C188 quadruple driver and SN75C189A quadruple receiver, respectively. The drivers have a controlled output slew rate that is limited to a maximum of 30 V/us, and the receivers have filters that reject input noise pulses shorter than 1 us. Both these features eliminate the need for external components.
The SN65C1406 and SN75C1406 are designed using low-power techniques in a BiMOS technology.
