description
The SN75C1406 is a low-power BiMOS device containing three independent drivers and receivers that are used
to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). This device is
designed to conform to TIA/EIA-232-F . The drivers and receivers of the 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/µs, and the receivers have filters that reject input noise
pulses shorter than 1 µs. Both these features eliminate the need for external components.
The SN75C1406 is designed using low-power techniques in a BiMOS technology. In most applications, the
receivers contained in these devices interface to single inputs of peripheral devices such as ACEs, UARTs, or
microprocessors. By using sampling, such peripheral devices are usually insensitive to the transition times of
the input signals. If this is not the case, or for other uses, it is recommended that the SN75C1406 receiver outputs
be buffered by single Schmitt input gates or single gates of the HCMOS, ALS, or 74F logic families.
The SN75C1406 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to the network ground terminal.
2. The package thermal impedance is calculated in accordance with JESD 51.
