description
TheSN75C1406isalow-powerBiMOSdevicecontainingthreeindependentdriversandreceiversthatareused
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
theinputsignals. Ifthisisnotthecase, orforotheruses, itisrecommendedthattheSN75C1406receiveroutputs
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.

APPLICATION INFORMATION
The TIA/EIA-232-F specification is for data interchange between a host computer and a peripheral at signaling
rates up to 20 kbit/s. Many TIA/EIA-232-F devices will operate at higher data rates with lower capacitive loads
(short cables). For reliable operation at greater than 20 kbit/s, the designer needs to have control of both ends
of the cable. By mixing different types of TIA/EIA-232-F devices and cable lengths, errors can occur at higher
frequencies (above 20 kbit/s). When operating within the TIA/EIA-232-F requirements of less than 20 kbit/s and
with compliant line circuits, interoperability is assured. For applications operating above 20 kbit/s, the design
engineer should consider devices and system designs that meet the TIA/EIA-232-F requirements.
