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.
