description

The SN75154 is a monolithic low-power Schottky line receiver designed to satisfy the requirements of the

standard interface between data terminal equipment and data communication equipment as defined by ANSI

Standard EIA/TIA-232-E. Other applications are for relatively short, single-line, point-to-point data transmission

and for level translators. Operation is normally from a single 5-V supply; however, a built-in option allows

operation from a 12-V supply without the use of additional components. The output is compatible with most TTL

circuits when either supply voltage is used.

the positive-going and negative-going threshold voltages. See typical characteristics. In this mode of operation,

if the input voltage goes to zero, the output voltage will remain at the low or high level as determined by the

previous input.

For fail-safe operation, the threshold-control terminals are open. This reduces the hysteresis loop by causing

the negative-going threshold voltage to be above zero. The positive-going threshold voltage remains above

zero as it is unaffected by the disposition of the threshold terminals. In the fail-safe mode, if the input voltage

goes to zero or an open-circuit condition, the output will go to the high level regardless of the previous input

condition.

The SN75154 is characterized for operation from 0

°C to 70°C.
