DESCRIPTION
The ST75C185 is ow power BICMOS device
containing three independent drivers and five
receivers that is used to interface data terminal
equipment (DTE) with data circuit-terminating
equipment (DCE). This device has been designed
to conform to Standards ANSI/EIA-232-E. The
drivers have a controlled output slew rate that is
limited to a maximum of 30V/碌s and the receivers
have filters that reject input noise pulses that are
shorter than 1碌s. Both these features eliminate
the need of external components.
The ST75C185 hasn鈥檛 a power sequence fault
condition. It has been designed using low-power
techniques in a BICMOS technology.

In most application the receivers contained in this
device will interface to single inputs 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 ST75C185 receiver outputs be buffered by
single gates of the HCMOS, ALS or 74F logic
families.
