P DESCRIPTION
te The ST75C185 is ow power BICMOS device
le containing three independent drivers and five
o receivers that is used to interface data terminal
s equipment (DTE) with data circuit-terminating
b equipment (DCE). This device has been designed
O to conform to Standards ANSI/EIA-232-E. The
- drivers have a controlled output slew rate that is
t(s) limited to a maximum of 30V/µs and the receivers
have filters that reject input noise pulses that are
c shorter than 1µs. Both these features eliminate
u the need of external components.
d The ST75C185 hasn’t a power sequence fault
ro condition. It has been designed using low-power
P techniques in a BICMOS technology.
TSSOP
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.
