UTC75185

LINEAR INTEGRATED CIRCUIT

QW-R113-003,B

MULTIPLE RS-232 DRIVERS AND

RECEIVERS

DESCRIPTION

The UTC 75185 complies with the requirements of the

TIA/EIA232-F and ITU (formerly CCITT) v.28 standards.

These standards are for data interchange between a host

computer and peripheral at signaling rates up to 20kbit/s.

The switching speeds of the UTC 75185 are fast enough

to support rates up to 120kbite/s with lower capacitive

loads (shorter cables). Interoperability at the higher

signaling rates cannot be assured unless the designer

has design control of the cable and the interface circuits

at both ends. For interoperability at signaling rates to

120kbit/s, use of

ITA/EIA-423-B

(ITU

v.10) and

TIA/EIA-422-B (ITU v.11) standards are recommended.

The UTC 75185 is Characterized for operation over

the temperature range of 0

°C to 70°C.
