Note 1: All voltage are with respect to the network ground terminal. 
Note 2: The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero.
Note 3: RS-232 pins are tested with respect to ground and each other.
Note 4: Per MIL-PRF-38535.
Note 5: RS-232 pins are tested with respect to ground.


Description

The UTC75185 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 UTC75185 is Characterized for operation over the temperature range of 0 to 70.
