The STLVDS31B is a quad differential line drivers that implements the electrical characteristics of low voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5 V differential standard levels (such as TIA/EIA-422B) to reduce the power, increase the switching speeds and allows operations with a 3.3 V supply rail. Any of the four current mode drivers will deliver a minimum differential output voltage magnitude of 247 mV into a 100 Ω load when enabled.

The ST26C32AB is a ST company's CMOS quad 3-state differential line receiver. It features low power consumption, ±0.2V sensitivity, typical propagation delay of 19ns, typical input hysteresis of 60mV, meets EIA standard RS-422, RS-423 requirements, and can be used to connect system buses.

The ST3222 is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements and high data-rate capabilities. ST3222 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 3.6 V power supplies. The device requires only four small 0.1 mF standard external capacitors for operating from 3 V supply. The ST3222 has two receivers and two drivers. The ST3222 features a 1 mA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers can remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1 mA supply current. The device is guaranteed to run at data rates of 250 Kbps while maintaining RS-232 output levels. Typical applications are notebooks, sub- notebooks and palmtop computers, battery powered equipment, hand-held equipment, peripherals and printers.
