Product Description

STMicroelectronics ST3222BTR is a 2-channel line transceiver designed for EIA/TIA-232 and V.28/V.24 communication interfaces, powered by a low 3 V supply with CMOS/TTL logic compatibility. It operates efficiently in portable and handheld devices, extending battery life through a low power 1 mA shutdown mode while allowing receiver activity for monitoring modems.

This line transceiver features a proprietary low dropout transmitter output stage, ensuring true RS-232 performance at supply voltages from 3 to 3.6 V. The device supports a minimum guaranteed data transfer rate of 250 kbps and slew rate of 6 V/µs, suitable for high-speed serial communication.

The ST3222BTR is housed in a compact 20-pin TSSOP surface mount package, measuring 6.6 mm in length, 4.48 mm in width, and 1.2 mm in height, making it ideal for space-constrained electronic designs. The operating temperature range of -40°C to 85°C ensures reliable performance in harsh environments.

The device requires only four small 0.1 µF capacitors for complete operation from a 3 V supply, simplifying external component requirements. With a supply current of 1 mA and output current characteristics of -1 mA (high level) and 1.6 mA (low level), it meets the demands of modern battery-powered systems.

Typical industrial applications include integration in notebooks, sub-notebooks, palmtop computers, handheld devices, peripherals, and printers requiring reliable serial communication.

The device operates efficiently with low power consumption suitable for portable equipment. Guarantees RS-232 performance with a data rate of 250 kbps. Compact TSSOP 20-pin package ideal for surface mounting in space-constrained applications.

Wide operating temperature range for industrial and commercial uses. Simple external capacitor configuration enhances ease of integration. Explore more products in the Interface ICs category at EnvMart for diverse semiconductor solutions.
