Product Overview
ST3222EBPR is a 3V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection to ±8kV using IEC1000-4-2 contact discharge and ±15KV using the human body model. It has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5V supplies with a dual charge pump. The charge pump requires only four small 0.1mF external capacitors for operation from 3V supply. This device has two receivers and two drivers. It features a 1mA 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 a 1mA supply current. It is used in applications such as notebooks, sub-notebook and palmtop computers, battery-powered equipment, hand-held equipment, peripherals, and printers.
- Meet EIA/TIA-232 specification down to 3V
- VCC power supply current is 0.3mA typical at (no load, SHDN = VCC, TA = 25°C)
- Shutdown supply current is 1µA typical at (no load, SHDN = VCC, TA = 25°C)
- Input leakage current is ±1µA maximum at (TA = 25°C)
- Output leakage current is ±25µA max at (VCC = 0 or 3V to 3.6V, VOUT = ±12V transmitters disable)
- Data transfer rate is 250Kbps minimum at (RL = 3Kohm, CL2= 1000pF one transmitter switching)
- Propagation delay input to output is 0.15µs typical at (RXIN to RXOUT, CL = 150pF)
- Transition slew rate is 30V/µs maximum at (C1 - C4 = 0.1µF, VCC = 3V to 5.5V, TA = -40°C to 85°C)
- Operating temperature range from -40°C to 85°C
- SSOP20 package
