STMicroelectronics
Description
The ST3222E is a 3 V 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 ± 8 kV using IEC1000-4-2 Contact Discharge and ±15 kV using the Human Body Model. ST3222E has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5 V supplies with a dual charge pump. The charge pump requires only four small 0.1 mF external capacitors for operation form 3 V supply.
Features
■ ESD protection for RS-232 I/O pins ± 15 kV
human body model, ± 8 kV IEC 1000-4-2
contact discharge
■ 300 µA supply current
■ 250KBps minimum guarantee data rate
■ 6 V/µs minimum guarantee slew rate
■ Meet EIA/TIA-232 specification down to 3 V
■ Available in SSOP20 and TSSOP20
