ST202EC中文资料15KV ESD保护5V RS-232收发器，温度范围[0℃, 70℃]数据手册ST规格书

描述 Description

The ST202EB, ST202EC, ST232EB, and ST232EC are two-driver, two-receiver devices designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ± 15 kV electrostatic discharge (ESD) shocks. The drivers meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 230 kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST202EB, ST202EC, ST232EB, and ST232EC use a single 5 V supply voltage.

The ST232EB and ST232EC operate with four 1 µF capacitors, while the ST202EB and ST202EC operate with four 0.1 µF capacitors, further reducing cost and board space.

特性 Features

• ESD protection for RS-232 I/O pins: ± 15 kV human body model
• Guaranteed 230 kbps date rate
• Guaranteed slew rate range 3 to 30 V/µs
• Operates from a single 5 V power supply
