3 V ESD-protected dual RS232 transceiver

29 August 2001 Telecoms, Datacoms, Wireless, IoT

Maxim has introduced the MAX3384E RS232 transceiver. For handheld equipment and accessories such as cellular phones, PDAs, and cradles, the MAX3384E contains two transmitters and two receivers that are protected to ±15 kV using IEC 1000-4-2 air gap discharge, ±8 kV using IEC 1000-4-2 contact discharge, and ±15 kV using the human body model.

A proprietary low-dropout transmitter output stage enables true RS232 performance over a full +3,0 to +5,5 V supply via a dual charge pump. The device features a shutdown mode in which the device consumes only 1 µA of supply current, and all transmitters and receivers are disabled, allowing these lines to be shared with other devices. The MAX3384E is guaranteed to run at a 250 Kbps data rate, and the charge pump requires only four small 0,1 µF capacitors.
