28 Standards • Operates With 3-V to 5.
5-V VCC Supply • Operates up to 250 kbit/s • One Driver and One Receiver • Low Standby Current: 1 µA Typical • Accepts 5-V Logic Input With 3.
3-V Supply • Auto-Power-Down Feature Automatically Disables Drivers for Power Savings • Alternative High-Speed Device (1 Mbit/s) – SN75C3221E and SN65C3221E 2 Applications • Battery-Powered, Hand-Held, and Portable Equipment • Notebooks and Laptops • Mobile Phones and Wireless Devices 3 Description The MAX3221E is a single driver, single receiver RS232 solution operating from a single VCC supply.
The RS-232 pins provide IEC 61000-4-2 ESD protection.
The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.
The charge pump and four small external capacitors allow operation from a single 3-V to 5.
5-V supply.
These devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
Flexible control options for power management are available.
Auto-power down disables driver and charge pump when the receiver is disconnected or the remote driver is power down.
The drivers can be manually enabled or disabled.
INVALID output goes low when receiver input is unconnected or power off.
