Product Summary

The ST3222EBTR is a 15KV ESD-protected, 3 to 5.5V, low power, up to 250KBPS, RS-232 driver and receiver. The device has two receivers and two drivers. The ST3222EBTR features a 1µA 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 1µA supply current.

Parametrics

ST3222EBTR absolute maximum ratings: (1)supply voltage: -0.3 to 6V; (2)doubled voltage terminal: (VCC-0.3) to 7V; (3)transmitter input voltage range: -0.3 to 6V; (4)receiver input voltage range: ±25V; (5)transmitter output short to GND time: continuous.

Features

ST3222EBTR features: (1)ESD protectio for RS-232 I/O pins ±15kV human body model; (2)300μA supply current; (3)250Kbps minimum guarenteed data rate; (4)6V/μs minimum guaranteed slew rate; (5)meet EIA/TIA-232 specifications down to 3V; (6)available in SO-18, SSOP20 and TSSOP20.
