Description
General part information
TRS3222 Series
The TRS3222 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). 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. The device operates at data signaling rates up to 250 kbit/s and a maximum of 30-V/µ s driver output slew rate.
The TRS3222 can be placed in the power-down mode by settingPWRDOWNlow, which draws only 1 µ A from the power supply. When the device is powered down, the receivers remain active while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is disabled; V+ is lowered to VCC, and V- is raised toward GND. Receiver outputs also can be placed in the high-impedance state by settingENhigh.
