DOUT2 9 16 DIN1 The TRSF3222E meets the requirements of 10 15 NC NC TIA/EIA-232-F and provides the electrical interface RIN2 11 14 DIN2 between an asynchronous communication controller 12 13 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 TRSF3222E operates at typical data signaling rates up to NC − No internal connection 1000 kbit/s and is an improved drop-in replacement for industry-popular '3222 two-driver, two-receiver functions. The TRSF3222E can be placed in the power-down mode by setting the power-down (PWRDOWN) input low, which draws only 1 μA 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 V , and V– is raised toward GND. Receiver outputs also can be placed in the CC high-impedance state by setting enable (EN) high.
