ORDERING INFORMATION

The TRS3223E 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 typical data signaling

rates up to 500 kbit/s and a maximum of 30-V/ μ s

driver output slew rate.

auto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode of

operation, if the device does not sense a valid RS-232 signal, the driver outputs are disabled. If FORCEOFF is

set low and EN is high, both drivers and receivers are shut off, and the supply current is reduced to 1 mA.

Disconnecting the serial port or turning off the peripheral drivers causes auto-powerdown to occur.

Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. With auto-powerdown enabled,

the device is activated automatically when a valid signal is applied to any receiver input. The INVALID output is

used to notify the user if an RS-232 signal is present at any receiver input. INVALID is high (valid data) if any

receiver input voltage is greater than 2.7 V or less than –2.7 V, or has been between –0.3 V and 0.3 V for less

than 30 μ s. INVALID is low (invalid data) if the receiver input voltage is between –0.3 V and 0.3 V for more than

30 μ s. Refer to Figure 4 for receiver input levels.
