description/ordering information

The SN65C3223 and SN75C3223 consist 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 devices provide 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 devices

operate at data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/µs to 150 V/µs

Flexible control options for power management are available when the serial port is inactive. The

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 µA.

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 µs. INVALID

is low (invalid data) if the receiver input voltage is between −0.3 V and 0.3 V for more than

30 µs. Refer to Figure 4 for receiver input levels.
