Description: | 3-V TO 5.5-V MULTICHANNEL RS-232 LINE DRIVERS/RECEIVERS WITH ??15-kV ESD PROTECTION |
Manufacturer: | Texas Instruments |
Datasheet: | PDF (227K). Click here to download *) |
The SN65C3222E and SN75C3222E 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 meet the requirements of TIA/EIA-232-F and 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 typical data signaling rates up to 1000 kbit/s and are improved drop-in replacements for industry-popular '3222 two-driver, two-receiver functions. |
