... All RS-232 (and CMOS, SD, and EN for ADM3307E) inputs and outputs are protected against electrostatic discharges (up to ± 15 kV). This ensures compliance with IEC 1000-4-2 requirements. These devices are ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently being plugged/unplugged ...

... V using C5 as the storage element. However, it should be noted that, unlike other charge pump dc-to- dc converters, the charge pump on the ADM3307E does not run open-loop. The output voltage is regulated to ±7.25 V (or ±6.5 V for the ADM3310E and ADM3315E) by the Green Idle circuit and never reaches ± ...

... The shutdown function is intended to shut the device down, thereby minimizing the quiescent current. In shutdown, all transmitters are disabled. All receivers are shut down, except for receiver R3 (ADM3307E, ADM3312E, and ADM3315E), receiver R5 (ADM3311E), and receivers R4 and R5 (ADM3310E). Note that disabled transmitters are not three-stated in shutdown not permitted to connect multiple (RS-232) driver outputs together ...

... ADM3307E/ADM3310E/ADM3311E/ADM3312E/ADM3315E ESD TESTING (IEC 1000-4-2) IEC 1000-4-2 (previously 801-2) specifies compliance testing using two coupling methods, contact discharge and air-gap discharge. Contact discharge calls for a direct connection to the unit being tested. Air-gap discharge uses a higher test voltage but does not make direct contact with the unit under testing. With air discharge, the discharge gun is moved toward the unit under testing, which develops an arc across the air gap, thus the term air discharge ...
