SLLSET7C – MAY 2016 – REVISED MAY 2016 TRS3122E 1.8 V Low Power Dual RS-232 Transceiver
1 Features 3 Description The TRS3122E is a two-driver and two-receiver RS232 interface device, with split supply pins for mixedvoltage operation. All RS-232 inputs and outputs are
protected to В±15 kV using the IEC 61000-4-2 Air-Gap
Discharge method, В±8 kV using the IEC 61000-4-2
Contact Discharge method, and В±15 kV using the
Human-Body Model. 1 Extended VCC operating nodes: 1.8 V, 3.3 V, or
5.0 V
– Unique Tripler Charge Pump Architecture
Enables Low VCC of 1.8V While Maintaining
Compatibility with 3.3 V and 5 V Supplies
Integrated Level-Shifting Functionality Eliminates
the Need for External Power or Additional Level
Shifter While Interfacing with Low-Voltage MCUs
Enhanced ESD Protection on RIN Inputs and
DOUT Outputs
