The ST3232E is a 3 V powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection to ± 8 kV using IEC1000-4-2 Contact Discharge and ± 15 kV using the Human Body Model. ST3232E has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5 V supplies with a dual charge pump. The charge pump requires only Table 1. The ST3232E has two receivers and two drivers. The device is guaranteed to run at data rates of 250Kbps while maintaining RS-232 output levels. Typical applications are Notebook, Subnotebook and Palmtop Computers, Battery Powered Equipment, Hand-Held Equipment, Peripherals and Printers.

Functional operation under these condition is not implied. Externally applied V+ and V- can have a maximum magnitude of +7 V, but their absolute addition can not exceed 13 V. Running on internal charge pump, intrinsic self limitation allows exceeding those values without any damage. Startup voltage sequence (VCC, then V+, then V-) is critical, therefore it is not recommended to use this device using externally applied voltage to V+ and V-. Figure 2.
