1 / 19 page February 2008 Rev 5 1/19 19 ST3232EB ST3232EC ± 15 kV ESD protection 3 to 5.5 V low power, up to 250 kbps, RS-232 drivers and receivers Features ■ ESD protection for RS-232 I/O pins ■ ±15 kV human body model ■ ±8 kV IEC 1000-4-2 contact discharge ■ 300 µA supply current ■ 250 kbps minimum guaranteed data rate ■ 6V/µs minimum guaranteed slew rate ■ Meet EIA/TIA-232 specifications down to 3 V ■ Available in SO-16, SO-16 large SSOP16 and TSSOP16 Description 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 four small 0.1 µF standard external capacitors for operations from 3 V supply. The ST3232E has two receivers and two drivers. The device is guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels. Typical applications are Notebook, Subnotebook and Palmtop Computers, Battery Powered Equipment, Hand-Held Equipment, Peripherals and Printers. SO-16 Large SSOP16 TSSOP16 SO-16 Table 1.
