ST3232EB ST3232EC 15 kV ESD protection 3 to 5.5 V low power, up to 250 kbps, RS-232 drivers and receivers Datasheet - production data Hand-held equipment Peripherals and printers Description The ST3232E is a 3 V powered EIA/TIA-232 and SO-16 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. The ST3232E has a proprietary low- TSSOP16 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 F standard external Features capacitors for operations from 3 V supply. ESD protection for RS-232 I/O pins The ST3232E has two receivers and two drivers. 15 kV human body model The device is guaranteed to run at data rates of 8 kV IEC 1000-4-2 contact discharge 250 kbps while maintaining RS-232 output levels. 300 A supply current 250 kbps minimum guaranteed data rate 6 V/s minimum guaranteed slew rate Meet EIA/TIA-232 specifications down to 3 V Available in SO-16 and TSSOP16 Applications Notebook, subnotebook and palmtop computers Battery-powered equipment Table 1.
