Product overview

Description

The ST3232B and ST3232C devices are 3 V powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements and high data-rate capabilities. These devices have a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5.5 V supplies. The devices require only four small 0.1 mF standard external capacitors for operation from a 3 V supply.
The ST3232B and ST3232C have two receivers and two drivers.
The devices are guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels. Typical applications are notebooks, subnotebooks and palmtop computers, battery-powered equipment, hand-held equipment, peripherals, and printers.
  • All features

    • 300 µA supply current
    • 300 kbps minimum guaranteed data rate
    • 6 V/µs minimum guaranteed slew rate
    • Meets EIA/TIA-232 specifications down to 3 V
    • Available in SO16, SO16L, and TSSOP16 packages
