ST3232B, ST3232C 3 to 5.5 V, low-power, up to 400 kbs RS-232 drivers and receivers Datasheet - production data 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, batterypowered equipment, hand-held equipment, peripherals, and printers. Table 1: Device summary 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 Order code Temp. range Package Packaging ST3232CDR 0 to 70 °C ST3232BDR -40 to 85 °C SO16 (tape and reel) 2500 parts per reel ST3232CWR 0 to 70 °C ST3232BWR -40 to 85 °C SO16L (tape and reel) 1000 parts per reel ST3232CTR 0 to 70 °C ST3232BTR -40 to 85 °C TSSOP16 (tape and reel) 2500 parts per reel 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.

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-. 4/18 DocID7454 Rev 12 ST3232B, ST3232C 3 Electrical characteristics Electrical characteristics Table 4: Electrical characteristics (C1 - C4 = 0.1 µF, VCC = 3 V to 5.5 V, TA = -40 to 85 °C, unless otherwise specified.
