ST202CTR

ST202B, ST202C 5 V powered multi-channel RS-232 drivers and receivers Datasheet - production data Description The ST202B, ST202C is a two-driver, tworeceiver device following EIA/TIA-232 and V.28 communication standards. It is particularly suitable for applications where ± 12 V is not available. The ST202B, ST202C uses a single 5 V power supply and only four external capacitors (0.1 µF). Typical applications are in: portable computers, low power modems, interface translation, and battery-powered RS-232 networks. Features Supply voltage range: 4.5 to 5.5 V Supply current no load (typ.): 1.5 mA Transmitter output voltage swing (typ): ± 9 V Transition slew rate (typ.): 12 V/µs Receiver propagation delay (typ.): 0.1 ms Compatible with MAX202 Receiver input voltage range: ± 30 V Data rate (typ.): 400 kbps/s Operating temperature range: -40 to 85 °C, 0 to 70 °C March 2017 DocID7313 Rev 9 This is information on a product in full production. 1/18 www.st.com Contents ST202B, ST202C Contents 1 Pinout information........................................................................... 3 2 Absolute maximum ratings............................................................. 4 3 4 Electrical characteristics ................................................................ 5 Typical application .......................................................................... 7 5 Typical performance characteristics ............................................. 8 6 Package information ....................................................................... 9 6.1 SO16 package information .............................................................. 10 6.2 SO16L package information ............................................................ 11 6.3 TSSOP16 package information ....................................................... 12 6.4 SO16 tape and reel package information ........................................ 13 6.5 SO16L tape and reel package information ...................................... 14 6.6 TSSOP16 tape and reel package information ................................. 15 7 Ordering information..................................................................... 16 8 Revision history ............................................................................ 17 2/18 DocID7313 Rev 9 ST202B, ST202C 1 Pinout information Pinout information Figure 1: Pin connections (top view) Table 1: Pin description Pin n° Symbol Name and function 1 C1 + Positive terminal for the first charge pump capacitor 2 V+ Doubled voltage terminal 3 C1 - Negative terminal for the first charge pump capacitor 4 C2 + Positive terminal for the second charge pump capacitor 5 C2 - Negative terminal for the second charge pump capacitor 6 V- Inverted voltage terminal 7 T2OUT 8 R2IN 9 R2OUT Second receiver output voltage 10 T2IN Second transmitter input voltage 11 T1IN First transmitter input voltage 12 R1OUT First receiver output voltage 13 R1IN 14 T1OUT First transmitter output voltage 15 GND Ground 16 VCC Supply voltage Second transmitter output voltage Second receiver input voltage First receiver input voltage DocID7313 Rev 9 3/18 Absolute maximum ratings 2 ST202B, ST202C Absolute maximum ratings Absolute maximum ratings are those values beyond which damage to the device may occur.
