Description

The MAX3243CDW consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV ESD (HBM) protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. This combination of drivers and receivers matches that needed for the typical serial port used in an IBM PC/AT, or compatible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. In addition, the device includes an always-active noninverting output (ROUT2B), which allows applications using the ring indicator to transmit data while the device is powered down.The device operates at data signaling rates up to 250 kbit/s and a maximum of 30-V/μs driver output slew rate. MAX3243CDW Features • Single-Chip and Single-Supply Interface for IBM PC/AT Serial Port• RS-232 Bus-Pin ESD Protection Exceeds ±15 kV Using Human-Body Model (HBM)• Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards• Operates With 3-V to 5.5-V VCC Supply• Three Drivers and Five Receivers• Operates Up To 250 kbit/s• Designed to Transmit at a Data Rate of 250 kbit/s• Low Standby Current . . . 1 μA Typical• External Capacitors . . . 4 × 0.1 μF• Accepts 5-V Logic Input With 3.3-V Supply• Always-Active Noninverting Receiver Output(ROUT2B)
