Five External Capacitors) (VCC = 5 V . . . Four External Capacitors) D Accepts 5-V Logic Input With 3.3-V Supply D Applications – RS-232 Interface – Battery-Powered Systems, PDAs – Notebook, Laptop, and Palmtop PCs – External Modems and Hand-Held Terminals D Packaged in Shrink Small-Outline Package description The SN75LV4737A‡ consists of three line drivers, five line receivers, and a charge-pump circuit. It provides the electrical interface between an asynchronous communication controller and the serial-port connector, and meets the requirements of TIA/EIA-232-F. This combination of drivers and receivers matches those needed for the typical serial port used in an IBM PC/AT or compatibles. The charge pump and five small external capacitors allow operation from a single 3.3-V supply, and four capacitors allow operation from a 5-V supply. The device has flexible control options for power management when the serial port is inactive. A common disable for all of the drivers and receivers is provided with the active-high STBY input. The active-low EN input is an enable for one receiver to implement a wake-up feature for the serial port. All the logic inputs can accept signals from controllers operating from a 5-V supply, even though the SN75LV4737A is operating from 3.3 V. The SN75LV4737A is characterized for operation over the temperature range of 0 °C to 70°C.
