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.
