1/5/10Pcs TI SN75LV4737ADB Multichannel RS-232 Line Driver Transceiver SSOP-28

Description

1/5/10pcs TI SN75LV4737ADB Multichannel RS-232 Line Driver Transceiver 3-5.5V SSOP-28
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.
