Интерфейс RS-232 MAX221CAE+

Приемопередатчик RS232 , 4.5В-5.5В питание, 1 драйвер, SSOP-16

The MAX221CAE+ is a +5V powered single RS232 transceiver with AutoShutdown in 16 pin SSOP package. This RS232 transmit/receive and V.28 communication interface device has automatic shutdown/wake-up features and high data rate capabilities. The MAX221 achieves a low 1µA supply current with Maxim's revolutionary AutoShutdown feature. AutoShutdown saves power without changes to existing BIOS or operating system by entering low power shutdown mode when RS232 cable is disconnected or when transmitter of connected peripheral is off. The device wakes up and drives INVALID (complementary) pin high when an active RS232 cable is connected. The internal power supply consists of a dual charge pump that provides positive output voltage (doubling charge pump) and negative voltage (inverting charge pump) from a single +5V supply.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range from 0°C to 70°C
• Maximum data rate of 250Kbps
• VCC supply current of 5mA
• Transmitter skew of 200ns and receiver skew of 50ns
• Transition region slew rate of 6V
• µs
