Интерфейс RS-232 MAX561CAI+

EIA/TIA-562 приемопередатчик , 3В до 3.6В, SSOP-28

The MAX561CAI+ is a 3.3V transceiver with two EIA/TIA 562 receiver active in shutdown in 28 pin SSOP package. It operates with the 3V power supply at a 20Kbps data rate while maintaining 3.7V EIA/TIA 562 signal levels. The MAX561 include four line drivers, five receivers, a shutdown mode and a receiver enable input. An on-board charge pump voltage converter converters the 3.3V input to the 6.6V needed to comply with the EIA/TIA 562 output levels. The MAX561 has an active high shutdown and an active low receiver enable. In shutdown mode two receivers are in a high impedance three state mode. Each operate with four 1µF capacitors further reducing board space.

• Supply voltage range is 3V to 3.6V
• Operating temperature range from 0°C to 70°C
• Supply current is 5mA
• Shutdown supply current is 1µA
• Output enable time is 800ns and disable time is 500ns
• Three state TTL/CMOS receiver outputs
