Description

The DM20703ZE1 is a member of the ADM2xx family of line drivers/receivers. It is designed for EIA-232-E and V.28 communications interfaces. This model particularly caters to applications where the availability of ±12 V is limited. The ADM205, ADM206, ADM211, and ADM213 feature a low power shutdown mode, which reduces power dissipation making them perfect for use in battery-powered equipment. The ADM205 model is the only one among them that doesn't require any external components, making it an ideal choice where PCB space is a significant constraint. The ADM213 model features an active-low shutdown and an active-high receiver enable control, with two receivers remaining active during shutdown.

Application Scenarios

The DM20703ZE1 model is ideal for a wide range of applications that require strong communication interfaces. You can use this model to enhance the performance of the following:

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Comparison

• Low power consumption during normal usage.
• Low power shutdown mode feature reduces power dissipation to ≤5 μW.
• Does not require any external components i.e. useful for PCBs with significant constraints.
• Active receivers remain functional even during shutdown, useful for ring indicator monitoring.
• Plug-in upgrade available for MAX205-211/213 models.

• Designed for EIA-232-E and V.28 communication interfaces only.
• Output swing available is ±9 V only.
• Not suitable for applications requiring high data rate communication interfaces.
