L8574D Resistive Subscriber Line Interface Circuit (SLIC), Ring

Electrical Characteristics

In general, minimum and maximum values are testing requirements. However, some parameters may not be

tested in production because they are guaranteed by design and device characterization. Typical values reflect

the design center or nominal value of the parameter; they are for information only and are not a requirement. Mini-

mum and maximum values apply across the entire temperature range (–40

°C to +85 °C) and entire battery range

(–35 V to –60 V). Unless otherwise specified, typical is defined as 25

–48 V. Positive currents flow into the device.

Table 2. Operating Conditions and Powering

1. Not to exceed 26 grams of water per kilogram of dry air.

2. Includes current in all external resistors per Figure 15.

3. This parameter is not tested in production. It is guaranteed by design and device characterization.
