• Manufacturer Part Number: LUCL8576BP-D
• Description: Dual Ringing SLIC
• Manufacturer: AGERE [Agere Systems]

L8576B Dual Ringing SLIC
Electrical Characteristics
Generally, 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. Minimum and
maximum values apply across the entire temperature range (0 °C to 70 °C) and entire battery range (to –72 V).
Unless otherwise specified, typical values are defined as 20 °C, V
into the device.
Table 3. Operating Conditions and Powering
1. Noncondensing.
2. The L8576B will operate below –24 V; –24 V is used for production test.
3. The termination impedance can be programmed up to 1200 ; 1000
4. This parameter is not tested in production. It is guaranteed by design and device characterization.
