Preliminary Information
2-46
.
*Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Typical figures are at 25C with nominal +5V supply and are for design aid only
Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
Typical figures are at 25
°
C with nominal + 5V supplies and are for design aid only.
Note 1: Refer to EIA/TIA 464 section 4.1.1.4.4.
Note 2: This is equivalent to 10M
leakage Tip/Ring to Ground. For countries requiring 100M
leakage use the MH88436 with an
enhanced leakage specification.
Note 3: Operation at low loop currents depends on the DC programming resistor between VLoop1/2. The recommended 360K value
will support V34 operation down to 20mA. Voice operation is supported down to 15mA.
Absolute Maximum Ratings* -
All voltages are with respect to AGND unless otherwise specified.
