MH88435-P

Preliminary Information

2-46

.

*Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.

‡ Typical figures are at 25˚C 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

Ω leakage Tip/Ring to Ground. For countries requiring 100MΩ 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.
