Preliminary Information
MH88510/11
AC and DC Loop Electrical Characteristics*
*
AC and DC Loop 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.
x
The SLIC can be loaded with an AC impedance as low as 2200
without generating a false SHK output. Since each REN represents 8k
,
the SLIC can drive a REN of 3.6 without generating a false SHK output.
y
See section on Tip-Ring Drive Circuit for driving longer lines.
