match (0.5鈩?/div>
Max) higher dV/dt sensitivity (5000V/碌s), protection SCR
hold current set to 110mA.
The line break MOSFETs have very low on resistance
(<16.0鈩?Typ) and Ron match (<0.05鈩?Typ, 0.5鈩?Max) and a
blocking voltage >330V. The Ring Return MOSFET has a
typical Ron of 50鈩?and a blocking voltage >330V. The
Ringing Access switch is implemented with a SCR device
with a blocking voltage >480V. The SCR switch inherently
offers low EMI connect and disconnect circuitry. All control
I/Os use TTL thresholds making the device compatible with
3V logic.
The ISL5571A also includes on-chip protection in the form of
an over-voltage clamping circuit, current-limited MOSFET
switches, and thermal shutdown circuitry. The over-voltage
clamping circuit consists of a diode bridge and SCR.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
