Integrated T1/E1/J1 Short-Haul and Long-Haul Protection Switches
General Description
The MAX4670 is an integrated T1/E1/J1 analog protec-
tion switch for 1+1 and N+1 line-card redundancy
applications. It protects two T1/E1/J1 ports by combin-
ing eight SPDT switches in a single package. The
switch is optimized for high-return loss and pulse-tem-
plate performance in T1/E1/J1 long-haul and short-haul
applications. The part offers built-in chip-side surge
protection capability for short-haul intrabuilding appli-
cations.
The MAX4670 replaces two diode arrays or two tran-
sient voltage suppressors (TVSs) and four dual-SPDT
relays, significantly reducing board space and simplify-
ing PC board routing. The MAX4670 pinout is targeted
for T1/E1/J1 applications, resulting in a simplified layout
when interfacing with standard line transformers and
line interface units (LIUs).
The MAX4670 has four 1.0Ω(max) on-resistance switch-
es with 60pF/40pF on-/off-capacitances for interfacing to
the LIU transmitter outputs. The MAX4670 also includes
four 10Ω(max) on-resistance switches with low
24pF/12pF on-/off-capacitances for interfacing to the LIU
receiver inputs. Four logic inputs control the receive/
transmit pairs, in addition to a SWITCHinput that con-
nects all switches to the system’s protection bus.
The MAX4670 operates from a single +2.7V to +3.6V
supply and is available in 32-pin thermally enhanced
TQFN package. The MAX4670 is specified over the
-40°C to +85°C operating temperature range.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
