High-Bandwidth, T1/E1, SPST Analog Switches  
General Description  
Features  
Quad-SPST NO, NC, and NC/NO Configurations  
Dual-Supply Operation from ±±3±ꢀ to ±ꢁꢀ  
Single-Supply Operation from +6ꢀ to +11ꢀ  
The MAX4815/MAX4816/MAX4817 high-bandwidth,  
low-on-resistance, quad-SPST analog switches are  
designed to serve as integrated T1/E1 protection  
switches for 1+1 and N+1 line-card redundancy appli-  
cations. Each MAX4815/MAX4816/MAX4817 replaces  
four electromechanical relays, significantly reducing  
board space, simplifying PC board routing, and reduc-  
ing power consumption. These devices operate with  
±±.±3 or ±53 dual supplies for applications requiring  
T1/E1 signal switching in the line side of the interface  
transformer. Internal voltage multipliers drive the analog  
switches, yielding excellent linearity and low ±.7Ω typi-  
cal on-resistance within the T1/E1 analog signal range.  
This high-bandwidth (550MHz typical) family of prod-  
ucts is optimized for low return loss and matched pulse  
template performance in T1/E1 long-haul and short-haul  
applications.  
Hot Insertion Tolerant with No DC Path to the  
Supplies  
Low On-Resistance, R  
= ±37Ω (typ) and 6Ω

(max)  
Over ꢁꢁ0MHz, -±dB Signal Bandwidth  
Excellent Crosstalk and Off-Isolation Performance  
Over the T1/E1 Signal Spectrum: 110dB Crosstalk  
Attenuation at 1MHz  
Low Current Consumption of 2mA (max)  
-40°C to +8ꢁ°C Extended Temperature Range  
Space-Saving, 16-Pin, ꢁmm x ꢁmm Thin QFN  
The MAX4815/MAX4816/MAX4817 are available in a  
tiny 16-pin, 5mm x 5mm, thin QFN package and are  
specified over the extended -40°C to +85°C tempera-  
ture range.
