MAX4818/MAX4819
High-Bandwidth T1/E1 Dual-SPDT Switches/
4:1 Muxes
______________________________________________________________________________________

Detailed Description
The MAX4818/MAX4819 are each a high-bandwidth,
low-on-resistance dual-SPDT analog switch/4:1 multi-
plexer, respectively. Both the MAX4818 and the
MAX4819 are designed to serve as integrated T1/E1
analog protection switches for 1+1 and N+1 line-card
redundancy applications. These devices replace
electromechanical relays to save board space, reduce
power consumption, and simplify PC board routing.
The MAX4818/ MAX4819 allow the user to live insert the
boards with no adverse effects.
The MAX4818/MAX4819 operate from ±3.3V or ±5V
dual supplies, which are required for E1/T1 signal
switching in the line-side of the interface transformer.
Internal voltage multipliers supply the switches yielding
excellent linearity and low on-resistance, typically 4
within the E1/T1 analog signal range. This high-band-
width family of devices is optimized for low return loss
and matched pulse template performance in E1/T1
short-haul and long-haul applications.
Logic Inputs
The MAX4818 has four digital control inputs: EN, SET,
IN1, and IN2. The EN input enables the switches. A logic
1 on SET connects COM to the NO_ terminal. IN_ con-
trols the switch when SET is low, as shown in Table 1.
The MAX4819 has four digital control inputs: EN, SET,
A1, and A0. The EN input enables the multiplexer. A
logic 1 on SET connects all NO_ to COM. A1 and A0
control which terminal will be connected to COM when
SET is low, as shown in Table 2.
Analog Signal Levels
The on-resistance of the MAX4818/MAX4819 is very low
and stable as the analog signals are swept from V- to V+
(see the Typical Operating Characteristics).
