MAX4850/MAX4850H/MAX4852/MAX4852H 19-3375 Rev 0 7/04 Dual SPDT Analog Switches with Over-Rail Signal Handling General Description Features The MAX4850/MAX4850H/MAX4852/MAX4852H family USB 2.0 Full Speed (12MB) and USB 1.1 Signal of dual SPDT (single-pole/double-throw) switches oper- Switching Compliant ate from a single +2V to +5.5V supply and can handle Switch Signals Greater than V CC signals greater than the supply rail. These switches fea- ture low 3.5 or 3.5/7 on-resistance with low on- 0.1ns Differential Skew capacitance, making them ideal for switching audio 3.5/7 On-Resistance and data signals. 135MHz -3dB Bandwidth The MAX4850/MAX4850H are configured with two +2V to +5.5V Supply Range SPDT switches and feature two comparators for head- phone detection or mute/send key functions. The 1.8V Logic Compatible MAX4852 has two SPDT switches with no comparators Low Supply Current for low 1A supply current. 1A (MAX4852) For over-rail applications, these devices offer either the 5A (MAX4850) pass-through or high-impedance option. For the 10A (MAX4850H/MAX4852H) MAX4850/MAX4852, the signal (up to 5.5V) passes Available in a Space-Saving (3mm x 3mm), through the switch without distortion even when the posi- 16-Pin TQFN Package tive supply rail is exceeded. For the MAX4850H/ MAX4852H, the switch input becomes high impedance when the input signal exceeds the supply rail. The MAX4850/MAX4850H/MAX4852/MAX4852H are Ordering Information available in the space-saving (3mm x 3mm), 16-pin TQFN package and operate over the extended temper- TOP ature range of -40C to +85C.

Limit forward-diode current to maximum current rating. 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. ELECTRICAL CHARACTERISTICS (V = +2.7V to +5.5V, T = -40C to +85C, unless otherwise noted.
