MAX4899AEETE+

The MAX4899AEETE+ is a USB 2.0 high speed, fault-tolerant, 4:1 multiplexer in 16 pin TQFN package. This analogue multiplexer combines low on-capacitance (CON) and low on-resistance (RON) necessary for high performance switching applications. It features two digital inputs, C0 and C1, to control analogue signal path. Typical applications include switching a USB connector between USB and other operations such as serial communications, audio and video. An enable input (EN - complementary) is provided to disable all channels and place device into a high impedance (off) state as well as reducing power consumption. It operates from a 2.7V to 3.6V power supply voltage and protected against +5.5V shorts to COMA- and COMA+. In addition, COMA+ and COMA- are normally connected to outside circuitry and feature ±15kV ESD protection. It is used in cell phones, digital still cameras, PDAs, digital video cameras, MPEG-4 players, portable GPS, combination products and KVM.

• Low 4ohm (typ) on-resistance (RON)
• Operating temperature range from -40°C to 85°C
• 425MHz -3dB bandwidth
• Fault tolerant to meet full USB 2.0 specification
• Low operating current (200µA), ultra low quiescent current of 3.0µA (max) in standby mode
• Low threshold eliminates need for translators in 1.8V low voltage systems
• Crosstalk of -50dB at f = 50MHz

Applications
