MAX4996
PRODUCTIONTriple DPDT, Low-Capacitance Data Switches
Very Low On-Capacitance Data Switches Ideal for Multiplexing SDHC and SDIO Interfaces
Part Details
- Multiplex SD2.0/SDIO Interfaces
- Low Power Consumption (2µA max)
- +2.5V to +5.5V Supply Voltage Range
- Rail-to-Rail Signal Handling
- Low-Capacitance Switches, 6pF (typ)
- Low On-Resistance, 2Ω (typ)
- Excellent On-Resistance Flatness Over the Range of 0V to VCC
- Wide -3dB Bandwidth, 670MHz
- Small 24-Pin TQFN (3.5mm x 3.5mm)
The MAX4996/MAX4996L triple DPDT analog switches operate from a single +2.5V to +5.5V supply, and feature 2.0Ω (typ) on resistance, low 6pF (typ) on-capacitance, and low power-supply current consumption. The MAX4996/MAX4996L combine the low capacitance and low resistance necessary for high-frequency switching applications in portable electronics.
The MAX4996/MAX4996L have three logic inputs to control the switches in pairs. The MAX4996 has an active-high enable input (EN) to disable the switches, while the MAX4996L has an active-low enable input (active-low EN) to disable the switches. The enable input decreases the supply current and also places the COM_ outputs in a high-impedance state.
The MAX4996/MAX4996L feature a 5µA (max) supply-current consumption when the logic inputs are not rail-to-rail. This feature is especially valuable in applications where direct interface to low-voltage processors is necessary.
The MAX4996/MAX4996L are available in a space-saving 24-pin (3.5mm x 3.5mm) TQFN package and operate over the -40°C to +85°C temperature range.
