General description

The NX3DV2567 is a four-pole double-throw analog switch (4PDT) optimized for switching WLAN-SIM supply, data and control signals. It has one digital select input (S) and four switches each with two independent input/outputs (nY0 and nY1) and a common input/output (nZ). Schmitt trigger action at S makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 1.4 V to 4.3 V.

Features and benefits

■ Wide supply voltage range from 1.4 V to 4.3 V

■ Very low ON resistance for supply path:

◆ 0.5 Ω (typical) at VCC = 1.8 V

◆ 0.45 Ω (typical) at VCC = 2.7 V

■ Low ON resistance for data path:

◆ 7 Ω (typical) at VCC = 1.8 V

◆ 6 Ω (typical) at VCC = 2.7 V

■ Low ON capacitance for data path

■ Wide 3 db bandwidth > 160 MHz

■ Break-before-make switching

■ High noise immunity

■ ESD protection:

◆ HBM JESD22-A114F Class 3A exceeds 4000 V

◆ HBM JESD22-A114F Class 3A I/O to GND exceeds 7000 V

◆ CDM AEC-Q100-011 revision B exceeds 1000 V

■ CMOS low-power consumption

■ Latch-up performance exceeds 100 mA per JESD 78B Class II Level A

■ 1.8 V control logic at VCC = 3.6 V

■ Control input accepts voltages above supply voltage

■ Very low supply current, even when input is below VCC

■ High current handling capability (350 mA continuous current under 3.3 V supply for supply path switch)

■ Specified from -40 °C to +85 °C and from -40 °C to +125 °C

Applications

■ Cell phone, PDA, digital camera, printer and notebook
