General description

   The NX3L4051 is an 8-channel analog switch, suitable for use as an analog or digital multiplexer/demultiplexer. The NX3L4051 has three digital select inputs (S1 to S3), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). All eight switches share an enable input (E). A HIGH on E causes all switches into the high impedance OFF-state, independent of Sn. Schmitt trigger action at the select input (Sn and E) 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 (peak):

   ✦ 1.7 Ω (typical) at VCC = 1.4 V

   ✦ 1.0 Ω (typical) at VCC = 1.65 V

   ✦ 0.6 Ω (typical) at VCC = 2.3 V

   ✦ 0.5 Ω (typical) at VCC = 2.7 V

      0.5 Ω (typical) at VCC = 4.3 V

◾ Break-before-make switching

◾ High noise immunity

◾ ESD protection:

   ✦ HBM JESD22-A114F Class 3A exceeds 7500 V

   ✦ MM JESD22-A115-A exceeds 200 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
