Single low-ohmic 8-channel analog switch

Product data sheet

1. General description

The NX3L4051 is a low-ohmic 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 digital inputs makes the circuit tolerant to slower input rise and

fall times. Low threshold digital inputs allows this device to be driven by 1.8 V logic levels

in 3.3 V applications without significant increase in supply current ICC. This makes it

possible for the NX3L4051 to switch 4.3 V signals with a 1.8 V digital controller,

eliminating the need for logic level translation.The NX3L4051 allows signals with

amplitude up to VCC to be transmitted from Z to Yn or from Yn to Z. Its low ON resistance

(0.5 ï) and flatness (0.13 ï) ensures minimal attenuation and distortion of transmitted

signals.
