Product data sheet

1. 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.

A low input voltage threshold allows pin Sn and E to be driven by lower level logic signals

without a 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.
