Product data sheet
1. General description
The NX3L2T384 is a dual low-ohmic single-pole single-throw analog switch. Each switch
has two input/output terminals (nY and nZ) and an active LOW enable input (nE). When
pin nE is HIGH, the analog switch is turned off.
Schmitt trigger action at the enable input (nE) makes the circuit tolerant to slower input
rise and fall times. A low input voltage threshold allows pin nE to be driven by lower level
logic signals without a significant increase in supply current I_CC. This makes it possible for
the NX3L2T384 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need
for logic level translation.
The NX3L2T384 allows signals with amplitude up to V_CC to be transmitted from nY to nZ;
or from nZ to nY. Its low ON resistance (0.5 ) and flatness (0.13 ) ensures minimal
attenuation and distortion of transmitted signals.
