NX3L4684
Low-ohmic dual single-pole double-throw analog switch
Rev. 8 — 3 April 2014
Product data sheet
1. General description
The NX3L4684 is a dual low-ohmic single-pole double-throw analog switch, suitable for
use as an analog or digital multiplexer/demultiplexer. Each switch has a digital select input
(nS), two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ).
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 NX3L4684 to switch 4.3 V signals with a 1.8 V digital controller,
eliminating the need for logic level translation. The NX3L4684 allows signals with
amplitude up to VCC to be transmitted from nZ to nY0 or nY1; or from nY0 or nY1 to nZ. Its
low ON resistance (0.3 for Y0 port, 0.5 for Y1 port) and flatness (0.1 ) ensures
minimal attenuation and distortion of transmitted signals.
2. Features and benefits
Wide supply voltage range from 1.4 V to 4.3 V
Very low ON resistance (peak) for Y0 port:
0.8 (typical) at VCC = 1.4 V
0.5 (typical) at VCC = 1.65 V
0.3 (typical) at VCC = 2.3 V
0.25 (typical) at VCC = 2.7 V
0.25 (typical) at VCC = 4.3 V
Break-before-make switching
High noise immunity
ESD protection:
HBM JESD22-A114F Class 3A exceeds 4000 V
MM JESD22-A115-A exceeds 200 V
CDM AEC-Q100-011 revision B exceeds 1000 V
IEC61000-4-2 contact discharge exceeds 6000 V for switch ports
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)
Specified from 40 C to +85 C and from 40 C to +125 C
