PI3CH480QEX

Diodes Incorporated · Signal Switches / Encoders & Decoders / Multiplexers · QSOP-16-150mil

PI3CH480QEX from Diodes Incorporated, in a QSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S input Select input. Chooses which of the two data inputs (I0 or I1) is routed to each Y output when /EN is low. S=L selects I0, S=H selects I1.
2 IA0 bidirectional Channel A data input 0. Bidirectional analog/digital switch pin; connects to YA when S=L and /EN=L. Signal range beyond rail-to-rail (0 to 5 V with 3.3 V VCC).
3 IA1 bidirectional Channel A data input 1. Bidirectional switch pin; connects to YA when S=H and /EN=L.
4 YA bidirectional Channel A common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IA0 or IA1 via ~5 Ω switch depending on S.
5 IB0 bidirectional Channel B data input 0. Bidirectional switch pin; connects to YB when S=L and /EN=L.
6 IB1 bidirectional Channel B data input 1. Bidirectional switch pin; connects to YB when S=H and /EN=L.
7 YB bidirectional Channel B common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IB0 or IB1 via ~5 Ω switch depending on S.
8 GND power_in Ground reference for the device.
9 YC bidirectional Channel C common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IC0 or IC1 via ~5 Ω switch depending on S.
10 IC1 bidirectional Channel C data input 1. Bidirectional switch pin; connects to YC when S=H and /EN=L.
11 IC0 bidirectional Channel C data input 0. Bidirectional switch pin; connects to YC when S=L and /EN=L.
12 YD bidirectional Channel D common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to ID0 or ID1 via ~5 Ω switch depending on S.
13 ID1 bidirectional Channel D data input 1. Bidirectional switch pin; connects to YD when S=H and /EN=L.
14 ID0 bidirectional Channel D data input 0. Bidirectional switch pin; connects to YD when S=L and /EN=L.
15 /EN input Active-low enable input. When high, all Y outputs are placed in high-impedance (Hi-Z / disabled) state. When low, the mux passes signals per the S select input.
16 VCC power_in Supply voltage input. Operates at 1.8 V ±10%, 2.5 V ±10%, or 3.3 V ±10%. ICC quiescent current 0.2-0.8 mA typ depending on supply.
