Totally Lead-Free & Fully RoHS Compliant (Notes 1
& 2)
The PI3A27518Q is a 6-channel, 1:2 multiplexer / de-
multiplexer. The COMx port can be configured to con-
nect with NOx or NCx ports in 4 different modes (refer
to Truth Table for details)
The PI3A27518Q has a wide operating voltage range,
very low power consumption and small packaging.
It can be used as an analog switch or as a low-delay bus
switch. Specified over a wide operating power supply
voltage, 1.65V to 3.6V, the PI3A27518Q has an On-
Resistance of 5Ω at +3.3V.
Break-before-make switching prevents both switches be-
ing enabled simultaneously. This eliminates signal disrup-
tion during switching.
Halogen and Antimony Free. “Green” Device (Note 3)
The DIODES™ PI3A27518Q is suitable for automo-
tive applications requiring specific change control;
this part is AEC-Q100 qualified, PPAP capable, and
manufactured in IATF 16949 certified facilities.
