PI3C3306UEX

Diodes Incorporated · Analog Switches, Multiplexers · MSOP-8

PI3C3306UEX from Diodes Incorporated, in a MSOP-8. 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 /BE1 input Active-LOW switch enable for channel 1. Drive low to close the A1<->B1 FET switch; drive high to place A1/B1 into Hi-Z. TTL/CMOS input, tolerant to 3.6V regardless of VCC.
2 A1 passive Bus A, channel 1. Bidirectional pass-FET terminal connected to B1 when /BE1 is low; Hi-Z otherwise. ~5Ω on-resistance, high-bandwidth (>400 MHz), 5V tolerant.
3 B1 passive Bus B, channel 1. Bidirectional pass-FET terminal connected to A1 when /BE1 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant.
4 GND power_in Ground reference (0 V) for logic and switch bias.
5 A2 passive Bus A, channel 2. Bidirectional pass-FET terminal connected to B2 when /BE2 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant.
6 B2 passive Bus B, channel 2. Bidirectional pass-FET terminal connected to A2 when /BE2 is low; Hi-Z otherwise. ~5Ω on-resistance, 5V tolerant.
7 /BE2 input Active-LOW switch enable for channel 2. Drive low to close the A2<->B2 FET switch; drive high to place A2/B2 into Hi-Z. TTL/CMOS input, tolerant to 3.6V regardless of VCC.
8 VCC power_in Positive supply, 2.5V or 3.3V (±10%). Absolute max 4.6V to GND. Datasheet recommends applying VCC before driving signals on any I/O or control pin.
