PCA9306DCUT

Texas Instruments · Interface - Specialized · VSSOP-8

PCA9306DCUT from Texas Instruments, in a VSSOP-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 GND power_in Ground, 0V reference bias point for the device
2 VREF1 power_in Low-voltage reference supply input for SCL1 and SDA1, operating range 1.2V to (VREF2 - 0.6V)
3 SCL1 bidirectional Serial clock line on low-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode
4 SDA1 bidirectional Serial data line on low-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode
5 SDA2 bidirectional Serial data line on high-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode
6 SCL2 bidirectional Serial clock line on high-voltage side, open-drain I/O supporting 0V to 5.5V with internal clamping diode
7 VREF2 power_in High-voltage reference supply input for SCL2 and SDA2, operating range (VREF1 + 0.6V) to 5.5V
8 EN input Enable input for translation control; logic high enables bidirectional switching between sides with 3.5Ω ON-state resistance, logic low disables all I/O to high impedance
