Hello guys, i am currently searching for a transistor array with 10+ transistor to minimize the usage of single transistors, my design need 20 PNP to drive the gate of N-MOS, i could only find quad arrays so i don't know if anyone know an IC with more than that.

the collector of those PNP is connected to the base of the N-MOS in the second image.

the purpose of using NPN is because the PWM expander work as sink only output.

thanks in advance

 

What are the needed electrical specifications?

 

Try udn2981.

 

Why are you going about it in such a complex way?
Firstly, if you accept that the logic is reversed, will the LED driver not drive the transistors directly, with just a pull-up resistor?
Secondly, why not use an LED driver that is intended to drive external transistors, such as PCA9685?
Thirdly, why not use a I2C output expander such as PCF8575 or MCP23017?
Fourthly, why not use logic gates to invert the logic such as 74HC04 or 74Hc540?
