Electrical Engineering

I am using an IR transceiver in my design.This IC is working at 3.3V supply.This IC need not be on always so I decided to give a control to it's shut down pin (Pin no 5,Shutdown Input. Active low).A transistor switch is used for this purpose.When the switch is ON the transceiver will be active and when it is off the transceiver shutdown pin will be connected to 3.3V. My circuit is given below.The value of R1 is 10K.

The base control signal is coming from a Microcontroller.The uC is also working at 3.3V
