This is just a simple IR remote control unit. The PIC16F616 generates a 38MHz signal, the BAUD is 2400, and the IR LED is a model#TSAL5300 powered by a CR2025 3v lithium battery.
As you can see the two transistors (2N2222) create a AND gate which modulates the UART signal.
Considering this is a battery powered application, the goal is battery life. Is the choice of using two transistors a good one? Should I go with an actual AND gate such as https://www.electro-tech-online.com/custompdfs/2010/03/NL27WZ08-DPDF.pdf
Thanks.
