Pin Description:
- VDD and VSS are power supply pins which are used to connect positive and negative of the power suppy respectively.
- OSC1 and OSC2 are used to connect external resistance for the internal oscillator. OSC1 is the oscillator input pin and OSC2 is the oscillator output pin.
- TE is used for enabling the transmission and is an active low input.
- A0 – A7 are the input address pins. By using these pins we can provide a security code for the data. These pins can be connected to VSS or left open.
Package Included:
1 x HT12E IC
