Application:

• Used for converting Parallel to serial data.
• Wireless communication application involving RF.
• Used in Home automation for remote switching.
• Burglars alarm system, Fire alarm, etc.
• Garage doors, Car alarm system, Car door controls, etc.

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
