LS7222 - KEYPAD PROGRAMMABLE DIGITAL LOCK

Description

The LS7222 is a programmable electronic lock implemented in a monolithic CMOS integrated circuit.

The circuit contains all the necessary memory, decoder and control logic to make a programmable "keyless" lock system to control electro-mechanical locks.

Features

  • Stand alone lock logic.
  • 38416, 4-digit combinations.
  • 3 different user programmable codes.
  • Momentary and static lock control outputs.
  • Internal key debounce circuitry.
  • Tamper detection output.
  • Status outputs.
  • Low current consumption.
  • +4V to +15V operation (VDD -Vss).
  • LS7222 (DIP), LS7222-S (SOIC)- See Figure 1.
