KEYPAD PROGRAMMABLE DIGITAL LOCKThe LS7222 is a programmable electronic lock imple-
mented in a 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. Input is provided by a matrix key-
pad whose maximum allowable size is 4 x 4. By LSI Computer Systems, Inc.
