General Description

SC4 SC3 SC2 SC1

The e1467D is an integrated circuit in CMOS Silicon

Gate Technology for analog clocks. It consists of a

32-kHz oscillator, frequency divider, output pulse

formers, push-pull motor drivers and alarm output.

Integrated capacitors are mask-selectable to accomodate

the external quartz crystal. Additional capacitance can be

selected through pad bonding for trimming the oscillator

frequency.
