Features
1. Description
The e1466D is an integrated circuit in CMOS Silicon Gate Technology for analog
clocks. It consists of a 32-kHz oscillator, frequency divider, output pulse formers and
push-pull motor drivers. Integrated capacitors are mask-selectable to accommodate
the external quartz crystal. Additional capacitance can be selected through pad bond-
ing for trimming the oscillator frequency.

... Absolute Maximum Ratings Absolute maximum ratings define parameter limits which, if exceeded, may permanently change or damage the device. All inputs and outputs on Atmel’s circuits are protected against electrostatic discharges. However, precautions to minimize the build-up of electrostatic charges during handling are recommended. The circuit is protected against supply voltage reversal for typically 5 minutes. ...
