Philips Semiconductors
Product specification
32 kHz watch circuits with adaptive motor
pulse
PCA146x series
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Note
1.
Connecting the battery with reversed polarity does not destroy the circuit, but in this condition a large current flows,
which will rapidly discharge the battery.
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
advisable to take handling precautions appropriate to handling MOS devices. Advice can be found in
“Data Handbook IC16, General, Handling MOS Devices”
