Product specification

4-digit duplex LCD car clock

PCF1179C

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

Note

1. Connecting the supply voltage with reverse polarity, will not harm the circuit, provided the current is limited to 10 mA

by an external resistor.

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”.
