× 8-bit RAM

PCF8583

10 LIMITING VALUES

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

11 HANDLING

Inputs and outputs are protected against electrostatic charge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS devices. Advice can be found in Data Handbook IC12

under

“Handling MOS Devices”.
