4 / 12 page 1998 Apr 03 4 Philips Semiconductors Product specification 32 kHz watch circuits using a silver-oxide or a 3 V lithium battery PCA167x 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”. CHARACTERISTICS VDD = 1.55 V; VSS =0V; fosc = 32.768 kHz; Tamb =25 °C; crystal: RS =20kΩ; C1 = 2 to 3 fF; CL = 8 to 10 pF; C0 = 1 to 3 pF; unless otherwise specified. SYMBOL PARAMETER CONDITIONS MIN.
