Product specication
Threshold detector and reset generator
PCF1252-X family
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal handling precautions appropriate to handling MOS devices (see
“Handling MOS Devices”).
CHARACTERISTICS
VDD = 2.4 to 6.0 V; VSS =0V; Tamb = 40 to +85 °C; (see Fig.3); unless otherwise specied.
