5 / 16 page  1998 Apr 16 5 Philips Semiconductors Product specification Threshold detector and reset generator PCF1252-X family Notes 1. Long time stability of COMIN switch point VSP and voltage trip point VTRIP: within 10 years of continuous operation at VDD(max) and an average operating temperature of 55 °C the drift of VSP will not exceed ±10 mV. The maximum drift for VTRIP will not exceed (±VTRIP(typ)/VSP(typ)) 10 mV. 2. Values given per degree Kelvin; tested on a sample basis. 3. Conformance to these specifications is only guaranteed if the slew rate of VDD is less than 25 V/ms.
