Important Note:
All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at the
specified temperature and are pulsed tests, therefore: TJ = TC = TA.
Electrical Characteristics
VDD = VIN = 5V, COSC = 1nF, CSLOPE = 470pF, TA = 25°C unless otherwise specified.
