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.
DC Characteristics
VDD = VIN = 5V, TA = TJ = 25°C, COSC = 1.2nF, unless otherwise specified.
