DC Electrical Characteristics
Unless stated otherwise, VDD = 5V, ±10%, Ambient Temperature 0 to +70
° C
Note 1: Pins X1 and X2 each have 34 pF capacitance. When used with a crystal, the total combined
capacitance as seen by the crystal is 17 pF. If driving X1 with a clock input, the load capacitance will be
34 pF.
AC Electrical Characteristics
Unless stated otherwise, VDD = 5V±10%, Ambient Temperature 0 to +70
° C, CL=15pf
Note 1: Measured with 15pF load
