SPECIFICATIONS

ELECTRICAL CHARACTERISTICS—5 V OPERATION

All typical specifications are at T_A= 25°C, V_DD1= V_DD2= 5 V. M inimum/maximum specifications apply over the entire recommended

operation range of 4.5 V ≤ V_DD1≤ 5.5 V, 4.5 V ≤ V_DD2≤ 5.5 V, and −40°C ≤ T_A≤ +125°C, unless otherwise noted. Switching specifications

are tested with C_L= 15 pF and CMOS signal levels, unless otherwise noted. Supply currents are specified with 50% duty cycle signals.
