Symbol Parameter Min Typ Max Unit Test Conditions Note 1: Input voltages may exceed supply voltages when input current is limited to 100 µA. 2: Dissipation rating assumes device is mounted with all leads soldered to PC board. 3: Refer to "Differential Input" discussion. 4: Backplane drive is in phase with segment drive for "OFF" segment and 180° out-of-phase for "ON" segment. Frequency is 20 times conversion rate. Average DC component is less than 50mV. 5: See "Typical Application". 6: A 48kHz oscillator increases current by 20 µA (typical). Common current not included. |
