These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. TC7136 AND TC7136A ELECTRICAL SPECIFICATIONS Electrical Characteristics: VS =9V, fCLK =16kHz, and TA = +25°C, unless otherwise noted.

Ref. Temp. Coeff. = 0ppm/°C 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. |
