2 / 12 page  3-172 TELCOM SEMICONDUCTOR, INC. ABSOLUTE MAXIMUM RATINGS* Supply Voltage (V+ to V–) ............................................ 15V Analog Input Voltage (either input)(1) ................... V+ to V– Power Dissipation (TA ≤ 70°C) 64-Pin Flat Package ......................................... 1.14W Operating Temperature ‘C’ Devices ............................................. 0 °C to +70°C Storage Temperature ............................ – 65 °C to +150°C Lead Temperature (Soldering, 10 sec) ................. +300 °C *Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under Absolute Maximum Ratings may cause perma- nent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS: unless otherwise stated VS = 9V; ROSC = 430 kΩ; TA = 25°C; Full–Scale = 20 mV.

Input voltages may exceed the supply voltages when the input current is limited to 100 µA. 2. Static sensitive device. Unused devices should be stored in conductive material to protect devices from static discharge and static fields. 3. Backplane drive is in phase with segment drive for ‘off’ segment and 180 °C out of phase for ‘on’ segment. Frequency is 10 times conversion rate. 4. Logic input pins 58, 59, and 60 should be connected through 1M Ω series resistors to VSS for logic 0. TC826 A/D CONVERTER WITH BAR GRAPH DISPLAY OUTPUT |
