TSL1014 14 + 1 channel buffers for TFT-LCD panels Datasheet production data Features Wide supply voltage: 5.5 V to 16.8 V Low operating current: 6 mA typical at 25 C Gain bandwidth product: 1 MHz High current COM amplifier: 100 mA output current Industrial temperature range: -40 C to +85 C 7 x 7 mm TQFP48 Small package: TQFP48 Automotive qualification Pin connections (top view) Application TFT liquid crystal display (LCD) Description The TSL1014 device is composed of 14 + 1 channel buffers which are used to buffer the reference voltage for gamma correction in thin film transistor (TFT) liquid crystal displays (LCD). One COM amplifier is able to deliver high output current value, up to 100 mA. Amplifiers A and B feature positive single supply inputs for common mode voltage behavior. The amplifiers C to N inclusive, and the COM amplifier, feature negative single supply inputs and are dedicated to the highest and lowest gamma voltages. The TSL1014 device is fully characterized and guaranteed over a wide industrial temperature range (-40 to +85 C).

Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kW resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 3. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 W). This is done for all couples of connected pin combinations while the other pins are floating. 4. Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground through only one pin. Table 2.
