LH1687

` Number of LCD drive outputs : 240
` Output circuit form : Push pull output
` Power save function : By setting the LCD drive output in a high-impedance condition, the current source of the LCD drive output circuit is cut off, which makes low power operation possible
` Sampling timing : Normal sampling operation and 3-point simultaneous sampling operation can be selected
`Video signal setting : Available for stripe pixel array panels and delta pixel array panels using mode setting circuit
` Sampling clock frequency :25 MHz (MAX.)
` Cascade connection
` Sampling sequence :Output shift direction can be selected OS1/OS240 or OS240/OS1
` Output amplitude voltage :
    4.8 Vp-p (at 5.0 V supply voltage)
` Supply voltages
    -  V_CCL (for logic system) : +3.0 to +5.5 V
    - V_CCA (for LCD drive system) : +3.0 to +5.5 V
` Operating temperature : Ð30 to + 85 ûC
` Package : 264-pin TCP (Tape Carrier Package)

When connecting or disconnecting the power supply, this IC must be used within the range of the absolute maximum ratings.

The LH1687 is a 240-output TFT-LCD source driver IC used in such products as TV sets. The LH1687 samples and holds three video signals of R, G and B by sample and hold circuits synchronized with the CK, and simultaneously outputs the LCD drive voltage from all output pins.
