DESCRIPTION
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.

FEATURES
• 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
    — VCCL (for logic system) : +3.0 to +5.5 V
    — VCCA (for LCD drive system) : +3.0 to +5.5 V
• Operating temperature : —30 to + 85 ßC
• Package : 264-pin TCP (Tape Carrier Package)
