This LSI consists of 80-bit latches I and II, 80-bit level shifter, and 80-bit 4-level driver. It latches the 4-bit parallel display data from the LCD controller LSI or microcontroller, and then outputs the signal for the LCD driving. FEATURES • Logic supply voltage : 2.7V to 5.5V • LCD driving voltage : 14V to 28V • Applicable LCD duty : 1/64 to 1/256 • Bias voltage can be supplied externally • LCD output : 80 • 4-bit parallel data processing has improved the transfer speed to 1/4 that of the conventional serial transfer, thereby achieving low power consumption • Applicable common driver : MSM6778 (120 outputs) • Structure: TCP mounting with 35mm wide film (Product name: MSM6669AV-Z-05) Sn-plated Outer lead pitch : 220mm User area : 7.5mm 1/9 ¡ Semiconductor MSM6669 Switching Characteristics Parameter Clock Frequency Clock Pulse Width Rise/Fall Time Data Setup Time Data Hold Time Load Pulse Width Load Setup Time Load → Clock Time "H", "L" Propagation Delay Time EI Setup Time Symbol fCP tW1 tr , tf tDSU tDHD tW2 tLSU tLC tPLH tPHL tESU (VDD = 2.7 to 5.5V, Ta = –20 to +75°C, CL = 15pF) Condition Min.
