General Description
The NT7704 is a 240-bit output segment/common driver LSI suitable for driving large scale dot matrix LCD panels used by PDAs, personal computers and work stations for example. Through the use of COG technology, it is ideal for substantially decreasing the size of the frame section of the LCD module. The NT7704 is good as both a segment driver and as a common driver, and a low power consuming, high precision LCD panel display can be assembled using the NT7704. In the segment mode, the data input is selected as 4bit parallel input mode or as 8bit parallel input mode by a mode (MD) pin. In the common mode, the data input/output pins are bi-directional and the four data shift directions are pin-selectable.

FEATUREs
(Segment mode)
■ Shift Clock frequency:
   20 MHz (Max.) (VDD = 5 V ± 10%)
   12 MHz (Max.) (VDD = 2.5V - 4.5V)
■ Adopts a data bus system
■ 4-bit/8-bit parallel input modes are selectable with a mode (MD) pin
■ Automatic transfer function with an enable signal
■ Automatic counting function when in "chip select" mode,
   which causes the internal clock to be stopped by
   automatically counting 240 bits of input data
   (Common mode)
■ Shift clock frequency : 4.0 MHz (Max.)
■ Built-in 240-bits bidirectional shift register (divisible into 120-bits x 2)
■ Available in a single mode (240-bits shift register) or in a
   dual mode(120-bits shift register x 2)
   1. Y1 → Y240 Single mode
   2. Y240 → Y1 Single mode
   3. Y1 → Y120, Y121 → Y240 Dual mode
   4. Y240 → Y121, Y120 → Y1 Dual mode
   The above 4 shift directions are pin-selectable
   (Both for segment mode and common mode)
