Description

The NT7701 is a 160-bit output segment/common driver LSI suitable for driving the large scale dot matrix LCD panels used by PDA's, personal computers and work stations for example. Through the use of SST (Super Slim TCP) technology, it is ideal for substantially decreasing the size of the frame section of the LCD module. It is good as both a segment driver and a common driver, and a low power consuming, high-precision LCD panel display can be assembled using the NT7701. In the segment mode, the data input is selected 4bit parallel input mode or as 8bit parallel input mode by a mode (MD) pin. In common mode, the data input/output pins are bi-directional and the four data shift directions are pin-selectable.
