0V Adopts a data bus system 4-bit/8-bit parallel input modes are selectable with a mode (MD) pin Automatic transfer function of an enable signal Automatic counting function which, in the chip selection mode, causes the internal clock to be stopped by automatically counting 240 bits of input data Line latch circuits are reset when /DISPOFF active (Common mode) Shift clock frequency: 4 MHz (MAX.
) Built-in 240-bit bi-directional shift register (divisible into 120 bits x 2) Available in a single mode (240-bit shift register) or in a dual mode (120-bit shift register x 2) Y1->Y240 Single mode Y240->Y1 Single mode Y1->Yl20, Y121->Y240 Dual mode Y240->Y121, Yl20->Y1 Dual mode The above 4 shift directions are pin-selectable Shift register circuits are reset when /DISPOFF active 2.
DESCRIPTION The ST8024T is a 240-output segment/common driver IC suitable for driving large/medium scale dot matrix LCD panels, and is used in personal computers/work stations.
The ST8024T is good both as a segment driver and a common driver, and it can create a low power consuming, high-resolution LCD.
