ST8024S
Overview
The ST8024S 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 ST8024S is good both as a segment driver and a common driver, and it can create a low power consuming, high-resolution LCD.
- n n n
- Number of LCD drive outputs: 240 Supply voltage for LCD drive: +15.0 to +30.0 V Supply voltage for the logic system: +2.5 to +5.5 V Low power consumption Low output impedance (Segment mode)
- Shift clock frequency Ø 20MHz(MAX.):VDD = +5.0 ± 0.5 V Ø 15MHz(MAX.):VDD = +3.0 to + 4.5 V Ø 12MHz(MAX.):VDD = +2.5 to + 3.0 V
- 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)
