DESCRIPTION

The ST8016T is a 160-output segment/common driver IC suitable for driving large/medium scale dot matrix LCD panels, and is used in personal computers/work stations. The ST8016T is good both as a segment driver and a common driver, and it can create a low power consuming, high-resolution LCD.

FEATURES

■ Number of LCD drive outputs: 160

■ 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

- 20 MHz (MAX.): VDD = +5.0 ± 0.5 V

- 15 MHz (MAX.): VDD = +3.0 to + 4.5 V

- 12 MHz (MAX.): VDD = +2.5 to + 3.0 V

■ 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 160 bits of input data

■ Line latch circuits are reset when /DISPOFF active (Common mode)

■ Shift clock frequency: 4 MHz (MAX.)

■ Built-in 160-bit bi-directional shift register (divisible into 80 bits x 2)

■ Available in a single mode (160-bit shift register) or in a dual mode (80-bit shift register x 2)

- Y1->Y160 Single mode

- Y160->Y1 Single mode

- Y1->Y80, Y81->Y160 Dual mode

- Y160->Y81, Y80->Y1 Dual mode

The above 4 shift directions are pin-selectable

■ Shift register circuits are reset when /DISPOFF active
