GENERAL DESCRIPTION

The MSM5238 is a dot matrix LCD common driver LSI which is fabricated using low power CMOS metal gate technology. The scanning signal in one matrix display frame can be divided into up to 1/32 duty. This LSI consists of 32-bit shift register, 32-bit level shifter and 32-bit 4-level driver.

This LSI can drive a variety of LCD panels because the bias voltage, which determines the LCD driving voltage, can be optionally supplied from an external source.

FEATURES

• Supply voltage : 3 to 7V

• LCD driving voltage : 3 to 16V

• Applicable LCD duty : 1/32 to 1/64 (1/64 duty is available when MSM5238s are cascade-connected)

• Bias voltage can be supplied externally.

• Applicable segment driver: MSM5839B/C (40 outputs)
