ML9473

Semiconductor ML9473 1/3, 1/4, 1/5 Duty 60 Output LCD Driver FEDL9473-01 Issue Date: Aug. 21, 2008 GENERAL DESCRIPTION The ML9473 is a LCD driver for dynamic display providing 3-duty-switchable pins (1/3, 1/4, 1/5 duty). It can directly drive LCDs of up to 300, 240 and 180 segments when 1/5, 1/4 and 1/3 duty are selected respectively. FEATURES Operatin g range Supply voltage : 3.0 to 5.5 V Operating temperature range : 40 to + 105C Segment output : 60 pins 1/5 duty : Up to 300 segments can be displayed. 1/4 duty : Up to 240 segments can be displayed. 1/3 duty : Up to 180 segments can be displayed. Serial transfer clock frequency : 4 MHz Serical interface with CPU :Through three input pins (DATA_IN, LOAD, and CLOCK) Built-in oscillator circuit for COMMON signals One-to-one correspondence between input data and output data When input data is at “H” level : Display goes on. When input data is at “L” level : Display goes off. The entire display can be turned off.
