LC74721

The LC74721 is designed as one kind of common driver LSI for driving large, dot-matrix LCD displays. It features a built-in 64-bit bidirectional shift register and a 4-level LCD driver. This device can also be conected in cascade to increase the number of bits.

Features of the LC74721 are:(1)64 built-in LCD display drive circuits;(2)1/64 to 1/128 display duty cycle;(3)input / outputs for cascade connection;(4)bias supply voltages can be supplied externally;(5)operating supply voltage and ambient temperature;(6)CMOS process;(7)80-pin flat plastic package.

The absolute maximum ratings of the LC74721 can be summarized as:(1)maximum supply voltage: -0.3 to +7.0 V;(2)LCD supply voltage: 0 to 22 V;(3)input voltage: -0.3 to VDD+0.3 V;(4)operating temperature: -20 to +85 ;(5)storage temperature: -40 to +125 .
