MSM5298GS

The MSM5298GS is a kind of dot matrix LCD's common driver LSI fabricated by low power CMOS metal gate technology. The LSI includes 68-bit bidirectional shift register, 68-bit level shifter and 64-bit 4-level driver.The device has 68 output pins to be connected to the LCD. By connecting more than two MSM5298GSs in series, this LSI is applicable to a wide LCD panel. The device can drive a variety of LCD panel because the bias voltage, which determines the LCD driving voltage, can be optionally supplied from the external source.

There are some features as follows: (1)supply voltage: 4.5 to 5.5 V; (2)LCD driving voltage: 8 to 26 V; (3)applicable LCD duty: 1/64 to 1/256, three chips of the MSM5298GS are required to drive 1/200 duty LCD; (4)bias voltage can be supplied externally; (5)80 pin plastic QFP (QFP80-P-1420-K); (6)80 pin VI plastic QFP (QFP80-P-1420-VIK)

What comes next is about the absolute maximum ratings: (1)supply voltage (1), VDD: -0.3 to +6.0 V at Ta=25; (2)supply voltage (2), VDD-VEE: 0 to 27 V when Ta=25 and 0 to 30 V when connecting resistor (RS47) at VEE pin, Ta=25; (3)input voltage, VI: -0.3 to VDD+0.3 V at Ta=25; (4)storage temperature, TSTG: -55 to +150. Then is about the recommended operating conditions: (1)supply voltage (1), VDD: 4.5 to +5.5 V; (2)supply voltage (2), VDD-VEE: 8 to 26 V when Ta=25 and 8 to 28 V when connecting resistor (RS47) at VEE pin, Ta=25; (3)operating temperature, TOP: -20 to +85.

The following is about the DC characteristics (VDD=5 V±10%, Ta=-20 to +85): (1)"H" input voltage, VIH: 0.8VDD V min; (2)"L" input voltage, VIL: 0.2VDD V max; (3)"H" input current, IIH: 1A max when VIH=VDD, VDD=5.5 V; (4)"L" input current, IIL: -1A max when VIH=0 V, VDD=5.5 V; (5)"H" output voltage, VOH: VDD-0.4 V min at IO=-0.4 mA, VDD=4.5 V; (6)"L" output voltage, VOL: 0.4 V max at IO=0.4 mA, VDD=4.5 V; (7)input capacitance, CI: 5 pF typ at f=1 MHz.
