DATA SHEET
MOS INTEGRATED CIRCUIT
µPD16650
120-/128-OUTPUT TFT-LCD GATE DRIVER
The µPD16650 is a TFT-LCD gate driver. Provided with a level shift circuit at the logic input, this chip can output
a high gate scan voltage for a CMOS-level input. The µPD16650 has an output change-over function for switching
from the 120-output mode to the 128-output mode, and vice versa, thereby supporting the VGA, SVGA, and XGA
panels. Its output enable function (OE) enables installing the driver on either side.
FEATURES
• Output with high dielectric strength (on/off range: VDD - VEE1 = 40 VMAX.)
• Built-in shift direction change-over function
• Shiftable negative supply voltage (VEE1) level (shift range: |VEE1 - VEE2| = 10 V)
• Two acceptable CMOS input levels (3.3 and 5 V)
• Output enable function
• MC-selectable output count (MC = high: 120-output mode)
(MC = low : 128-output mode)
• Slim TCP

CAUTIONS FOR USE
1) Power-on sequence
To prevent latch-up disruption, the power must be switched on in the order:
VCC VEE1 VEE2 VDD Logic input
When witching off, reverse the order. This order must be observed also during transition.
2) Insertion of bypass capacitors
The internal logic circuit operates at a high voltage. To make VIH and VIL immune to noise, use capacitors of
0.1 µF or so between supply voltages as shown below.

VCC
0.1µ F
0.1µ F
VSS
VEE2
0.1µ F
3) Negative voltage level shift
If it is necessary to shift the level of a negative supply voltage, shift the VEE1 (driver supply voltage) level. The
shift should be limited to within: VEE2 VEE1 VEE2 + 10 V
Note that shifting the VEE1 level results in the ON-state output resistance and output fall time ratings being
changed.
4) Handling the VEE1 and VEE2 driver negative supply voltage pins
For applications in which a negative supply voltage level is not shifted, connect the VEE1 pin (driver supply voltage)
to the VEE2 pin (logic supply voltage) outside the TCP. Fix all unused input pins to the VEE2 level.
