MOS INTEGRATED CIRCUIT

µPD16448A

SOURCE DRIVER FOR 240-OUTPUT TFT-LCD

(NAVIGATION, AUTOMOBILE LCD-TV)

µPD16448A is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a

variety of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample

analog voltages. Because the two sample and hold circuits alternately execute sampling and holding, a high

definition can be obtained.

In addition, simultaneous sampling and successive sampling are automatically selected according to the pixel

array of the LCD panel. It is ideal for a wide range of applications, including navigation systems and automobile LCD-

TVs.

FEATURES

• Can be driven on 5 V (Dynamic range: 4.3 V, VDD2 = 5.0 V)

• 240-output

• fmax. = 18 MHz (VDD1 = 3.0 V)

• Simultaneous/successive sampling selectable according to pixel array

Simultaneous sampling: vertical stripe

Successive sampling: delta array, mosaic array

• Two sample and hold circuits

• Low output deviation between pins (± 20 mV MAX.)

• Stripe, delta, and mosaic pixel arrays supported by internal multiplexer circuit

• Left and right shift selected by R/L pin

• Single-side mounting possible
