4-Level or 2-Level Logic to High-Voltage

Level Shifter for TFT LCD TV Display

MAX1079

General Description

Features

♦ 7-Channel Logic-Level Input to High-Voltage

The MAX17079 is a 7-channel logic-level input to high-

voltage output level shifter. Each channel has two

inputs plus a shared enable input. Each channel has

two outputs, which can be set to five output levels. Two

outputs are complementary to each other. The five out-

put levels are set by five supply rails that are common

to all 14 outputs.

Output Level Shifter

♦ Complementary Outputs in Each Channel

♦ VLS Input Range from 10V to 18V

♦ VCC Input Range from 2.3V to 3.6V

♦ 2-Level or 4-Level Operation

♦ Sequential or Combinational Logic

♦ 3Ω Output Switches

The five supply rails include a typical TFT VCOM rail.

Two upper rails are always greater than VCOM, with

VH1 always greater than VH2. The two lower rails are

always less than VCOM, with VL1 always less than VL2.

Other supply rails are VLS (the typical TFT AVDD sup-

ply) and VCC (the logic supply). The MAX17079 can

also be configured as a two-level voltage shifter.

♦ 5-Level Output

♦ Short Propagation Delay (80ns typ)

♦ Fast Rise Time (30ns typ)

♦ Built-In Dead Time to Prevent Shoot-Through

♦ Thermal Shutdown

When EN is low, all 14 outputs connect to VCOM, and

when EN is high, the outputs are determined by their

inputs. The logic inputs are driven by the timing con-

troller. The output switches are typically 3Ω with low

propagation delays and fast rise times. The MAX17079

has a minimum dead time to prevent shoot-through cur-

rents between supplies. The MAX17079 has thermal

shutdown to protect against overheating, VCC under-

voltage lockout (UVLO), and VLS UVLO.

♦ VLS and VCC Undervoltage Lockout
