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

Level Shifter for TFT LCD TV Display

MAX1079

Pin Description (continued)

NAME

FUNCTION

Enable Input. All outputs connect to VCOM when EN is low.

Select Input for Two Level/Four Level. Connect CH to VCC for two-level operation and tie CH to

DGND or leave it unconnected for four-level operation. For two-level operation, power VH2 and VL2

and control the outputs with Ax inputs. Bx inputs can be left unconnected or be connected to AGND.

Exposed Pad. Connect the exposed backside pad to AGND and DGND.

Four-Level Combinational Logic

Detailed Description

Connect CH and ST to AGND for four-level combina-

The MAX17079 is a 7-channel level shifter that converts

a 2-bit logic-level input to a five-level high-voltage out-

put. The outputs are connected to the four output rails

(VH1, VH2, VL1, VL2) through 3Ω switches and to the

fifth rail (VCOM) through a 15Ω switch. The output rails

lie between DGND and the upper supply rail (VLS).

tional operation. If EN is LOW or VCC is less than UVLO

or VLS is less than its UVLO, the outputs are in STAND-

BY and the outputs connect to VCOM. After EN is HIGH

or VCC is greater than UVLO and VLS is greater than

its UVLO, the outputs are ready to respond to logic

inputs at Ax, Bx. If EN goes HIGH after a rising or

falling edge of Ax or Bx, the device remains in STAND-

BY state until the next edge comes. All state transitions

can be level triggered. The output is determined by the

following truth table (Table 1).

The MAX17079 has two modes of operation. When

ST = VCC, it operates in sequential mode and when ST

= AGND, it operates in combinational mode. The

MAX17079 can operate in either two-level output or

four-level output configuration. In four-level output

mode, the output can connect to VH1, VH2, VL2, or VL1,

and in two-level output mode, the output can connect to

VH2 or VL2. Connect CH to AGND for four-level opera-

tion and connect CH to VCC for two-level operation.

Table 1. Truth Table Four-Level

Combinational Operation

The output supply rail voltages should satisfy the fol-

lowing condition at all times:

HIGH (Ax)

LOW (Ax)

VLS ≥ VH1 ≥ (VH2, VL2, VCOM) ≥ VL1

OAx = VH1

OBx = VL1

OAx = VL1

OBx = VH1

The MAX17079 has built-in dead time to avoid shoot-

through current. The propagation delay between input

and output is 80ns and the rise time is 30ns.

HIGH (Bx)

LOW (Bx)

OAx = VH2

OBx = VL2

OAx = VL2

OBx = VH2

Figure 1 is the MAX17079 typical operating circuit and

Figure 2 shows the functional diagram.
