GENERAL DESCRIPTION

The

ADG3123

is an 8-channel, noninverting CMOS to high

voltage level translator. Fabricated on an enhanced LC

MOS

process, the device is capable of operating at high supply

voltages while maintaining ultralow power consumption.

The internal architecture of the device ensures compatibility with

logic circuits running from supply voltages within the 2.3 V to

5.5 V range. The voltages applied to Pin V

DDA

, Pin V

DDB,

and

Pin V

set the logic levels available at the outputs on the Y side

of the device. Pin V

DDA

and Pin V

DDB

set the high output level

for Pin Y1 to Pin Y6 and for Pin Y7 to Pin Y8, respectively. The

pin sets the low output level for all channels. The

ADG3123

can provide output voltages levels down to −24.2 V for a low input

level and up to +35 V for a high input logic level. For proper

operation, V

DDB

must always be greater than or equal to V

DDA

and the voltage between the Pin V

DDB

and Pin V

should not

exceed 35 V.

The low output impedance of the channels guarantees fast rise

and fall times even for significant capacitive loads. This feature,

combined with low propagation delay and low power consumption,

makes the

ADG3123

an ideal driver for TFT-LCD panel

applications.

The

ADG3123

is guaranteed to operate over the −40°C to +85°C

temperature range and is available in a compact, 20-lead TSSOP,

Pb-free package.

PRODUCT HIGHLIGHTS

Compatible with a wide range of CMOS logic levels.

High output voltage levels.

Fast rise and fall times coupled with low propagation delay.

Ultralow power consumption.

Compact, 20-lead TSSOP, RoHS-compliant package.
