GENERAL DESCRIPTION
The ADG3123 is an 8-channel, noninverting CMOS to high
voltage level translator. Fabricated on an enhanced LC²MOS
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 VDDA, Pin VDDB, and
Pin VSS set the logic levels available at the outputs on the Y side
of the device. Pin VDDA and Pin VDDB set the high output level
for Pin Y1 to Pin Y6 and for Pin Y7 to Pin Y8, respectively. The
VSS 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, VDDB must always be greater than or equal to VDDA
and the voltage between the Pin VDDB and Pin VSS 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.
