8 Channel CMOS Logic to High-Voltage Level Translator

Product Details

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 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 VSS 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.

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.

EVAL-24TSSOP Circuit Diagram

Product Details

The EVAL-24TSSOPEBZ evaluation board evaluates 24-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-24TSSOPEBZ to secure a 24-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.

A 24-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K24 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.

Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
