GENERAL DESCRIPTION

The ADG3301 is a single-channel, bidirectional logic level

translator. It can be used in multivoltage digital system applica-

tions such as data transfer between a low voltage DSP/controller

and a higher voltage device. The internal architecture allows the

device to perform bidirectional logic level translation without an

additional signal to set the direction in which the translation

takes place.

on the A pin. The enable pin (EN) provides three-state operation

on both the A pin and the Y pin. When the device enable pin is

pulled low, the terminals on both sides of the device are in the

voltage and driven high for normal operation.

The ADG3301 is available in a compact 6-lead SC70 package

and is guaranteed to operate over the 1.15 V to 5.5 V supply

voltage range and extended −40°C to +85°C temperature range.
