GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG3301 is a single-channel, bidirectional logic level
translator. It can be used in multivoltage digital system applications 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.

1. Bidirectional level translation.
2. Fully guaranteed over the 1.15 V to 5.5 V supply range.
3. No direction pin.
4. Compact 6-lead SC70 package.

The voltage applied to VCCA sets the logic levels on the A side of
the device, while VCCY sets the levels on the Y side. For proper
operation, VCCA must always be less than VCCY. The VCCAcompatible logic signals applied to the A pin appear as VCCYcompatible levels on the Y pin. Similarly, VCCY-compatible logic
levels applied to the Y pin appear as VCCA-compatible logic levels
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
high impedance state. The EN pin is referred to the VCCA supply
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.
