• 2-bit Unidirectional Voltage-level translator
• Breakout board style EVM for prototype and
evaluation
2 EVM Description
The SN74AVC2T244 is a 2-bit voltage level translator. This translator is a single direction voltage
translator, with OE. When the output-enable (OE) input is high, all outputs are placed in the
high-impedance state. The A port is designed to track VCCA. VCCA accepts any supply voltage from 0.9
V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 0.9 V to 3.6 V.
This allows for low-voltage bidirectional translation between 1-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.3-V
voltage nodes.
The SN74AVC2T244 EVM was created to allow simplified evaluation and prototyping without the need for
full board development. This EVM provides peripheral header style pads for probing and signal connection
to each device pin. Headers are labeled with the corresponding pin name. The pin number assignments
are given in the following table.
