• Near-Zero propagation delay
• VCC = 1.65V to 3.6V
• Ultra-Low Quiescent Power: 0.1 A typical
• Ideally suited for low power applications
•
3.3V to 2.2V level shifting
•
2.5V to 1.6V level shifting
• Industrial operating temperature: -40
°C to +85°C
• Available in 8pin TSSOP package
Potato Semiconductor’s PO3VT3305A is
designed for world top performance using
submicron CMOS technology to achieve GHz
high bandwidth.
The PO3VT3305A is a High-Bandwidth, Hot-
Insertion, 2-Bit, 2-Port, Signal Voltage Translator
Bus Switch.PO3VT3305A can do voltage level
shifting from 3.3V to 2.2V or 2.5V to 1.6V.
The switch introduces no additional ground
bounce noise or propagation delay.

Notes:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, 25
