DESCRIPTION/ORDERING INFORMATION
WWW.100Y.COM.TW WWW.100Y.COM.TW WWW.100Y.COM.TW
This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC8T245
is optimized to operate with VCCA/VCCB set at 1.4 to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The
WWW.100Y.COM.TW WWW.100Y.COM.TW WWW.100Y.COM.TW
port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6 V. The port is designed to
track VCCB. VCCB accepts any supply voltage from 1.2 to 3.6 V. This allows for universal low-voltage
WWW.100Y.COM.TW WWW.100Y.COM.TW WWW.100Y.COM.TW bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

Frequently Asked Questions
What is the required power supply range for this transceiver?
The SN74AVC8T245 is optimized to operate within a 3.6-V power-supply range, but I/Os are 4.6-V tolerant.
How does this device handle different voltage levels?
It supports universal bidirectional translation between voltage nodes like 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V.
Can I use the transceiver for high data rates?
Yes, it achieves a max data rate of 170 Mbps when V ≥ 1.8 V on both input rails.
What is the performance guarantee under various models?
It supports ESD protection exceeding JESD 22 (Human-Body Model) and can handle up to 1000-V Charged-Device Model.
