SN74LVC4245ADB

Translators, Level Shifters Overview

The SN74LVC4245ADB is an octal bus transceiver and voltage-level shifter manufactured by Texas Instruments. It features dual power supplies, with VCCA supporting 2.7V to 3.6V and VCCB supporting 4.5V to 5.5V. The device provides eight non-inverting channels with three-state outputs and a propagation delay of 6.7 ns. It operates within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.

Translators, Level Shifters Feature Summary

• Supports asynchronous communication between data buses via directional control inputs
• Enables voltage translation between 3.3V and 5V domains without board re-layout
• Provides high-impedance isolation when output enable is deactivated
