SN74LVC4245ADBR

Translators, Level Shifters Overview

The SN74LVC4245ADBR is an octal bus transceiver and voltage-level shifter manufactured by Texas Instruments. It operates with a dual power supply configuration: VCCA ranges from 2.7 V to 3.6 V, while VCCB ranges from 4.5 V to 5.5 V. The device features eight non-inverting channels with three-state outputs. Key electrical parameters include a propagation delay of 6.7 ns, low-level output current of 24 mA, and high-level output current of -24 mA. It functions within a temperature range of -40°C to +85°C and is housed in an SSOP-24 package.

Translators, Level Shifters Feature Summary

• Provides bidirectional data transmission between buses operating at different voltage levels
• Enables seamless interface between 3.3-V and 5-V systems without board re-layout
• Offers controlled directionality via DIR input and isolation capability through OE input

Translators, Level Shifters Applications

• Asynchronous communication between data buses
• Voltage translation between 3.3-V and 5-V logic domains
