SN74LVC4245ADWG4

Translators, Level Shifters Overview

The SN74LVC4245ADWG4 is an octal bus transceiver and voltage-level shifter manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 3.6 V on the A side and 4.5 V to 5.5 V on the B side, enabling bidirectional data transfer between different logic families. The device features three-state outputs and supports LVTTL input and output levels. 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 a 24-pin TSSOP package.
