Product Overview
The SN74LVC8T245 is an 8-bit non-inverting dual-supply bus transceiver from Texas Instruments. It is intended for bidirectional voltage translation using configurable VCCA and VCCB supply rails, with each supply specified for 1.65 V to 5.5 V operation under recommended operating conditions.
The device supports active input/output operation from 0 to VCCO and 3-state input/output operation from 0 to 5.5 V. Control inputs are referenced to VCCA, and the DIR input current is specified at +/-1 uA typical and +/-2 uA maximum over 1.65 V to 5.5 V VCCA and VCCB conditions.
Output drive capability depends on VCCO, with high-level output current ratings from -4 mA to -32 mA and low-level output current ratings from 4 mA to 32 mA across the listed voltage ranges. Package options include DB SSOP-24, DBQ SSOP-24, PW TSSOP-24, DGV TVSOP-24, and RHL VQFN-24 for board-level assembly choices.
