产品概览
SN74LVC8T245DGVR from TI is an 8-bit dual-supply voltage-level translator with 3-state outputs. Separate VCCA and VCCB (1.65-5.5V) for bidirectional level shifting. TVSOP-24.
工作原理
Dual-supply design: A-port referenced to VCCA, B-port to VCCB. Direction pin (DIR) controls A-to-B or B-to-A. OE enables 3-state outputs. Allows voltage translation between any two levels from 1.65V to 5.5V.
