Overview
The Texas Instruments 74LVCH16T245ZQLR is a 16-bit dual-supply noninverting bus transceiver designed for bidirectional voltage level translation. This component is part of the LVC/LCX/Z family and is suitable for applications requiring configurable voltage translation between different voltage nodes. It operates with two separate configurable power-supply rails, allowing each port to accept supply voltages ranging from 1.65 V to 5.5 V. This makes it versatile for use in mixed-voltage-mode data communications.
