Overview
The CALVC164245MDGGREP, produced by Texas Instruments, is an enhanced product 16-bit noninverting bus transceiver designed for level shifting between different voltage environments. This component features two separate supply rails, allowing for translation from 2.5-V to 3.3-V, 3.3-V to 5-V, and vice versa. It is part of the Texas Instruments Widebus family and is optimized for asynchronous communication between data buses. The device is packaged in a 48-pin TSSOP (DGG) package and operates over an extended temperature range of -55°C to 125°C.
