Overview
The SN74AVC16827DGGR is a 20-bit noninverting buffer/driver produced by Texas Instruments. This device is part of the Widebus™ family and utilizes the Enhanced-Performance Implanted CMOS (EPIC) submicron process. It features Dynamic Output Control (DOC) circuitry, which dynamically changes the output impedance to reduce noise without degrading speed. The buffer is operational over a wide voltage range of 1.2-V to 3.6-V and is specifically designed for 1.65-V to 3.6-V operation, making it versatile for various applications. The device is packaged in a 56-pin Thin Shrink Small Outline (TSSOP) package and is fully specified for operation from -40°C to 85°C.
