Texas Instruments 20-SOIC SN74HC244QDWREP

The part number "SN74HC244QDWREP" likely refers to a variant within the Texas Instruments' SN74HC244 family of octal buffer/line driver ICs. This CMOS-based component features 8 single-ended channels, designed for high-speed operation with low power consumption and high noise immunity. It typically has separate output enables (OE) for two groups of four outputs, allowing them to be tri-stated when OE is high, presenting a high impedance state. The "QDWREP" suffix might denote specific packaging, temperature range, or qualification such as automotive grade or enhanced reliability. However, this exact part number doesn't appear in standard TI documentation; please verify its specifications with the manufacturer's datasheet.
