74HC244D Bus Controller IC

产品详情

The 74HC244D from NXP Semiconductors is an 8-bit buffer and line driver integrated circuit belonging to the high-speed CMOS (HC) family. Housed in a compact SOP-20 package, it is designed for surface-mount technology. This octal buffer features non-inverting outputs and is equipped with two active-low output enable pins (1OE and 2OE), each controlling four buffers. Operating from a 5V supply voltage, it is optimized for bus-oriented applications where it can be used to improve signal integrity, drive highly capacitive loads, or isolate bus segments. Its primary function is to provide high-current drive capability while maintaining low power consumption, making it a versatile component for a wide range of digital systems, including data buses, memory address drivers, and general-purpose input/output port isolation. Features High-Speed CMOS Operation: Provides fast signal propagation with low power consumption, typical of the HC family. Octal Buffer/Line Driver: Integrates eight non-inverting buffers in a single package for efficient bus management. Separate Output Enable Control: Features two output enable pins (1OE, 2OE) for independent control of two groups of four buffers. Wide Operating Voltage: Supports a standard 5V supply, compatible with many digital systems. RoHS Compliance: Manufactured with lead-free materials, adhering to environmental regulations.
