The HD74AC244FPEL is an octal buffer/line driver with three-state outputs manufactured by Renesas Electronics America. It belongs to the Advanced CMOS (AC) logic family, providing high-speed operation and low power consumption. The three-state outputs allow the device to be effectively disconnected from the bus, enabling multiple devices to share the same bus.

Applications

• Memory address drivers
• Clock drivers
• Bus interface
• Data transmission
• Logic level conversion

Features

• Octal buffer/line driver

• Low power consumption
• Wide operating voltage range (2V to 6V)
• High output drive capability

Benefits

• Isolates and buffers signals
• Enables multiple devices to share the same bus
• High speed allows for use in demanding applications
• Low power consumption reduces system power requirements
• Wide operating voltage range simplifies system design
• High output drive capability enables driving heavily loaded lines

Technical Specifications

The HD74AC244FPEL consists of eight independent buffer/line drivers. Each driver has a single input and a three-state output. The outputs are enabled or disabled by two enable inputs (OE1 and OE2). When OE1 and OE2 are low, the outputs are enabled, and the output signals follow the input signals. When either OE1 or OE2 is high, the outputs are in the high-impedance state. The device operates over a wide temperature range, typically -40°C to +85°C. The HD74AC244FPEL is characterized by its high speed, low power consumption and high output drive. The specific operating voltage range, input/output voltage levels, and timing characteristics are detailed in the Renesas datasheet. The package is typically a SOP (Small Outline Package).
