- 3-state output control on all 8 channels enables bidirectional bus sharing with complete output isolation when disabled
- 24 mA sink current per output provides strong drive capability for backplane bus lines and heavy capacitive loads
- AC CMOS family delivers fast propagation delays with low power consumption compared to older ALS and F-series logic families
Applications
The 74AC11244DWG4 is commonly used in data bus buffering, address line driving, and memory interface circuits in microprocessor-based systems and FPGA designs. It is well-suited for PCI, ISA, and custom parallel bus applications where multiple output channels need to be tristated individually to prevent bus contention, as well as for signal level amplification in backplane and card-edge interface designs.

Frequently Asked Questions
What does the 3-state output feature mean for the 74AC11244DWG4?
The 3-state outputs on the 74AC11244DWG4 allow each output to be driven high, driven low, or placed into a high-impedance state, enabling multiple devices to share the same bus without signal contention when they are not actively driving the bus lines.
What is the output sink current capability of the 74AC11244DWG4?
The 74AC11244DWG4 provides a maximum output low sink current (IOL) of 24 mA per channel, making it capable of driving heavily loaded bus lines, LED indicators, and other medium-current loads directly from the output pins.
What logic family does the 74AC11244DWG4 belong to?
The 74AC11244DWG4 belongs to the AC (Advanced CMOS) logic family, which offers fast switching speeds with significantly lower power consumption compared to TTL-compatible families, making it suitable for high-speed digital systems with tight power budgets.
What package is the 74AC11244DWG4 available in?
The 74AC11244DWG4 is available in a 24-pin SOIC (Small Outline Integrated Circuit) package, providing a medium-density footprint that is compatible with standard surface-mount assembly processes and widely used PCB land patterns.
What are typical applications for the 74AC11244DWG4?
Typical applications include data bus buffering between processor and memory, address bus driving in microcontroller systems, I/O port expansion, and signal level translation in embedded systems where the 8-channel 3-state outputs allow efficient use of shared parallel buses.
