What are the key features of 74ACT11244DWG4?
- Octal 3-state outputs with 24 mA sink/source drive for direct bus loading across backplane and memory interfaces
- ACT-logic family with 5 V TTL-compatible inputs enabling mixed 3.3 V / 5 V system interfacing without level translators
- 24-pin wide-body SOIC (SOIC-24, 0.4-inch) package minimizing board area while maintaining industry-standard footprint
What is 74ACT11244DWG4 used for?
The 74ACT11244DWG4 is used in memory bus buffering, microprocessor address/data line driving, and backplane interface circuits where 3-state control prevents bus contention during bus sharing. Its 24 mA output current handles capacitive loads up to 50 pF typical on 5 V digital backplanes. Industrial control systems, legacy embedded boards, and test equipment rely on this device to extend address buses and isolate subsystems with minimal propagation delay.

Frequently Asked Questions
How much output drive current does the 74ACT11244DWG4 provide and which bus loads can it handle?
The 74ACT11244DWG4 delivers 24 mA sink current per output at VOL max 0.55 V, sufficient to drive standard TTL loads and backplane traces with up to 50 pF capacitance per line. All 8 outputs switching simultaneously still meet timing specs at 5 V supply, making it reliable for 8-bit address or data bus buffering.
For a 5 V microprocessor board that must isolate its address bus, how does the 3-state feature of 74ACT11244DWG4 prevent bus contention?
The active-low OE pins tri-state all 8 outputs simultaneously, disconnecting the buffer from the bus within 7 ns typical. This prevents contention when multiple bus masters share 8 address lines, a common requirement in DMA controller or multi-master memory systems running at 40 MHz or faster.
What propagation delay should designers expect from 74ACT11244DWG4 in a 5 V backplane design?
Propagation delay tpd is typically 5 ns at 5 V VCC, which is faster than the 74HC244 family at approximately 7 ns, allowing the 74ACT11244DWG4 to fit in bus cycles as short as 20 ns without introducing setup-time violations on downstream latches or SRAM devices.
