Overview
The SN74ACT11112D is a dual J-K negative-edge-triggered flip-flop manufactured by Texas Instruments. It features independent clear and preset inputs for direct control of output states. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard CMOS logic levels. It supports low-level output currents of 24 mA and high-level output currents of -24 mA. Propagation delay is typically 10.5 ns at 5 V. The component is housed in a 16-pin SOIC package and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual J-K configuration with negative-edge triggering mechanism
- Independent active-low clear and preset inputs for immediate state control
- High-drive capability with symmetrical output current specifications
Applications
- Parallel data storage circuits
- Shift register implementations
- Frequency division networks
- State machine sequencing elements
Procurement Notes
Verify the specific suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation, noting potential variations in environmental declarations. Ensure the supplier provides valid manufacturer traceability for quality assurance purposes prior to integration into production designs.
Selection Notes
Select this component for applications requiring dual independent flip-flops with dedicated set and reset functionality. The ACT series offers faster switching speeds compared to standard 74LS equivalents while maintaining CMOS power efficiency. Consider the 16-pin surface-mount footprint for space-constrained PCB layouts requiring robust noise immunity and high-speed operation.
Part Context
This part belongs to the Texas Instruments SN74ACT family of high-performance silicon gate CMOS logic devices. The ACT series bridges the performance gap between older TTL technologies and modern CMOS solutions, providing speed comparable to LS-TTL with lower power consumption. The 74ACT11112 specifically addresses design needs for compact sequential logic blocks in digital systems.
Replacement Considerations
Direct pin-compatible substitutes include the SN74ACT11112N (PDIP package) or other manufacturers' equivalent 74ACT11112 variants. Verify that alternative sources maintain identical electrical characteristics, particularly propagation delay and output drive strength, to ensure circuit stability without redesign.
