Overview
The CD74ACT175EE4 is a quad D-type flip-flop with reset from the Texas Instruments ACT logic series. It features TTL-compatible inputs and CMOS outputs in a 16-pin PDIP package. The device operates within a supply voltage range of 1.5 V to 5.5 V. Key electrical parameters include a propagation delay of 11.5 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It supports through-hole mounting and functions across an industrial temperature range of -55 °C to +125 °C.
Feature Summary
- Integrates four independent D-type flip-flops with master reset functionality within a single integrated circuit.
- Utilizes silicon gate CMOS technology to achieve LSTTL-like operating speeds while maintaining standard CMOS low power consumption characteristics.
- Provides TTL-compatible input levels for direct interfacing with TTL-driven systems without requiring additional level shifting components.
Applications
- High-speed data storage registers
- Shift register implementations
- Parallel-to-serial conversion circuits
Procurement Notes
Verify the specific EE4 suffix against the manufacturer's official documentation to confirm the exact packaging configuration and environmental compliance status. Ensure that the procurement channel provides valid traceability for the component lot. Cross-reference the ordering information with the latest datasheet revisions to avoid discrepancies in pinout or electrical specifications during integration.
Selection Notes
Select this component when designing systems requiring fast switching speeds combined with low power dissipation. The wide supply voltage range allows flexibility in power domain design. Verify that the required input drive capabilities match the TTL compatibility profile. Consider the PDIP package constraints for thermal management and PCB layout space compared to surface-mount alternatives.
Part Context
This part belongs to the CD74ACT175 family of quad D-type flip-flops. It shares functional similarities with other members like the CD74ACT174 but differs in the number of internal flip-flop stages. The ACT series represents a transition between older LS logic and modern HC/HCT technologies, offering superior speed performance suitable for demanding digital logic applications.
Replacement Considerations
Direct substitutes include the CD74ACT175E and CD74ACT175N. Verify pinout compatibility and electrical parameter equivalence before substitution. Alternative packages such as SOIC may require adapter considerations if footprint changes are acceptable.
