Overview
The IDT54FCT273CT is an octal D flip-flop constructed using advanced dual metal CMOS technology. It features eight edge-triggered D-type flip-flops with individual data inputs and outputs, alongside common buffered Clock and Master Reset inputs. The device provides true TTL input and output compatibility, characterized by a typical high-level output voltage of 3.3V and a low-level output voltage of 0.3V. It supports high drive capabilities with a maximum output current of -15mA for high state and 48mA for low state. Input and output leakage currents are maintained at a maximum of 1µA, ensuring low power consumption consistent with CMOS standards.
Feature Summary
- Octal configuration with eight independent edge-triggered D-type flip-flops
- Common buffered Clock and Master Reset inputs for simultaneous control
- True TTL input and output compatibility with specified voltage levels
- High drive output capability supporting significant load currents
Applications
- General-purpose digital storage registers
- Memory address buffering systems
- Data acquisition and processing circuits
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'TEB' against official Integrated Device Technology documentation to confirm package type and temperature range. Ensure the component matches the radiation-tolerant or standard commercial grade requirements. Cross-reference the manufacturer part number with the distributor's listing to confirm authenticity and avoid counterfeit components. Check for any specific handling instructions related to the bulk packaging method mentioned in available references.
Selection Notes
Select this component when an octal register with common clock and reset signals is required. Consider the high drive outputs if interfacing with multiple loads. Verify that the TTL compatibility meets the system voltage requirements. Evaluate the speed grade options if timing constraints are critical. Ensure the package style fits the PCB layout constraints.
Part Context
This component belongs to the IDT FCT (Fast CMOS) family, which bridges the performance gap between standard CMOS and TTL logic. The FCT series is designed for high-speed applications while maintaining low power consumption. The 54/74FCT273 variant specifically offers octal storage functionality, making it suitable for complex digital systems requiring parallel data latching.
Replacement Considerations
Compatible substitutes include other octal D flip-flops from the same FCT family, such as the IDT74FCT273T or IDT54FCT273AT. Ensure the replacement maintains the same pinout and electrical characteristics. Verify that the alternative part supports the required speed grade and package type for the specific application.
