Overview
The SN54HC273VTDG2 is an octal D-type flip-flop with a master reset, manufactured by Texas Instruments. It belongs to the SN54HC series of high-speed CMOS logic devices and is supplied in a die configuration for integration into custom substrates or hybrid circuits. The component features eight independent D-type flip-flops, each capable of storing one bit of digital information. Data is transferred from the D inputs to the Q outputs on the positive edge of the clock signal. A dedicated master reset input asynchronously clears all outputs to a low state when activated.
Feature Summary
- Octal architecture providing eight independent D-type flip-flops within a single device structure
- Positive-edge triggered data transfer mechanism synchronized with the clock input
- Master reset functionality that asynchronously clears all output states to low upon activation
- High-speed CMOS technology ensuring compatibility with standard logic families
Applications
- Data storage modules requiring parallel input capture
- Shift register configurations for serial-to-parallel conversion
- State machine implementations in digital control systems
- Memory buffer stages in high-speed data processing circuits
Procurement Notes
Verify the specific die marking and lot code against the manufacturer's latest documentation to ensure authenticity. Confirm that the intended application supports bare die handling requirements, including proper mounting and wire bonding procedures. Check for any recent product change notices regarding material composition or manufacturing site updates. Ensure compliance with relevant environmental regulations such as RoHS standards applicable to the target market.
Selection Notes
Select this component when an octal D-type flip-flop is required in a bare die format for space-constrained or custom hybrid applications. Consider the SN54HC series characteristics for high-speed operation and wide supply voltage ranges. Evaluate the need for asynchronous reset functionality versus synchronous alternatives. Ensure the design environment can accommodate die-level integration rather than packaged IC solutions.
Part Context
This part is part of the SN54HC family, which represents high-speed CMOS logic designed for military-grade temperature ranges and reliability. The 'V' suffix typically denotes a specific version or revision within the HC series, while 'TDG2' indicates the die form factor and packaging type. This family is known for low power consumption and fast switching speeds compared to older logic technologies.
Replacement Considerations
Direct substitutes include other SN54HC273 variants in different packages if die form is not mandatory. For equivalent functionality in packaged form, consider SN74HC273 derivatives, noting the difference in operating temperature ranges between SN54 and SN74 series.
