Overview
The IDT 74LVC273AE4Q is an octal D-type flip-flop with clear, manufactured by Integrated Device Technology. It operates within a voltage range of 2.7V to 3.6V and features three-state outputs. The device supports mixed-mode operation on all ports, allowing inputs to accept voltages from both 5V and 3.3V systems. It includes overvoltage protection on inputs and outputs, ensuring robust performance in diverse logic environments.
Feature Summary
- Octal D-type flip-flop architecture with direct clear functionality
- Three-state outputs for bus-driven applications
- Mixed-mode I/O supporting 5V and 3.3V signal levels
- Overvoltage protection on all input and output pins
Applications
- Parallel-to-serial data conversion circuits
- I/O buffering and port expansion in embedded systems
- Timing synchronization in digital control logic
Procurement Notes
Verify the specific suffix 'E4Q' against official IDT documentation to confirm package type and temperature grade. Ensure compatibility with 3.3V logic families. Confirm RoHS compliance status as required by project specifications before finalizing procurement.
Selection Notes
Select this component when an octal storage element with mixed-voltage tolerance is required. It is suitable for designs needing isolation between 5V and 3.3V domains. Consider the three-state output capability if bus sharing is necessary. Verify pinout compatibility with existing PCB layouts.
Part Context
This part belongs to the 74LVC family of low-voltage CMOS logic devices. It provides high-speed performance with reduced power consumption compared to older TTL standards. The device is designed for general-purpose digital logic applications requiring reliable data latching and transfer capabilities.
Replacement Considerations
Check for cross-reference parts such as SN74LVC273A or MC74LVC273ADTR2G. Ensure functional equivalence regarding voltage ranges and pin configurations. Verify that substitute components meet the same ESD and latch-up protection standards.
