Overview
The 74HC273PW/S911118 is an octal D-type flip-flop with a positive-edge trigger and asynchronous reset, manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and features high noise immunity. The device provides eight outputs and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. It is specified for operation from -40 °C to +85 °C and complies with JEDEC standards.
Feature Summary
- Octal D-type flip-flop architecture with positive-edge triggering
- Asynchronous reset functionality for immediate output clearing
- Input clamp diodes enable direct interface with voltages above VCC
Applications
- Parallel data storage in digital systems
- Shift register construction
- Timing delay circuits
Procurement Notes
Verify the specific suffix S911118 against official Nexperia documentation to confirm package orientation and tape-and-reel specifications. Ensure compatibility with standard TSSOP-20 footprint requirements during PCB layout. Confirm that the ordering code matches the intended production volume and delivery schedule constraints.
Selection Notes
Select this component when an octal storage element is required with wide voltage tolerance. The HC series offers robust performance across 2.0 V to 6.0 V ranges. Consider the asynchronous reset feature if immediate clearing of stored data is necessary without waiting for clock cycles. Verify input drive capabilities match the source logic levels.
Part Context
This part belongs to the 74HC family of high-speed CMOS logic devices. It is designed for applications requiring fast switching speeds and low power consumption. The HC series is widely used in general-purpose digital electronics due to its compatibility with TTL logic levels and broad operating voltage range.
Replacement Considerations
Check for equivalent parts such as 74HC273D or 74HC273N from other manufacturers. Ensure pinout compatibility and electrical characteristics match the original design requirements before substitution.
