Overview
The Nexperia 74AHC273BQ-Q100X is an automotive-grade D-type flip-flop with eight outputs, part of the AHC logic family. It operates within a supply voltage range of 2V to 5.5V and features positive-edge triggering. The component is housed in a DHVQFN-20 package (SOT764) and meets AEC-Q100 qualification standards for automotive applications. It supports surface-mount installation and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Provides eight parallel data outputs triggered by a single clock input
- Complies with AEC-Q100 automotive reliability standards
- Operates efficiently across a wide supply voltage spectrum
Applications
- Automotive electronic control units requiring robust data storage
- Industrial systems utilizing high-speed digital signal processing
- Consumer electronics demanding compact surface-mount solutions
Procurement Notes
Verify the specific suffix 'X' corresponds to the intended reel packaging configuration before ordering. Confirm that the DHVQFN-20 footprint matches the target PCB layout dimensions. Ensure compatibility with the required operating temperature range for the final assembly environment.
Selection Notes
Select this component when designing circuits that require multiple synchronized data latches in a small form factor. It is suitable for designs needing wide voltage tolerance and high noise immunity typical of AHC technology. Consider the thermal performance of the exposed pad during layout planning.
Part Context
This device belongs to the 74AHC series, known for high-speed CMOS operation compatible with standard TTL inputs. The Q100 designation indicates adherence to strict automotive quality requirements. The BQ suffix specifies the DHVQFN package type, distinguishing it from other housing options like TSSOP or SOIC.
Replacement Considerations
Check for equivalent parts such as the 74AHC273PW-Q100J or 74AHC273D-Q100J if different package footprints are acceptable. Verify pinout compatibility when substituting with non-Nexperia equivalents.
