Overview
The 74HCT173D,653 is a quad positive-edge triggered D-type flip-flop manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features TTL-compatible input levels. The device includes clock (CP), master reset (MR), and output enable (OE) inputs. It is housed in a 16-SO package with a width of 3.90 mm. The component supports surface mount installation and functions as a single-element logic circuit.
Feature Summary
- Quad positive-edge triggered D-type flip-flop architecture
- TTL-compatible input levels for direct interface
- Three-state outputs controlled by dedicated enable input
Applications
- Data storage registers in digital systems
- Shift register configurations
- Bus-oriented data transmission interfaces
Procurement Notes
Verify the specific suffix '653' against current Nexperia documentation to confirm tape and reel specifications. Confirm that the 16-SO package dimensions match the design footprint requirements. Ensure compatibility with the target operating temperature range of -40°C to +125°C before finalizing procurement orders.
Selection Notes
Select this component when a quad D-type flip-flop with three-state outputs is required. It is suitable for applications needing TTL-level input compatibility within a wide voltage range. Consider the 16-SO package size for PCB layout constraints and verify signal integrity requirements for high-speed switching applications.
Part Context
This part belongs to the 74HCT series of high-c speed CMOS logic devices. It provides a robust solution for sequential logic operations. The device complements other 74HCT family members by offering registered data storage capabilities. Its design aligns with standard JEDEC guidelines for CMOS performance and reliability.
Replacement Considerations
Public confirmed substitute part numbers include CD74HCT173M and CD74HCT173M96 from Texas Instruments. These alternatives offer similar functional characteristics and pinout compatibility. Verify electrical parameters and package dimensions before substitution.
