Latches Procurement Notes

Verify the exact ordering code 74HCT563DB,112 against current NXP documentation to confirm package type and electrical specifications. Ensure compatibility with system voltage requirements and thermal constraints. Check for any recent product change notices or lifecycle status updates that may affect long-term availability or manufacturing sources. Confirm RoHS compliance if required by specific regulatory standards.

Latches Selection Notes

Select this component when an octal latch with three-state outputs and inverting functionality is required. The HCT series is appropriate for systems interfacing with TTL-level signals. Consider the SSOP package size for space-constrained PCB layouts. Verify that the operating temperature range meets the environmental conditions of the intended application. Compare propagation delays and power consumption against alternative logic families if performance optimization is critical.

Latches Part Context

This part belongs to the extensive 74HCT logic family, widely used in digital electronics for its balance of speed and power consumption. The 74HCT563 specifically addresses the need for parallel data retention with controlled output states. Its design aligns with industry-standard pinouts and electrical characteristics, facilitating drop-in replacements in legacy designs. The manufacturer ensures consistency across the series for predictable system behavior.

Latches Replacement Considerations

Direct substitutes must match the octal D-type latch architecture, three-state inverting outputs, and HCT logic level compatibility. Verify package dimensions and pinout alignment to ensure physical interchangeability. Electrical parameters such as supply voltage range and operating temperature must be equivalent. Consult official cross-reference lists for validated alternatives from NXP or other manufacturers.
