• Memory interface data storage applications

Procurement Notes

This component is subject to discontinuation notification from the manufacturer. Availability is restricted, and the factory may not accept new orders. Verify current stock status and lead times with authorized distributors before design finalization. Consider end-of-life implications for long-term production planning.

Selection Notes

Select this part when an octal latch with high current drive is required within a 3.3 V logic environment. Ensure the application timing requirements align with the 150 MHz maximum clock frequency. Verify that the 20-SSOP package fits the PCB layout constraints and thermal management needs of the target system.

Part Context

The 74LVT534 belongs to the LVT (Low Voltage TTL) series, designed for 3.3 V operation while maintaining compatibility with 5 V tolerant inputs in some configurations. This specific variant integrates eight independent D-type flip-flops into a single integrated circuit, serving as a compact solution for multi-bit data handling in modern embedded designs.

Replacement Considerations

Public confirmed substitute part numbers include 74LVT534D,118 and 74LVT534D,112. These alternatives share the same logical function and pinout but may differ in packaging or manufacturing origin. Verify electrical specifications against original requirements before substitution.
