Flip Flops Procurement Notes

Verify the specific suffix DL indicates the 56-pin SSOP package configuration. Confirm the operating temperature range matches system requirements, as industrial grades may differ. Ensure supply voltage compatibility with the 1.65 V to 3.6 V specification. Check for any specific ordering prefixes or suffixes that might affect pinout or electrical characteristics compared to standard variants.

Flip Flops Selection Notes

Select this component when 20-bit parallel data storage with 3-state output control is required at speeds up to 150 MHz. The low input capacitance makes it suitable for high-speed bus applications. Consider the SSOP package constraints for PCB layout. Verify that the 3.3-V nominal supply aligns with the system's logic levels and power budget.

Flip Flops Part Context

This part belongs to the SN74ALVCH series of 3.3-V advanced low-voltage CMOS logic devices. It is designed for high-speed memory and microprocessor-based systems. The 20-bit width allows for efficient handling of wide data buses. The 3-state outputs facilitate direct connection to shared data lines without external buffers.

Flip Flops Replacement Considerations

Check for SN74ALVC16721 variants if tri-state outputs are not required. Verify pin compatibility with SN74ALVCH16721DGR or other package options like DGQ if space constraints differ. Ensure substitute parts maintain the 150 MHz speed grade and 3.3-V operation.
