Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific suffix designation to confirm pinout and functional configuration, as variants may differ in trigger edge requirements or internal logic mapping. Ensure the procurement source provides original manufacturer documentation from Motorola or NXP to guarantee authenticity. Confirm that the CFLATPACK package condition meets your assembly specifications before finalizing orders.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when designing high-speed ECL-based systems requiring configurable dual-gate functionality. It is appropriate for applications needing precise frequency control in PLL loops where CMOS compatibility is not required. Consider the open-emitter output nature when designing load matching networks for optimal signal integrity at high frequencies.
