Single-bit D-type with tri-state — what it does on your board
It clocks at 175 MHz, operates from 1.65V to 5.5V, and sinks or sources 32 mA per pin. The SC-70-6 package fits tight layouts where a full 8-bit register is overkill — think glue logic for a single status latch, a bus-hold buffer, or a one-bit pipeline stage in a mixed-voltage design.
Supply range and temperature — where it lives
Quiescent current sits at 10 µA, so it won't eat into a battery budget in a sensor node that only wakes to latch a reading.
175 MHz and 4 ns propagation delay — timing closure
A 175 MHz clock frequency with 4 ns propagation delay at 5V, 50 pF means this part keeps up with fast SPI or parallel bus handshakes without adding a clock cycle of latency. The 3 pF input capacitance is light enough that a series of these on a shared clock line won't load the oscillator into failure.
No end-of-life notice to track, no last-time-buy window to hit.
