It captures data on the positive edge of the clock and presents the inverted state on tri-state outputs. The 125 MHz clock rate and 9 ns propagation delay (at 5V, 50 pF) suit it for high-speed bus interfaces, address latching, and register files in 5V systems. The 20-SOIC wide-body package (7.50 mm width) is a common footprint for board-level logic integration. ## Lifecycle and sourcing It is RoHS non-compliant (per the listing), so verify your assembly house's exemption policy if you need lead-free solder.","metaTitle":"SN74AS534DWR D-Type Flip-Flop, 125 MHz, Tri-State Inverted","metaDescription":"TI SN74AS534DWR is an 8-bit D-type flip-flop with tri-state inverted outputs, 125 MHz clock, 9ns propagation delay at 5V.
