Product details

What this part is and where it fits

The Texas Instruments SN74AS534DWR is an 8-bit D-type flip-flop from the Advanced Schottky (AS) logic family. 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.

Frequently asked questions

What is the difference between SN74AS534 and SN74AS574?

The SN74AS534 provides inverted outputs, while the SN74AS574 provides non-inverted outputs. Both are 8-bit D-type flip-flops with tri-state outputs and share the same pinout and package options.

What is the closest functional second-source for SN74AS534DWR?

A close functional peer is the 74F374SCX-NS from the Fairchild 74F series. It offers similar speed (140 MHz clock, 8.5 ns propagation delay at 5V, 50 pF) but with non-inverted outputs. The 74F374 is also a positive-edge triggered 8-bit D-type in a surface-mount package, though pin compatibility should be verified against the specific footprint.
