Product details

200 MHz 9-bit D-type — 5V bus timing anchor

The SN74ABT823DW is a 9-bit D-type flip-flop with master reset and tri-state non-inverted outputs, clocked at 200 MHz on a positive edge. With a max propagation delay of 6.1 ns at 5 V into 50 pF, this part holds timing margin in clock trees where the downstream setup window is tight. The 32 mA source / 64 mA sink output drive lets it fan out to multiple loads without a separate line driver.

Industrial temp, 24-SOIC — panel and board-fit

The 24-SOIC package (0.295-inch body width) is a common surface-mount footprint; it is not the narrower 0.150-inch SOIC or the finer-pitch TSSOP, so a board laid out for those will need a pad revision. Input capacitance is 4 pF per pin, and quiescent current sits at 250 µA — the load on the upstream driver and the power rail is modest even with all nine bits toggling.

Frequently asked questions

Will SN74ABT823DW drop into a board laid out for SN74LVC574APWT?

No — the SN74LVC574APWT is an 8-bit register in a different package (TSSOP or similar) running on a 1.65 V supply. The 74ABT823DW is a 9-bit part in a 24-SOIC (0.295-inch) body with a 5 V supply. The pinout, footprint, and voltage domain are incompatible without a board spin.
