Product details

Octal D-type flip-flop for 3.3 V bus interfaces

The Texas Instruments SN74LVTH574DB is an octal D-type flip-flop from the 74LVTH family, designed for 3.3 V bus-oriented systems. It clocks at 150 MHz on a positive edge, with tri-state non-inverted outputs that source 32 mA and sink 64 mA — enough to drive terminated backplane traces or memory data lines without external line drivers. Propagation delay sits at 4.5 ns at 3.3 V with a 50 pF load.

Package and footprint

Housed in a 20-pin SSOP (5.30 mm body width), surface-mount only. The 0.209-inch pitch is standard for SSOP; board layout matches the generic 20-SSOP land pattern used across the 74LVTH and 74LVC families. Supplier device package is 20-SSOP.

Lifecycle and compliance

ROHS3 compliant. The 74LVTH series remains current; no forced migration to a newer family for new designs.

Frequently asked questions

What is the propagation delay of SN74LVTH574DB?

Maximum propagation delay is 4.5 ns at 3.3 V with a 50 pF load. That figure is measured from clock to output (Q) with the output loaded to 50 pF.

Is SN74LVTH574DB RoHS compliant?

Yes, it is ROHS3 compliant.

What is the maximum clock frequency of SN74LVTH574DB?

Maximum clock frequency is 150 MHz. This is the toggle rate for the flip-flop under typical load conditions.
