35 MHz clock — timing margin for 5V buses
The 35 MHz maximum clock frequency sets the upper data rate for this register. At 5V with a 50 pF load, the propagation delay is 16 ns max, which defines the setup-to-output window for the downstream logic.
Output drive and quiescent draw
The output stage sources 2.6 mA and sinks 24 mA per pin (high/low), which is typical for ALS logic and sufficient to drive one or two standard TTL loads or a CMOS input with a pull-up. The quiescent supply current is 19 mA — the standing draw on the 5V rail when the clock is running but outputs are static.
Active lifecycle, no obsolescence concern
The SN74ALS374ADW carries an Active product status and is ROHS3 compliant. There is no end-of-life notice or last-time-buy window on this part. For new designs or production replenishment, it is a standard catalog item with no supply-chain urgency. The 74ALS family is mature but still supported; no direct pin-compatible replacement is announced, and none is needed.
