Outputs are tri-state and non-inverted, so the part can be ganged on a shared data bus without contention — the output-enable control (OE) pulls the bus into high-Z when inactive. ## Supply, temperature, and standby profile The industrial temperature grade spans -40°C to 125°C, covering most factory-floor and outdoor telecom enclosures without derating. Quiescent current is 4 µA typical — negligible for an always-powered bus-hold or address-latch application. The input capacitance is 3 pF per pin, which keeps the clock-line loading low when multiple devices share a common clock tree. ## Through-hole package and board-fit The supplier device package is 20-PDIP; the body width is 0.300 inch, so it fits the narrower DIP footprint, not the 0.600-inch wide-body. For a board rework or repair scenario, the through-hole package is easier to desolder than a fine-pitch SMD. The 74AHCT series is a 5 V CMOS logic family with TTL-compatible input thresholds.","metaTitle":"Texas Instruments SN74AHCT574N D-Type Flip-Flop, 115 MHz","metaDescription":"Active-production 8-bit D-type flip-flop with tri-state outputs. 115 MHz clock, 10.6 ns prop delay at 5V, 50pF.
