That 4.2 ns window is the time the output takes to settle after the clock edge — at 150 MHz the clock period is 6.67 ns, so the output is valid for just over 2 ns before the next edge. For a shared address or data bus running at that speed, the setup and hold margins at the receiving end depend on this number, not the clock rate alone. ## 1.65 V to 3.6 V supply — mixed-voltage translation without a level shifter The supply range spans 1.65 V to 3.6 V, so this flip-flop can sit on a 1.8 V core bus or a 3.3 V peripheral bus without a separate level translator. The input thresholds track the supply rail — at 1.8 V the VIH is about 1.2 V, which means a 1.8 V CMOS output drives it cleanly. The 24 mA output drive at both high and low is enough to fan out to four or five standard CMOS loads on a short trace, but at 3.3 V the edge rate into a long backplane trace will reflect — keep the stub length under an inch or add series termination. ## Tri-state outputs and bus arbitration The tri-state, non-inverted outputs let multiple flip-flops share a common data bus. When the output-enable pin is deasserted, the outputs go high-impedance and the bus floats — the next device on the line can drive it without contention. The 3 pF input capacitance per channel is low enough that eight flip-flops on a bus add only 24 pF of load, leaving headroom for the bus driver's capacitive drive limit. ## Industrial temperature grade and surface-mount package Rated for -40°C to +85°C ambient, the part covers factory-floor and outdoor cabinet environments without a commercial-temperature gap. The 48-TVSOP package is the thin version of TSSOP — 4.4 mm body width, 0.4 mm lead pitch. The footprint matches the standard TSSOP-48 land pattern, but the lower package height (1.2 mm max) matters if the board sits behind a cover with tight z-axis clearance. The quiescent current is 40 µA typical, so in a battery-backed system this flip-flop adds negligible draw when the clock is stopped. ## Active lifecycle and sourcing posture Texas Instruments lists the SN74ALVCH16374DGVR as Active with ROHS3 compliance. The part is sourced through authorized and independent distribution channels — quoted to order against the BOM quantity. For a BOM that already carries the 74ALVCH family, this flip-flop is a drop-in without a qualification cycle.","metaTitle":"SN74ALVCH16374DGVR Texas Instruments 74ALVCH D-Type","metaDescription":"SN74ALVCH16374DGVR Texas Instruments 74ALVCH dual 8-bit D-type flip-flop. 150 MHz clock, 1.65-3.6 V supply, 24 mA drive.
