Clock frequency reaches 140 MHz, which sets the maximum toggle rate the device can sustain into a 50 pF load — above that, the internal propagation delay of 11.4 ns at 5 V starts to limit setup-and-hold margin. ## Supply rails, drive, and temperature range Temperature range spans -40°C to 125°C ambient — the full industrial-plus-automotive underhood band. A design that sees 105°C in an engine-bay ECU or 85°C in a motor-drive cabinet still has margin before the 125°C ceiling. ## 14-TSSOP package and PCB integration Housed in a 14-lead TSSOP with 0.173-inch body width and 4.40 mm nominal width — the thin-shrink small-outline package that saves board real estate compared to a SOIC-14. Supplier device package is 14-TSSOP; the 0.65 mm pitch fans out easily on a two-layer board with 6/6 mil trace/space. No exposed pad, so thermal relief is through the leadframe only — keep the ground pins tied to a solid plane for heat sinking. ## Active production and compliance Texas Instruments lists the SN74AHCT74PW as Active with ROHS3 compliance.","metaTitle":"SN74AHCT74PW Texas Instruments D-Type Flip-Flop, 140 MHz","metaDescription":"SN74AHCT74PW dual D-type flip-flop with set/reset, 140 MHz clock, 8 mA output, -40 to 125°C.

The SN74AHCT74PW runs at 140 MHz with 11.4 ns delay at 5 V and is not pin-compatible — the 74HCS part comes in a different package (QFN vs TSSOP) and targets automotive (AEC-Q100) applications."},{"question":"What compliance documentation does Texas Instruments provide for SN74AHCT74PW?","answer":"Texas Instruments provides ROHS3 compliance for the SN74AHCT74PW.
