Nexperia USA Inc. 74LVC2G74DC-Q100H

Overview

74LVC2G74DC-Q100 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, 1.65 V to 5.5 V supply range, -40 °C to +125 °C automotive-grade operation, and IOFF partial power-down support. It functions as a synchronous storage element in timing-critical control paths of automotive body electronics and ADAS domain controllers.

For engineers reviewing the 74LVC2G74DC-Q100 datasheet, 74LVC2G74DC-Q100 pinout, 74LVC2G74DC-Q100 application, or 74LVC2G74DC-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, Schmitt-trigger input tolerance for slow-rising signals, ±24 mA output drive at 3.0 V, and guaranteed setup/hold timing across full voltage and temperature range.

Technical Context

This device implements a master-slave D flip-flop architecture with fully asynchronous active-low set and reset controls that override clocked data capture. Its dual-rail input tolerance enables direct interfacing between 3.3 V logic domains and legacy 5 V subsystems without level shifters.

The IOFF circuit disables outputs during power-down to prevent backflow current, while Schmitt-trigger inputs ensure robust operation with rise/fall times up to 20 ns/V at 1.65 V and 10 ns/V at 5.5 V - critical for noisy automotive harness environments.

FAQ

Does 74LVC2G74DC-Q100 support 1.8 V operation?

Yes - it is fully specified from 1.65 V to 5.5 V. At 1.8 V, VIH is 0.65 × VCC (1.17 V min), VIL is 0.35 × VCC (0.63 V max), and propagation delay is 13.4 ns max across -40 °C to +125 °C, making it suitable for low-voltage automotive subsystems.

Can SD and RD be used simultaneously?

No - asserting both SD and RD low results in an invalid output state (Q = Q̅ = H), which violates the functional table. The device requires exclusive activation: SD = L/RD = H sets Q = H, SD = H/RD = L resets Q = L.

What is the maximum clock frequency at 3.3 V?

At VCC = 3.3 V and -40 °C to +125 °C, fmax is 175 MHz. This is derived from tW(min) = 2.7 ns (clock pulse width) and tpd(max) = 5.9 ns, ensuring reliable setup/hold margins in high-speed control loops.

Is the VSSOP8 package RoHS and REACH compliant?

Yes - Nexperia confirms SOT765-1 packaging complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening, with full material declarations available upon request.
