Nexperia USA Inc. 74LVC2G74GT,115

Overview

74LVC2G74GT 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 operation, and IOFF partial power-down support. It functions as a synchronous storage element in digital control logic, clock domain interfacing, and level translation between 3.3 V and 5 V systems.

For engineers reviewing the 74LVC2G74GT datasheet, 74LVC2G74GT pinout, 74LVC2G74GT application, or 74LVC2G74GT equivalent, this device is selected for low-voltage mixed-signal timing integrity, Schmitt-trigger noise immunity on all inputs, and guaranteed setup/hold timing across its full voltage and temperature range.

Technical Context

The 74LVC2G74GT implements a master-slave D flip-flop architecture triggered on the LOW-to-HIGH clock transition, with independent active-low asynchronous set and reset that override clocked behavior. Its IOFF circuit disables outputs during power-down to prevent backflow current, and Schmitt-trigger inputs tolerate slow-rising signals up to 10 ns/V at VCC ≥ 2.7 V.

It supports dual-supply interoperability: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), enabling direct interface with both 3.3 V and 5 V TTL/CMOS logic families without external level shifters. Propagation delay ranges from 1.0 ns (VCC = 5.5 V) to 13.4 ns (VCC = 1.65 V), with maximum operating frequency up to 200 MHz at 5 V.

FAQ

Does the 74LVC2G74GT support 1.8 V operation?

Yes. The device is fully specified from 1.65 V to 5.5 V, including reliable operation at 1.8 V. At VCC = 1.8 V, VIH is 0.65×VCC (1.17 V min), VIL is 0.35×VCC (0.63 V max), and tpd is 13.4 ns max - validated across -40 °C to +125 °C per datasheet Table 8 and Table 9.

Can the 74LVC2G74GT be used as a level shifter between 3.3 V and 5 V logic?

Yes. Its overvoltage-tolerant inputs accept 5.5 V signals regardless of VCC, and outputs swing rail-to-rail. When powered at 3.3 V, it reliably accepts 5 V inputs and drives 3.3 V-compatible loads - confirmed by JESD8-7 compliance and VIH/VIL specs in Table 8.

What is the purpose of the IOFF feature, and how does it behave?

IOFF disables outputs when VCC = 0 V, forcing them into high-impedance to prevent backflow current from live I/O lines into a powered-down section. Measured IOFF leakage is ±2 μA max at 5.5 V input and VCC = 0 V - critical for hot-swap and multi-rail power sequencing.

Is the XSON8 package (SOT833-1) compatible with standard reflow profiles?

Yes. The SOT833-1 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard lead-free reflow profiles (peak 260 °C). Its 0.5 mm height and wettable flanks enable automated optical inspection (AOI) and reliable solder joint formation.
