Nexperia USA Inc. 74LVC1G74GN,115

Overview

74LVC1G74GN,115 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 operating temperature, and XSON8 (SOT1116) 1.2 × 1.0 × 0.35 mm package. It stores D-input data on LOW-to-HIGH clock transitions and supports mixed-voltage interfacing between 3.3 V and 5 V systems in digital control logic.

For engineers reviewing the 74LVC1G74GN,115 datasheet, 74LVC1G74GN,115 pinout, 74LVC1G74GN,115 application, or 74LVC1G74GN,115 equivalent, key selection criteria include propagation delay (as low as 1.0 ns at 5 V), IOFF-enabled partial power-down capability, ±24 mA output drive at 3.0 V, Schmitt-trigger input tolerance for slow edges, and JEDEC-compliant voltage-level translation across 1.65–5.5 V rails.

Technical Context

This device implements a synchronous edge-triggered storage element with fully independent asynchronous set and reset controls active LOW, enabling immediate state override regardless of clock phase. Its dual-output architecture (Q/Q̅) supports direct feedback, toggle, and latch-free state monitoring in sequential logic paths.

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) or 10 ns/V (at 5.5 V). Input overvoltage tolerance to 5.5 V allows safe interfacing with higher-voltage signal sources even when VCC is at 1.65 V.

FAQ

Does the 74LVC1G74GN,115 support 1.8 V operation?

Yes. The device is fully specified from 1.65 V to 5.5 V, including 1.8 V nominal supply. At V_CC = 1.8 V, it delivers guaranteed t_pd ≤13.4 ns, VIH ≥0.65×V_CC, and VOL ≤0.35×V_CC, meeting LVC-family performance targets for low-power portable and battery-operated systems.

Can SD and RD be used simultaneously?

No. When both SD and RD are asserted LOW, the outputs enter a metastable undefined state per the function table. The datasheet explicitly prohibits concurrent activation; design must ensure mutual exclusion via upstream logic or physical interlocking to guarantee predictable Q/Q̅ behavior.

What is the maximum clock frequency at 3.3 V?

At V_CC = 3.0–3.6 V, the maximum guaranteed clock frequency is 175 MHz (t_pd ≤5.9 ns, t_W ≥2.7 ns). With typical performance at 280 MHz, it supports high-speed serial interface control, PWM synchronization, and real-time event capture in FPGA-adjacent logic.

Is the XSON8 package compatible with standard reflow profiles?

Yes. The SOT1116 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and withstands peak reflow temperatures up to 260 °C. Its 0.35 mm profile and copper-leadframe construction ensure reliable solder joint formation under standard lead-free reflow profiles.
