Product details
Overview
74LVC2G74GS 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 clock-domain crossing, data synchronization, and control-state latching circuits within mixed-voltage digital systems.
For engineers reviewing the 74LVC2G74GS datasheet, 74LVC2G74GS pinout, 74LVC2G74GS application, or 74LVC2G74GS equivalent, this device is selected for low-voltage logic interfacing, edge-sensitive state capture, and robust noise-immune operation in space-constrained industrial controllers and portable embedded systems requiring dual-supply compatibility and guaranteed power-down isolation.
Technical Context
This flip-flop implements a master-slave D-latch architecture synchronized to the LOW-to-HIGH transition of CP, with Schmitt-trigger inputs enabling tolerance to slow-rising signals and high noise immunity. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences.
It supports bidirectional voltage translation between 3.3 V and 5 V logic domains due to overvoltage-tolerant inputs rated to 5.5 V and rail-to-rail output swing. The device complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full 1.65–5.5 V operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - Enables direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | 1.0 ns to 4.1 ns - Measured CP→Q at VCC = 4.5–5.5 V; ensures sub-5 ns timing in high-speed control paths. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC loads or moderate PCB traces without buffering. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Guarantees safe bus hold and prevents backfeed in hot-swap or multi-rail power sequencing. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive, industrial PLC, and extended-range IoT edge nodes. |
| Input Hysteresis | Schmitt-trigger action - Eliminates metastability from slow or noisy clock/data edges without external RC filtering. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces susceptibility to handling damage and board-level ESD events. |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 8-terminal surface-mount, body dimensions 1.35 mm × 1.0 mm × 0.35 mm, pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CP | Clock input - Edge-sensitive; triggers data capture on LOW-to-HIGH transition only. |
| 2 | VCC | Positive supply - Powers internal logic and output buffers; supports 1.65–5.5 V operation. |
| 3 | D | Data input - Sampled at CP rising edge if setup/hold times met; determines next Q state. |
| 4 | SD | Asynchronous set - Active LOW; forces Q = HIGH independent of CP or D. |
| 5 | Q | True output - Reflects stored D value after CP edge or SD/RD assertion. |
| 6 | RD | Asynchronous reset - Active LOW; forces Q = LOW independent of CP or D. |
| 7 | GND | Ground reference - Return path for all internal currents; must be low-impedance for noise immunity. |
| 8 | Q̅ | Complementary output - Inverted logic of Q; enables differential signaling or feedback paths. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65 V to 5.5 V operation allows use across legacy 5 V, standard 3.3 V, and modern 1.8 V systems without redesign. |
| IOFF Partial Power-Down | Outputs enter high-impedance state when VCC = 0 V, enabling safe insertion/removal in live backplanes or multi-rail subsystems. |
| Schmitt-Trigger Inputs | Input hysteresis rejects noise and accommodates slow rise/fall times up to 20 ns/V, reducing need for external signal conditioning. |
| Overvoltage-Tolerant Inputs | Accepts 5.5 V inputs regardless of VCC level - enables reliable 5 V → 3.3 V translation without external clamping diodes. |
| High-Speed Performance | Maximum clock frequency up to 200 MHz at VCC = 4.5–5.5 V supports real-time sampling in sensor interfaces and protocol engines. |
Applications
| Industrial Motion Control | Automotive Body Controller |
|---|---|

Use Value: Overvoltage-tolerant inputs accept 5 V sensor outputs directly; XSON8 footprint saves <0.7 mm² PCB area in ultra-compact designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74DBVR | Single DFF in SOT-23-6; lacks RD pin (reset-only), no IOFF, max VCC = 5.5 V but no 1.65 V min guarantee. | Not suitable for partial power-down or ultra-low-voltage operation; limited to 3.3 V/5 V only. | Select only if RD functionality is unnecessary and IOFF is not required in system architecture. |
| 74LVC1G79GW,125 | Single DFF in XSON6; no SD/RD pins, edge-triggered only, same 1.65–5.5 V range and IOFF support. | Cannot perform asynchronous state initialization; requires external logic for preset/clear functions. | Choose when minimal footprint is critical and asynchronous control is handled elsewhere in design. |
Compared with SN74LVC1G74DBVR and 74LVC1G79GW,125, the 74LVC2G74GS uniquely delivers full asynchronous set/reset, guaranteed 1.65 V operation, and IOFF in the smallest XSON8 package-making it optimal for space-constrained, multi-rail, and fail-safe embedded control.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LVC2G74GS?
The 74LVC2G74GS is fully specified from 1.65 V to 5.5 V per JEDEC JESD8-7, JESD8-5, and JESD8-B/JESD36 standards. At 1.65 V, it meets all AC/DC specifications including tpd ≤13.4 ns, VIH ≥0.65×VCC, and VOL ≤0.45 V with 4 mA load - enabling reliable use in battery-powered 1.8 V systems.
Does the 74LVC2G74GS support true bidirectional voltage translation?
No - the 74LVC2G74GS supports unidirectional level shifting: inputs tolerate up to 5.5 V regardless of VCC, allowing 5 V signals to safely drive a 3.3 V or 1.8 V system. Outputs swing rail-to-rail (0 V to VCC), so they cannot drive higher-voltage buses without external pull-ups or translators.
How does the IOFF feature behave during power sequencing?
When VCC drops to 0 V, the IOFF circuit automatically places both Q and Q̅ outputs in high-impedance state, limiting I/O leakage to ±2 μA maximum. This prevents back-current flow into powered downstream logic, protecting devices during staggered power-up/down in multi-rail boards.
Can the 74LVC2G74GS replace a 74HC74 in an existing design?
Yes, with qualification: the 74LVC2G74GS offers identical logic function and pinout (in XSON8) but operates down to 1.65 V and features IOFF and Schmitt inputs. However, HC-family users must verify timing margins at lower VCC and confirm that asynchronous SD/RD behavior matches system reset requirements.
