Product details
Overview
74LVC1G79GM,115 from Nexperia is a single positive-edge-triggered D-type flip-flop in XSON6 (SOT886) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF circuitry enabling partial power-down mode. It functions as a synchronous data latch in clock-domain crossing, level translation, and metastability mitigation circuits in industrial control and sensor interface designs.
For engineers reviewing the 74LVC1G79GM,115 datasheet, 74LVC1G79GM,115 pinout, 74LVC1G79GM,115 application, or 74LVC1G79GM,115 equivalent, this device is selected for low-voltage mixed-signal interfacing where rail-to-rail input tolerance, sub-10 ns propagation delay at 3.3 V, and guaranteed operation up to +125 °C are required - especially in space-constrained PCBs using its 1.0 × 1.45 mm XSON6 footprint.
Technical Context
This flip-flop implements a classic master-slave D-latch architecture synchronized to the rising edge of CP. Its Schmitt-trigger inputs accept slow-rising signals (≤10 ns/V transition rate supported), while IOFF disables outputs during VCC = 0 V to prevent backflow current in hot-swap or power-gated systems.
It supports bidirectional voltage translation between 3.3 V and 5 V logic domains without external biasing, thanks to overvoltage-tolerant inputs rated to 5.5 V independent of VCC. The device meets JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - enables direct use in 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters. |
| Propagation Delay (tpd) | 0.5 ns to 6.5 ns - ensures timing-critical sampling within high-speed digital control loops at up to 450 MHz (VCC = 3.3 V). |
| Set-up / Hold Time | tsu = 0.5 ns to 2.5 ns, th = −0.3 ns to +0.5 ns - accommodates tight timing margins in FPGA I/O bridging and microcontroller peripheral synchronization. |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads (<30 pF) without buffering. |
| IOFF Leakage | ±2 μA max at VCC = 0 V - guarantees safe isolation during system power sequencing and partial shutdown. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor IoT edge nodes. |
| Input Tolerance | Inputs withstand 5.5 V regardless of VCC - allows direct connection to 5 V sensors or legacy controllers in mixed-voltage boards. |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 × 1.45 × 0.5 mm; thermal pad not present; pin 1 index located on lower-left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Data input | Asynchronous data source sampled on next CP rising edge; Schmitt-triggered for robustness against slow/noisy signals. |
| 2 (CP) | Clock pulse input | Positive-edge-sensitive trigger; accepts 0–5.5 V swing; determines exact sampling instant for D-to-Q transfer. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output drivers; must be low-impedance for stable switching. |
| 4 (Q) | Data output | Inverted complementary output not provided; Q reflects D state after CP edge; drives downstream logic or bus lines. |
| 5 (n.c.) | No connect | Internally unconnected terminal; must remain floating - no routing or soldering allowed. |
| 6 (VCC) | Supply voltage | Primary power rail; decoupling capacitor (100 nF) required within 3 mm for noise suppression and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | Operates from 1.65 V to 5.5 V - eliminates need for separate voltage translators in multi-rail systems. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V typical - rejects noise on long traces or unshielded sensor lines without external RC filtering. |
| IOFF partial power-down | Outputs disabled when VCC = 0 V - prevents back-current damage during hot-plug or staged power-up sequences. |
| Overvoltage-tolerant inputs | Withstands 5.5 V input regardless of VCC - enables direct interfacing with 5 V peripherals even when powered from 1.8 V. |
| High ESD robustness | HBM >2000 V, CDM >1000 V - reduces field failure risk in manual assembly and handling environments. |
Applications
| Industrial PLC I/O Expansion | Automotive Sensor Signal Conditioning |
|---|---|
Use Scenario: Isolating and synchronizing discrete sensor inputs (e.g., limit switches, proximity detectors) into a microcontroller's GPIO port under noisy factory-floor conditions. IC Role / Device Role / Timing Role: D-type flip-flop acting as a synchronous input synchronizer to eliminate metastability when crossing clock domains between sensor polling and main control loop. Use Value: Guarantees single-cycle capture of asynchronous signals with <6.5 ns tpd at 3.3 V, reducing firmware debounce overhead and improving real-time response. | Use Scenario: Level-shifting and edge-aligning analog-to-digital converter (ADC) ready flags or encoder quadrature pulses before feeding to an ASIL-B microcontroller. IC Role / Device Role / Timing Role: Positive-edge-triggered data latch translating 5 V sensor logic to 3.3 V MCU domain while preserving signal integrity and timing alignment. Use Value: Eliminates external resistor dividers or dedicated level shifters; overvoltage-tolerant inputs accept 5 V pulses directly, saving board area and BOM cost. |
| IoT Edge Node Power Management | Medical Diagnostic Equipment Clock Gating |
Use Scenario: Controlling enable states of peripheral subsystems (e.g., BLE radio, environmental sensor array) based on host processor commands in battery-powered wearables. IC Role / Device Role / Timing Role: Synchronous control register holding wake-up or sleep command until next system clock edge, ensuring deterministic power-state transitions. Use Value: IOFF functionality blocks leakage paths when VCC is removed from subsystems, extending battery life by limiting off-state current to ≤2 μA per channel. | Use Scenario: Gating clock distribution to ultrasound transducer driver ICs during idle periods to reduce dynamic power consumption in portable imaging devices. IC Role / Device Role / Timing Role: Edge-triggered enable latch that starts/stops clock delivery only on clean rising edges, preventing runt pulses or glitches on clock tree branches. Use Value: Sub-1 ns jitter margin and 0.5 ns minimum pulse width support ensure glitch-free clock gating at >200 MHz, maintaining signal fidelity in time-of-flight measurements. |
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 |
|---|---|---|---|
| SN74LVC1G79DBVR | SOT-23-5 package (larger footprint, 2.9 × 1.6 mm); same electrical specs; no n.c. pin - all 5 pins functional. | Better suited for prototyping or low-volume hand-soldered assemblies due to larger pitch and visibility. | Select when board layout allows SOT-23 and manual rework is anticipated; avoid for ultra-dense layouts requiring XSON6 size. |
| 74AUP1G79GW,125 | Lower static current (0.9 μA vs. 4 μA), wider temp range (−40 °C to +125 °C), but reduced drive (±4 mA) and slower speed (12 ns tpd @ 3.3 V). | Optimized for ultra-low-power always-on monitoring nodes rather than high-speed data capture. | Select when nanowatt standby power dominates design priority and timing slack exceeds 10 ns. |
Compared with SN74LVC1G79DBVR and 74AUP1G79GW,125, the 74LVC1G79GM,115 uniquely balances ultra-small XSON6 size, 24 mA drive strength, and 5.5 V input tolerance - making it optimal for space-constrained, mixed-voltage, high-reliability embedded systems where both density and robustness are non-negotiable.

FAQ
Is the 74LVC1G79GM,115 pin-compatible with other 74LVC1G79 variants?
No - the GM variant uses the 6-terminal XSON6 (SOT886) package with a no-connect (n.c.) pin at position 5, whereas GW (TSSOP5) and GV (SC-74A) use 5-pin packages with all pins functional. Physical layout, solder pad geometry, and thermal characteristics differ significantly; redesign is required for substitution.
Does the 74LVC1G79GM,115 support true bidirectional level translation?
No - it provides unidirectional level translation only: D and CP inputs tolerate 5.5 V regardless of VCC, but Q output swings between 0 V and VCC. For bidirectional translation (e.g., I²C), a dedicated bus switch or auto-direction-sensing translator is required.
What is the maximum clock frequency supported at 1.8 V supply?
At VCC = 1.8 V (within JESD8-7 spec), the maximum clock frequency is 160 MHz, limited by propagation delay (9.9 ns max) and minimum pulse width (3.0 ns min). This is verified per Table 8 and applies across −40 °C to +125 °C ambient.
Can the n.c. pin on the XSON6 package be grounded or left floating?
The n.c. pin (position 5) must remain unconnected and floating - it is internally isolated with no bond wire or circuit connection. Grounding or routing it risks mechanical stress on the die, solder bridging, or unintended parasitic coupling; Nexperia explicitly prohibits any connection.
