Product details
Overview
74LVC1G38GS,132 from Nexperia is a single 2-input NAND gate with open-drain output, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates across 1.65 V to 5.5 V supply. Used in I²C bus pull-up control, mixed-voltage interface buffering, and reset signal conditioning.
For engineers reviewing the 74LVC1G38GS,132 datasheet, 74LVC1G38GS,132 pinout, 74LVC1G38GS,132 application, or 74LVC1G38GS,132 equivalent, this device delivers verified open-drain drive capability (±24 mA at 3.0 V), JEDEC-compliant voltage tolerance (5 V input-compatible), -40 °C to +125 °C operation, and XSON6 package compatibility with SOT1202 footprint.
Technical Context
The 74LVC1G38GS implements standard NAND logic with true open-drain output-no internal pull-up-requiring external termination for HIGH-level assertion. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow-rising signals like RC-reset networks or long PCB traces.
IOFF circuitry actively disables output leakage when VCC = 0 V, preventing backfeed current in hot-swap or partial-power-down systems. Input voltage range extends to 5.5 V independent of VCC, supporting direct connection to 5 V microcontroller GPIOs while powered from 1.8 V or 3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input NAND with open-drain output - requires external pull-up for HIGH state; enables wired-AND and I²C-style bus sharing. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-supply operation across low-voltage microcontrollers and legacy 5 V peripherals. |
| Input Voltage Tolerance | 0 V to 5.5 V regardless of VCC - allows direct interfacing with 5 V outputs while powered from 1.8 V/2.5 V/3.3 V rails. |
| Output Drive Strength | ±24 mA sink/source at VCC = 3.0 V - sufficient to drive 10–20 pF loads with <5.7 ns propagation delay (VCC = 3.0–3.6 V). |
| IOFF Leakage | ±2 μA max at VCC = 0 V - prevents damaging backflow current during system power sequencing or hot insertion. |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly. |
Pinout & Package
XSON6 package (SOT1202): 1.0 mm × 1.0 mm × 0.35 mm body, no leads, 6-terminal surface-mount with side-wettable flanks optional (not present in GS variant); thermal pad absent; pin 1 index located at lower-left corner below marking code "YB".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data input 1 | Schmitt-triggered; accepts 0–5.5 V regardless of VCC; enables noise-tolerant signal conditioning. |
| B | Data input 2 | Identical to Pin A; dual-input NAND requires both HIGH to assert LOW on Y. |
| GND | Ground reference | 0 V return path for all internal logic and output current; must be low-impedance for stable switching. |
| n.c. | No connect | Terminal 5 is unconnected internally; must remain floating or grounded per layout best practice. |
| VCC | Power supply | Supplies core logic; IOFF activates automatically when VCC = 0 V to isolate output. |
| Y | Open-drain output | Active-LOW only; requires external pull-up resistor to define HIGH voltage level and bus speed. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Enables use in battery-powered IoT nodes (1.8 V), industrial PLCs (3.3 V), and legacy 5 V subsystems without level shifters. |
| 5 V tolerant inputs | Eliminates need for discrete resistive dividers when interfacing with 5 V MCU GPIOs or sensors. |
| Schmitt-trigger inputs | Provides 0.3 V typical hysteresis at 3.3 V, rejecting EMI and enabling reliable detection of slow-rising reset or enable signals. |
| IOFF partial power-down | Guarantees sub-2 μA leakage when VCC = 0 V, protecting downstream circuits during firmware updates or modular power cycling. |
| Open-drain architecture | Supports wired-AND logic, multi-master bus arbitration (e.g., I²C), and flexible voltage translation via external pull-up selection. |
Applications
| Industrial Sensor Interface | I²C Bus Level Translation |
|---|---|
Use Scenario: Interfacing a 5 V analog sensor's digital alert output to a 3.3 V microcontroller's interrupt pin. IC Role / Device Role / Timing Role: Logic-level translator and noise filter; converts 5 V active-HIGH alert to 3.3 V compatible active-LOW interrupt using open-drain pull-down. Use Value: Eliminates external voltage divider and Schmitt buffer ICs; reduces BOM count and board area by 2 components. | Use Scenario: Connecting a 3.3 V master MCU to 5 V slave peripherals on shared I²C bus. IC Role / Device Role / Timing Role: Bidirectional level shifter element; open-drain Y pins tied together with pull-ups to 5 V, inputs driven by 3.3 V master outputs. Use Value: Enables interoperability without dedicated level-shifting ICs; maintains I²C timing compliance up to 400 kHz. |
| Reset Signal Conditioning | Hot-Swap Power Sequencing |
Use Scenario: Debouncing and synchronizing a mechanical pushbutton reset signal before feeding to FPGA configuration logic. IC Role / Device Role / Timing Role: Schmitt-triggered NAND used as inverter with RC network; provides clean, glitch-free reset assertion. Use Value: Replaces discrete RC + inverter solution; ensures monotonic transition and eliminates metastability risk. | Use Scenario: Controlling power-enable sequencing for a hot-pluggable module where main rail powers down before auxiliary supplies. IC Role / Device Role / Timing Role: Gate controlling enable line to downstream LDO; IOFF blocks reverse current flow when main VCC collapses. Use Value: Prevents backfeeding into failed or disconnected modules; avoids latch-up and damage during live insertion/removal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G00GV,125 | Push-pull output (not open-drain); identical VCC range, IOFF, and Schmitt inputs. | Cannot perform wired-AND or I²C bus sharing; unsuitable for multi-drop or level-translating configurations. | Select only when active-HIGH/LOW push-pull drive is required and bus arbitration is unnecessary. |
| SN74LVC1G38DBVR | Same logic function and open-drain output, but in SOT-23-5 (DBV) package; slightly higher ICC (max 10 μA vs 4 μA). | Larger footprint (2.92 × 1.6 mm vs 1.0 × 1.0 mm); less suitable for ultra-dense portable designs. | Prefer when existing SOT-23 land pattern exists or hand-soldering is required; avoid for space-constrained layouts. |
Compared with 74LVC1G38GV and SN74LVC1G38DBVR, the 74LVC1G38GS,132 offers the smallest footprint (1.0 mm²), lowest quiescent current (4 μA max), and native compatibility with high-density automated assembly-making it optimal for wearables, edge AI sensors, and miniaturized industrial controllers.

FAQ
What is the maximum sink current capability of the 74LVC1G38GS,132 at 3.3 V supply?
The 74LVC1G38GS,132 guarantees ±24 mA output drive at VCC = 3.0 V, with VOL ≤ 0.55 V under 24 mA sink load. At 3.3 V, typical sink current remains ≥22 mA with VOL < 0.6 V per datasheet Table 7, enabling direct drive of LEDs, small relays, or standard logic fan-out loads.
Can the 74LVC1G38GS,132 be used without an external pull-up resistor?
No. As an open-drain device, the 74LVC1G38GS,132 cannot assert a HIGH output state without an external pull-up resistor. The Y pin floats when inactive; omission of the pull-up results in undefined logic levels and bus contention in multi-drop configurations.
Does the 74LVC1G38GS,132 support hot-plug operation with IOFF enabled?
Yes. The IOFF circuit activates automatically when VCC drops to 0 V, limiting output leakage to ±2 μA maximum. This prevents back-current flow from powered downstream circuits into the unpowered gate, satisfying hot-plug safety requirements in modular power architectures.
How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?
Schmitt-trigger inputs provide hysteresis-typically 0.3 V at 3.3 V supply-so the rising and falling input thresholds differ. This prevents multiple toggles during slow or noisy signal transitions, eliminating glitches on reset lines, manual switches, or long-trace sensor outputs without additional RC filtering.
