74LVC1G00GW - Single 2-Input NAND Gate, 1.65V-5.5V | Nexperia
MPN: 74LVC1G00GW ✓ Hoạt động74LVC1G00GW Tóm tắt
An LVC (Low-Voltage CMOS) gate is a sub-family of advanced CMOS logic optimized for operation below 5 V while remaining tolerant of 5 V input signals. Within the broader logic hierarchy, the 74LVC1G00 sits inside the single-gate 74LVC1G family, which in turn belongs to Nexperia's 74LVC logic IC portfolio for power-efficient portable, industrial, and computing designs. Unlike legacy HC/T families, LVC combines low static power consumption with high noise immunity and JEDEC-compliant interface thresholds.
Key features include Schmitt-trigger inputs that tolerate slow or noisy edges, ±24 mA balanced output drive (VCC = 3.0 V) for direct LED or bus loading, latch-up performance exceeding 250 mA per JEDEC JESD78, CMOS low static power consumption, and IOFF partial-power-down support that prevents back-feed currents when the device is unpowered but signal lines remain live. Inputs accept 3.3 V or 5 V logic levels, allowing the part to act as a down-translator in mixed-voltage systems without external level-shifters.
Typical applications span portable and battery-powered electronics, mobile phones and wearables, level shifting between 5 V microcontrollers and 3.3 V peripherals, general-purpose glue logic on FPGA and ASIC boards, and interface buffering in industrial control and white-goods modules. The compact 5-pin TSSOP footprint enables placement near connectors and signal sources for short, clean traces.
When designing with this device, always observe the absolute-maximum VCC of 6.5 V and derate output current above VCC = 4.5 V. Place a 0.1 µF decoupling capacitor as close as possible to VCC pin 5, and unused inputs must be tied to VCC or GND to prevent floating-input quiescent current. The TSSOP-5 footprint is mechanically compatible with Nexperia's entire 74LVC1Gxx single-gate family, simplifying BOM consolidation.

Ứng dụng tiêu biểu
74LVC1G00GW phù hợp cho 6 Áp dụngs: Mixed-Voltage Level Translation (5V to 3.3V), Portable and Battery-Powered Electronics, FPGA / ASIC Glue Logic on Evaluation Boards, Industrial Control and White-Goods Modules, Computing and Server Peripherals (IOFF Safe Insertion), LED Driving and Front-Panel Logic.
Mixed-Voltage Level Translation (5V to 3.3V)
The 74LVC1G00GW is purpose-built for mixed-voltage translation because its inputs accept 3.3 V or 5 V drive while its output swings rail-to-rail at the local VCC. With VCC = 3.3 V and a 5 V CMOS source on input A or B, the gate cleanly down-translates a 5 V high level to 3.3 V logic at output Y. This eliminates external resistor dividers or dedicated level-shifters in 5 V MCU to 3.3 V peripheral interfaces such as SPI, I2C buffers, or GPIO handshaking, and the Schmitt-trigger inputs reject the slow edges typical of long PCB traces or capacitive loads.

Portable and Battery-Powered Electronics
The 74LVC1G00GW's 1.65 V minimum supply, sub-µA quiescent current, and ±24 mA drive make it ideal for portable devices running from a single Li-ion cell (3.0-4.2 V) or two AA cells (2.0-3.2 V). It can implement logic inversion, basic state decoding, or reset conditioning without burdening the battery budget. The TSSOP-5 package keeps the board footprint under 3 mm², leaving room for the smallest wearables, BLE beacons, or wireless sensor nodes where every µA and every mm² matters.

FPGA / ASIC Glue Logic on Evaluation Boards
FPGAs, SoCs, and high-pin-count ASICs almost always need one or two discrete logic gates for reset conditioning, watchdog pulse stretching, clock gating, or hand-shaking between domains. The 74LVC1G00GW delivers that single NAND function with 1.65-5.5 V compatibility, allowing it to sit between the FPGA bank (often 1.8 V) and a 3.3 V peripheral without level-shifter ICs. Its 10.5 ns tpd adds negligible delay to control paths while the small TSSOP-5 footprint places it next to the FPGA without rerouting dense BGA breakouts.

Industrial Control and White-Goods Modules
Industrial PLCs, HVAC controllers, motor-driver boards, and white-goods modules require logic that survives -40 °C to +125 °C, noisy switching environments, and long cable harnesses. The 74LVC1G00GW's Schmitt-trigger action tolerates slow or noisy input edges typical of opto-isolated sensor inputs or relay-coil transients, while JEDEC-compliant latch-up immunity exceeds 250 mA. Its wide 1.65-5.5 V supply lets a single part service 3.3 V logic islands and 5 V sensor interfaces on the same board, reducing BOM complexity.

Computing and Server Peripherals (IOFF Safe Insertion)
Hot-swap, hot-plug, and partial-power-down applications in servers, storage backplanes, and removable-card interfaces need logic that does not back-feed current when its VCC rail is collapsed but the signal line is still driven. The 74LVC1G00GW's IOFF specification guarantees that output leakage stays in the µA range during partial-power-down, protecting upstream devices and meeting the requirements of modern OR-ing and bus-isolation topologies. Its balanced ±24 mA drive can directly switch power-good LEDs or status indicators.

LED Driving and Front-Panel Logic
The ±24 mA output drive at VCC = 3.0 V lets the 74LVC1G00GW sink or source a small indicator LED directly without a series driver transistor, simplifying front-panel logic on consumer devices and appliances. By using a NAND gate instead of a simple inverter, the engineer can implement blink patterns, fault latches, or status-AND logic in a single IC. The TSSOP-5 footprint sits next to the LED without crowding the front-panel flex, and the part's 5 V tolerance protects against back-feeds from external connectors.

Ghi chú thiết kế
Place a 0.1 µF X7R ceramic decoupling capacitor as close as possible to the VCC pin (pin 5), keeping the trace short and wide to minimize inductance. Use a ground via adjacent to pin 3 (GND) to provide a low-impedance return path. For TSSOP-5 (SOT-353) land patterns, follow the JEDEC MO-193 footprint: pad pitch 0.65 mm, pad width 0.3-0.4 mm. Avoid routing noisy switching traces under the IC; keep digital inputs short or series-terminated to prevent reflections that the Schmitt-trigger can mask but not eliminate.
Do not leave unused NAND inputs floating - tie each unused input to VCC or GND through a low-impedance path to prevent shoot-through current and unstable output. Do not exceed the absolute maximum VCC of 6.5 V; transients from hot-plug events or inductive loads must be clamped. Above VCC = 4.5 V, derate output current per the datasheet curve. The 74LVC1G00GW is not a buffered-output variant - if you need a three-state output, use the 74LVC1G125GW instead.
Schmitt-trigger inputs give hysteresis of typically 0.5-0.9 V, allowing reliable operation with input rise/fall times up to several hundred ns. However, very slow edges combined with capacitive loading can still cause output oscillation; if rise times exceed 200 ns, add a small series resistor (100 Ω) at the input or accelerate the edge upstream. For long PCB traces carrying 5 V signals into a 3.3 V VCC domain, place the gate within 50 mm of the source to limit radiated emissions and crosstalk.
