Product details
Overview
74LVCE1G08SE-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT353 package, operating from 1.4V to 5.5V supply, with 5.5V-tolerant inputs, ±24mA output drive at 3.3V, and IOFF-enabled partial power-down protection. It performs Boolean Y = A • B logic for voltage-level shifting and mixed-voltage interfacing in portable electronics.
For engineers reviewing the 74LVCE1G08SE-7 datasheet, 74LVCE1G08SE-7 pinout, 74LVCE1G08SE-7 application, or 74LVCE1G08SE-7 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance, IOFF leakage <10μA, propagation delay ≤2.9ns at 3.3V/15pF, and SOT353 thermal resistance (371°C/W).
Technical Context
This device implements standard totem-pole CMOS output architecture with dual-rail input tolerance and active IOFF circuitry that disables output during power-down to prevent backflow current. Its logic function strictly follows Y = A AND B with no inversion or enable control.
Characterized across five supply voltages (1.5V–5V), it delivers sub-3ns propagation delay at 3.3V/15pF and maintains valid VIH/VIL thresholds across all VCC ranges-e.g., VIH = 0.65×VCC at 1.4–1.95V and 0.7×VCC at 4.5–5.5V-enabling robust interoperability in heterogeneous voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 5.5V - supports direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection of 5V signals to lower-VCC systems (e.g., 1.8V host) without external clamping. |
| Output Drive Strength | ±24mA at 3.3V - drives multiple LVC/LVCE loads or short PCB traces without buffering. |
| Propagation Delay | ≤2.9ns at VCC = 3.3V, CL = 15pF - enables reliable operation in high-speed digital control paths up to ~170MHz toggle rate. |
| IOFF Leakage Current | <10μA at VI/VO = 5.5V - prevents damaging back-current during hot-insertion or partial power-down sequences. |
| ESD Robustness | 2000V HBM, 200V MM - exceeds JEDEC JESD22-A114/A115 requirements for handling in automated assembly environments. |
Pinout & Package
SOT353 (SC-70-5) package: 5-pin surface-mount, 1.25mm × 2.1mm footprint, 0.65mm pitch, 0.9–1.0mm height, JEDEC MO-203AA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Primary logic input; accepts 0–5.5V regardless of VCC; internally terminated to VCC/GND via ESD diodes. |
| 2 | B | Secondary logic input; electrically identical to Pin 1; both inputs share same VIH/VIL thresholds. |
| 3 | GND | Ground reference for internal circuitry and output stage; must be connected before VCC during power sequencing. |
| 4 | Y | CMOS totem-pole output; sinks or sources up to ±24mA at 3.3V; exhibits rail-to-rail swing (0V to VCC). |
| 5 | Vcc | Power supply input; regulates internal biasing; IOFF activation occurs when Vcc = 0V while inputs/outputs remain biased. |
Key Features
| Feature | Design Value |
|---|---|
| Extended VCC range (1.4–5.5V) | Enables use in battery-powered devices with decaying supply (e.g., 1.5V alkaline) and legacy 5V subsystems. |
| 5.5V-tolerant inputs | Eliminates need for external resistors or translators when interfacing 5V sensors/microcontrollers to low-VCC FPGAs. |
| IOFF partial power-down | Prevents bus contention and latch-up during sleep mode by disabling Y output while inputs remain high-Z. |
| Low dynamic power (Cpd = 26pF @ 3.3V) | Reduces switching current in high-frequency clock distribution or address decoding, lowering system-level heat dissipation. |
| Green packaging (Br/Sb-free) | Complies with RoHS Directive 2002/95/EC and Diodes Inc.'s halogen-free material specification AP02001. |
Applications
| Mobile Device Power Sequencing | USB Host Interface Logic |
|---|---|
Use Scenario: Coordinating enable signals between baseband processor, PMIC, and peripheral ICs during boot and suspend/resume cycles. IC Role / Device Role / Timing Role: AND gate combining reset and power-good signals to generate synchronized enable pulses for voltage rails. Use Value: Ensures strict sequencing compliance (e.g., VDD_IO before VDD_CORE) using only one logic gate with 5.5V-tolerant inputs tied to 3.3V PMIC outputs. |
Use Scenario: Validating USB enumeration readiness by gating D+ pull-up enable with host controller's USB_EN signal. IC Role / Device Role / Timing Role: Positive AND gate ensuring D+ line is pulled up only when both USB_EN and VBUS are asserted. Use Value: Prevents false enumeration during hot-plug by requiring dual confirmation, leveraging 1.4V minimum VCC to operate from USB 3.3V VBUS directly. |
| Industrial Sensor Signal Conditioning | IoT Edge Node Wake-Up Control |
Use Scenario: Combining analog comparator output and microcontroller wake signal to activate ADC sampling only when both conditions are met. IC Role / Device Role / Timing Role: Level-shifting AND gate translating 5V comparator output to 1.8V MCU input domain while preserving timing integrity. Use Value: Achieves sub-3ns propagation delay at 1.8V supply, enabling precise time-windowed sampling without added latency from discrete translators. |
Use Scenario: Enabling RF transceiver power-on only when motion sensor trigger and low-battery flag are simultaneously active. IC Role / Device Role / Timing Role: Low-power logic gate operating at 1.4V standby supply, consuming <10μA ICC while monitoring two asynchronous event sources. Use Value: Reduces quiescent current by >90% versus standard LVC gates, extending coin-cell battery life in always-on edge nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Wider VCC range (1.65–5.5V); no 1.4V operation; IOFF not specified; 32mA drive at 3.3V. | Lacks true 1.4V compatibility and guaranteed IOFF - unsuitable for ultra-low-voltage battery systems or hot-swap designs. | Select when higher drive strength is required and 1.4V operation is unnecessary. |
| 74AUP1G08GW,125 | NXP variant: 0.8–3.6V VCC; 2.4ns tPD at 3.0V; 4mA drive at 3.0V; no 5.5V input tolerance. | Cannot accept 5V inputs - requires external clamping for mixed-voltage interfaces; limited to sub-3.6V systems. | Select for ultra-low-power (<1μA ICC) applications where 5V tolerance is irrelevant and VCC ≤3.3V. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the 74LVCE1G08SE-7 uniquely supports 1.4V operation, 5.5V input tolerance, and guaranteed IOFF - making it the only choice for battery-decay-aware, mixed-voltage, and hot-pluggable designs requiring single-gate logic integrity.

FAQ
What is the minimum supply voltage at which 74LVCE1G08SE-7 guarantees correct logic operation?
The device is fully characterized down to 1.4V VCC per Recommended Operating Conditions. At this voltage, VIH = 0.65×VCC = 0.91V and VIL = 0.35×VCC = 0.49V, with propagation delay ≤7.2ns (CL = 15pF). Data retention remains valid at 1.2V, but functional operation requires ≥1.4V.
Can 74LVCE1G08SE-7 safely interface a 5V microcontroller GPIO to a 1.8V FPGA input?
Yes - its inputs tolerate up to 5.5V independent of VCC, so a 5V GPIO can drive Pin A or B directly while VCC = 1.8V. The output Y swings 0–1.8V, matching the FPGA's input threshold. No external components are needed for level translation in this direction.
Does 74LVCE1G08SE-7 support hot-swap or partial power-down operation?
Yes - the integrated IOFF circuit automatically disables the output Y when VCC = 0V, limiting leakage current to <10μA even if inputs or outputs are biased to 5.5V. This prevents back-current flow and bus contention during live insertion or subsystem power cycling.
Which package variants share identical logic functionality and pinout with 74LVCE1G08SE-7?
The SOT25 (74LVCE1G08W5-7) and DFN1410 (74LVCE1G08FZ4-7) variants implement identical logic, electrical specs, and pin functions. SOT353 (SE) and SOT25 have identical 5-pin topologies (A-B-GND-Y-VCC); DFN1410 adds NC on Pin 6 but retains same signal mapping on Pins 1–5.
