Product details
Overview
74LVC1G08Z-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT553 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial-power-down protection. It performs Boolean Y = A · B and is used for voltage-level shifting and signal gating in portable logic interfaces.
For engineers reviewing the 74LVC1G08Z-7 datasheet, 74LVC1G08Z-7 pinout, 74LVC1G08Z-7 application, or 74LVC1G08Z-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance for mixed-voltage systems, IOFF-enabled power-down isolation, and compact 1.6mm × 1.6mm SOT553 footprint for space-constrained designs.
Technical Context
This device implements standard CMOS positive-logic AND functionality with push-pull output stage, supporting rail-to-rail output swing and TTL-level compatibility. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow between powered and unpowered domains.
Input thresholds scale with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5V), enabling reliable operation across 1.65V–5.5V supply range. Propagation delay is 2.1ns typical at 3.3V, with 4.5ns max over –40°C to +125°C, making it suitable for high-speed digital control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive AND (Y = A · B); enables basic combinatorial signal enable/gating |
| Supply Voltage Range | 1.65V to 5.5V; supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V independent of VCC; allows safe interfacing with higher-voltage signals in mixed-supply systems |
| Output Drive Strength | ±24mA at VCC = 3.3V; sufficient to drive multiple LVC loads or small capacitive traces without buffering |
| IOFF Leakage | ±200μA max at VCC = 0V; ensures robust isolation during partial power-down to prevent bus contention |
| Propagation Delay | 4.5ns max at VCC = 3.3V, –40°C to +125°C; meets timing requirements for sub-100MHz synchronous control logic |
| ESD Protection | HBM >2kV, CDM >1kV, MM >200V; exceeds JEDEC standards for board-level handling and system-level robustness |
Pinout & Package
SOT553 package: ultra-compact 1.6mm × 1.6mm × 0.62mm body with 0.5mm lead pitch and 5-pin configuration (1: A, 2: GND, 3: Y, 4: VCC, 5: B).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First logic input; accepts 0–5.5V signals regardless of VCC level |
| 2 (GND) | Ground Reference | Primary return path for supply and signal currents; must be low-impedance |
| 3 (Y) | Data Output | Push-pull AND result output; sinks or sources up to ±24mA at 3.3V |
| 4 (VCC) | Power Supply | Core supply input (1.65–5.5V); powers internal logic and output stage |
| 5 (B) | Data Input | Second logic input; electrically identical to Pin 1 with same voltage tolerance |
Key Features
| Feature | Design Value |
|---|---|
| Wide-Voltage Operation | 1.65V–5.5V supply range enables drop-in use across legacy and modern logic families without level shifters |
| 5.5V-Tolerant Inputs | Inputs accept up to 5.5V even when VCC = 1.65V, simplifying inter-domain signal routing in multi-rail systems |
| IOFF Partial-Power-Down | Output automatically enters high-impedance state when VCC = 0V, preventing backfeed current into powered subsystems |
| Low Dynamic Power | Typical ICC = 0.1μA at 5.5V; reduces quiescent power in always-on logic monitoring paths |
| Small-Signal Timing | 2.1ns typical tPD at 3.3V supports clean edge propagation in clock-enable and reset-synchronization circuits |

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 | Same logic function and IOFF, but in SOT-23-5 (2.9mm × 1.6mm); 30% larger footprint than SOT553 | Less suitable for ultra-dense wearables or miniaturized IoT modules where board area is constrained | Select when existing layout uses SOT-23-5 or requires higher thermal mass for intermittent high-current loads |
| 74AUP1G08GW,125 | Lower static current (0.9μA typ vs. 0.1μA), wider temp range (–40°C to +125°C), but no IOFF support | Not usable in partial-power-down architectures requiring back-current prevention | Prefer for battery-powered always-on sensors where ultra-low ICC dominates over power-down safety |
Compared with SN74LVC1G08DBVR, 74LVC1G08Z-7 saves 45% board area and improves thermal resistance (θJA = 231°C/W vs. 204°C/W). Versus 74AUP1G08GW, it adds critical IOFF protection for multi-rail systems but trades 0.8μA higher ICC in active state.

FAQ
Can 74LVC1G08Z-7 operate reliably at 1.65V supply?
Yes. The device is fully specified down to 1.65V - all parameters including VOH, VOL, tPD, and IIH/IIL meet datasheet limits at this minimum voltage. Input thresholds scale accordingly (VIH = 0.65×VCC), ensuring correct logic interpretation across the full 1.65–5.5V range.
What is the maximum capacitive load this AND gate can drive?
While not explicitly rated for capacitive load, the ±24mA output drive at 3.3V and 4.5ns max tPD indicate suitability for ≤30pF loads under typical PCB conditions. For heavier loads (e.g., >50pF), add series termination or buffer stages to maintain signal integrity and timing margins.
Does the SOT553 package support reflow soldering per J-STD-020?
Yes. The SOT553 package is qualified for standard lead-free reflow profiles (peak 260°C, 20–40s above 217°C). Thermal resistance data (θJA = 231°C/W) confirms adequate heat dissipation under JEDEC-compliant board layouts with recommended pad dimensions (C = 0.48mm, X/Y = 0.375/0.5mm).
How does IOFF behavior affect system-level power sequencing?
When VCC drops to 0V, IOFF forces the output into high-impedance state regardless of input states, blocking reverse current flow from powered downstream buses (e.g., 3.3V I²C lines) into the unpowered gate. This eliminates risk of unintended power injection and latch-up during controlled shutdown sequences.
