Product details
Overview
74LVC08AS14-13 from Diodes Incorporated is a quadruple 2-input AND gate logic IC in SO-14 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs, IOFF-enabled partial power-down protection, and 24mA sink capability at 3.3V - used for voltage-level translation and signal gating in mixed-voltage embedded control systems.
For engineers reviewing the 74LVC08AS14-13 datasheet, 74LVC08AS14-13 pinout, 74LVC08AS14-13 application, or 74LVC08AS14-13 equivalent, key selection criteria include input voltage tolerance, IOFF leakage (<20 µA), propagation delay (≤5.5 ns at 3.3V), output drive strength, and SO-14 thermal resistance (θJA TBD).
Technical Context
This device implements four independent positive-logic AND gates (Y = A · B) with rail-to-rail input compatibility up to 5.5V and guaranteed operation down to 1.65V. Its IOFF circuit actively disables outputs during VCC = 0V, preventing back-current flow in partial-power-down systems.
It supports voltage translation between 1.8V, 2.5V, 3.3V, and 5V domains due to asymmetric VIH/VIL thresholds and 5.5V-tolerant I/O. Switching performance is characterized across –40°C to +125°C with tPD as low as 2.6 ns (typ) at 3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input AND gates (Y = A · B) |
| Supply Voltage Range | 1.65V to 5.5V - enables single-supply operation across 1.8V/2.5V/3.3V/5V systems |
| Input Voltage Tolerance | Up to 5.5V - allows interfacing with higher-voltage logic without level shifters |
| IOFF Leakage Current | ≤20 µA at –40°C to +125°C - ensures safe isolation during power-down |
| Output Drive (Sink) | 24mA at VCC = 3.3V - sufficient to drive multiple LVC/LVT inputs or small LEDs |
| Propagation Delay | ≤5.5 ns (max) at VCC = 3.0–3.6V, TA = –40°C to +125°C - supports >100 MHz toggle rates |
| ESD Protection | 2 kV HBM, 1 kV CDM, 200 V MM - exceeds JEDEC JESD22 for robust board handling |
Pinout & Package
74LVC08AS14-13 is housed in a 14-pin SOIC (SO-14) surface-mount package with standard 1.27 mm pitch, 8.53–8.74 mm body length, and 3.80–3.99 mm width per Diodes' outline drawing.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1, 4, 9, 12 | Input A (1A, 2A, 3A, 4A) | First input of each AND gate; 5.5V-tolerant, compatible with 1.65–5.5V logic levels |
| 2, 5, 10, 13 | Input B (1B, 2B, 3B, 4B) | Second input of each AND gate; identical electrical specs to Input A |
| 3, 6, 8, 11 | Output Y (1Y, 2Y, 3Y, 4Y) | Active-high AND result; drives loads up to 24mA sink at 3.3V |
| 7 | GND | Ground reference for all logic and power domains; required for IOFF functionality |
| 14 | VCC | Primary supply rail; powers internal logic and enables IOFF control when active |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Eliminates need for separate voltage regulators in multi-rail systems |
| IOFF partial power-down | Prevents destructive back-current when VCC = 0V while inputs remain biased |
| 5.5V-tolerant I/O | Enables direct connection to 5V microcontrollers or peripherals without external translators |
| Low dynamic power (Cpd = 8.0 pF @ 3.3V) | Reduces switching current and EMI in high-density logic arrays |
| Industrial temperature range (–40°C to +125°C) | Supports deployment in automotive under-hood, industrial PLC, and outdoor equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08APWRE4 (TI) | TSSOP-14 only; identical VCC range, IOFF, and 5.5V tolerance; slightly higher tPD (6.5 ns max @ 3.3V) | No SO-14 option; requires PCB redesign for footprint compatibility | Select if sourcing TI-qualified parts or requiring TI's enhanced traceability documentation |
| 74LVC08AD,118 (Nexperia) | SO-14 package; same logic function and VCC range; lower sink drive (24mA @ VCC ≥ 3.0V only); IOFF leakage ≤10 µA | Better leakage spec but tighter VCC dependency for full drive strength | Prefer for ultra-low-power standby modes where sub-10 µA IOFF is critical |
Compared with SN74LVC08APWRE4 and 74LVC08AD,118, the 74LVC08AS14-13 offers SO-14 availability with balanced drive strength and industrial-temp IOFF performance - making it optimal for cost-sensitive, space-constrained designs requiring proven Diodes reliability and tape-and-reel logistics.

FAQ
Can 74LVC08AS14-13 be used with 1.8V microcontrollers driving 5V peripherals?
Yes. Its 5.5V-tolerant inputs accept 1.8V logic levels while its outputs swing rail-to-rail up to VCC = 5.5V. When powered at 5V, it translates 1.8V-enable signals to 5V-active outputs - provided input VIH min (0.65 × VCC = 3.25V) is met via pull-up or buffered drive.
What happens to outputs during power-down (VCC = 0V)?
The IOFF circuit automatically disables all outputs, limiting leakage to ≤20 µA over –40°C to +125°C. This prevents back-current from live inputs into the unpowered VCC/GND rails - a critical feature for hot-swap and partial-power-down architectures.
Is the SO-14 package RoHS and halogen-free compliant?
Yes. The 74LVC08AS14-13 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes' definition: Br+Cl <1500 ppm, Sb <1000 ppm), with no purposely added lead or restricted substances.
How does propagation delay vary with supply voltage and temperature?
tPD ranges from 9.3 ns (max) at 1.65V/–40°C to 3.9 ns (max) at 3.3V/+125°C. At 3.3V, typical delay is 2.6 ns; maximum is 5.5 ns across –40°C to +125°C - enabling reliable 100+ MHz clocked logic in non-critical timing paths.
