Product details
Overview
74LV08DB,112 from Nexperia is a quad 2-input CMOS AND gate IC operating from 1.0 V to 5.5 V supply, featuring TTL-level input compatibility at VCC = 2.7–3.6 V, typical propagation delay of 7 ns at 3.3 V/15 pF, and guaranteed operation from –40 °C to +125 °C in SO14 (SOT108-1) package - used for digital logic level translation and signal gating in low-voltage microcontroller I/O expansion.
For engineers reviewing the 74LV08DB,112 datasheet, 74LV08DB,112 pinout, 74LV08DB,112 application, or 74LV08DB,112 equivalent, key selection criteria include supply voltage flexibility (1.0–5.5 V), output drive capability (±12 mA), input clamp diodes enabling overvoltage-tolerant interfacing, and industrial temperature grade compliance.
Technical Context
The 74LV08DB,112 implements four independent AND logic functions with Schmitt-trigger–free inputs and push-pull CMOS outputs. Its input clamp diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors - a critical feature for mixed-voltage system interconnects.
It operates across three JEDEC-compliant voltage domains (JESD8-7, JESD8-5, JESD8C) and supports dynamic performance up to 100 MHz at 3.3 V (based on tpd ≤ 9 ns and CPD = 10 pF). Static logic thresholds scale with VCC, ensuring robust noise margins across its full 1.0–5.5 V range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 1.0 V to 5.5 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | 7 ns typical at VCC = 3.3 V, CL = 15 pF - supports >100 MHz toggle rates in synchronous logic paths. |
| Output Drive (IO) | ±12 mA - sufficient to directly drive multiple 74LVC inputs or small capacitive loads (<30 pF) without buffering. |
| Input Clamp Diodes | Integrated - permits safe connection of inputs to voltages up to VCC + 0.5 V using external current-limiting resistors. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded control. |
| Power Dissipation (Ptot) | 500 mW max at Tamb ≤ 100 °C (SO14) - derates linearly at 10.1 mW/K above 100 °C for thermal design margin. |
| ESD Rating (HBM) | >2000 V - exceeds JEDEC JS-001 Class 2, reducing need for external ESD protection in board-level designs. |
Pinout & Package
74LV08DB,112 is supplied in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input per AND gate - accepts TTL- or CMOS-level signals; clamped to VCC/GND. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input per AND gate - identical electrical behavior to A inputs; enables dual-input logic gating. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-HIGH AND output - drives load to VOH ≥ 2.82 V (at VCC = 3.0 V, IO = –6 mA) or VOL ≤ 0.40 V. |
| 7 | GND | Ground reference - must be low-impedance return path; shared by all four gates' internal circuitry. |
| 14 | VCC | Primary supply - powers all gates; decoupling capacitor (100 nF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.0–5.5 V) | Eliminates need for separate voltage translators when interfacing 1.2 V FPGA I/O with 3.3 V peripherals. |
| TTL input compatibility | Accepts standard TTL logic levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at VCC = 2.7–3.6 V - simplifies legacy system upgrades. |
| Input clamp diodes | Enables robust 5 V-tolerant input operation via 10 kΩ series resistor - avoids damage during hot-plug or bus contention. |
| Low ground bounce (<0.8 V) | Minimizes switching noise coupling into shared GND planes - critical for mixed-signal PCB layouts with ADCs or PLLs. |
| High-temperature operation | Guaranteed functionality at +125 °C ambient - suitable for engine control units and power converter monitoring circuits. |
Applications
| Industrial Sensor Interface | Microcontroller I/O Expansion |
|---|---|
|
Use Scenario: Isolating and gating analog sensor enable signals before routing to ADC reference buffers. IC Role / Device Role / Timing Role: Quad AND gate performing synchronized channel enable/disable based on MCU GPIO and fault flags. Use Value: Prevents spurious ADC conversions during sensor warm-up or fault recovery by requiring both clock and valid-data signals. |
Use Scenario: Expanding limited GPIO count on an ARM Cortex-M0+ MCU to drive eight discrete LED indicators. IC Role / Device Role / Timing Role: Logic-level combiner translating two MCU pins into four independent active-HIGH LED controls. Use Value: Reduces firmware overhead by offloading simple combinational logic from CPU to hardware, freeing cycles for real-time tasks. |
| Legacy Bus Arbitration | Power Sequencing Control |
|
Use Scenario: Resolving bus grant conflicts between two 8-bit microcontrollers sharing a common SRAM data bus. IC Role / Device Role / Timing Role: Enabling memory access only when both BUSREQ and BUSACK signals are asserted simultaneously. Use Value: Ensures deterministic bus ownership handoff without metastability risk - no external synchronizers needed. |
Use Scenario: Controlling startup order of three DC-DC converters (1.2 V, 2.5 V, 3.3 V) in an FPGA power management subsystem. IC Role / Device Role / Timing Role: AND-ing delayed reset signals to generate sequenced enable pulses with fixed timing dependencies. Use Value: Guarantees strict monotonic voltage ramp-up to prevent FPGA configuration corruption during power-on. |
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 |
|---|---|---|---|
| SN74LVC08APWR | Wider VCC range (1.65–5.5 V); lower ICC (10 μA max); no input clamp diodes. | Lacks overvoltage-tolerant inputs - requires external protection if interfacing to >VCC signals. | Select when lowest static power and tight 1.65 V minimum VCC are prioritized over input robustness. |
| 74AHC08PW,118 | Higher speed (tpd = 5.2 ns @ 5 V); higher VCC max (5.5 V); same SO14 package. | Not specified for –40 °C to +125 °C - rated only to +85 °C, limiting use in extended-temperature environments. | Select when maximum speed at 5 V is critical and industrial temperature range is not required. |
Compared with SN74LVC08APWR and 74AHC08PW,118, the 74LV08DB,112 uniquely combines 1.0 V operation, integrated input clamps, and full –40 °C to +125 °C qualification - making it the only option for ultra-low-voltage, overvoltage-resilient, high-temperature logic gating.

FAQ
Can 74LV08DB,112 operate reliably at 1.2 V supply?
Yes. The device is fully specified down to VCC = 1.0 V, with guaranteed logic functionality, VIH/VIL thresholds scaling proportionally, and tpd ≤ 45 ns at 1.2 V. Static characteristics (VOH/VOL, II) are validated across –40 °C to +125 °C at this voltage, making it suitable for ultra-low-power battery-backed systems.
Does 74LV08DB,112 require external pull-up resistors on inputs?
No. Inputs are CMOS-compatible with high-impedance (≤1.0 μA leakage) and internally clamped. Pull-ups are unnecessary unless implementing wired-OR logic or open-drain emulation - in which case external resistors must respect the ±20 mA input clamp current limit.
What is the maximum capacitive load the outputs can drive?
Each output is characterized up to 15 pF (tpd test condition) and supports sustained 12 mA sink/source. For loads >30 pF, propagation delay increases linearly (~0.1 ns/pF), and ground/power bounce may exceed specification - add local series termination or buffer stages for >50 pF loads.
Is 74LV08DB,112 pin-compatible with older 74LS08 variants?
No. While functional equivalence exists, pinout differs: 74LS08 uses 14-pin DIP with VCC on pin 14 and GND on pin 7, but 74LV08DB,112 places VCC on pin 14 and GND on pin 7 - same physical location. However, LS-series lacks input clamps and cannot tolerate VCC < 4.5 V, so direct substitution risks undervoltage failure or input damage.
