Product details
Overview
MC74LVX08DTG from onsemi is a quad 2-input AND gate IC designed for level-shifting logic interfacing between 3.0 V and 5.0 V systems, featuring 5 V-tolerant inputs (up to 6.5 V), 4.8 ns typical propagation delay at 3.3 V, ±25 mA output drive, and operation across −40°C to +85°C. It serves as a high-speed, low-power combinational logic element in mixed-voltage digital control paths.
For engineers reviewing the MC74LVX08DTG datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance, propagation delay consistency across all four gates, output drive capability under 3.3 V supply, and compatibility with SOIC-14 and TSSOP-14 footprints in space-constrained industrial control modules.
Technical Context
The MC74LVX08DTG implements four independent 2-input AND functions in a single monolithic CMOS device, with inputs rated for DC voltages up to 6.5 V - enabling direct connection to 5 V signal sources while powered from a 3.3 V rail. Its balanced tPLH/tPHL delays ensure deterministic timing across all gates.
It features power-down input protection, latch-up immunity exceeding 300 mA, and ESD robustness >2000 V HBM. The device operates within 2.0–3.6 V VCC, supports 15 pF and 50 pF load conditions, and delivers VOL ≤ 0.1 V and VOH ≥ 2.58 V at 4 mA load under 3.3 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - Enables use in modern low-voltage embedded systems without level shifters. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - Allows direct interface with legacy 5 V logic without external clamping. |
| tPD (Typ) | 4.8 ns at VCC = 3.3 V, CL = 15 pF - Supports >100 MHz toggle rates in synchronous logic paths. |
| IOUT (per pin) | ±25 mA - Sufficient to drive multiple 74-series inputs or small LED indicators directly. |
| Operating Temp | −40°C to +85°C - Qualified for industrial-grade temperature operation without derating. |
| ICC (Max) | 2.0 µA at TA = 25°C - Enables ultra-low static power in battery-backed or always-on subsystems. |
| VOH / VOL | ≥2.58 V / ≤0.1 V at IOL = 4 mA - Ensures noise margin >0.7 V in 3.3 V LVTTL-compatible interfaces. |
Pinout & Package
TSSOP-14 package (Case 948G), 5.0 mm × 4.4 mm body, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | A0–A3 (Input A) | First input of each AND gate; 5 V-tolerant, accepts 0–6.5 V signals regardless of VCC. |
| 2, 5, 12, 9 | B0–B3 (Input B) | Second input of each AND gate; identical voltage tolerance and loading characteristics as A pins. |
| 3, 6, 11, 8 | O0–O3 (Output) | CMOS push-pull outputs; rail-to-rail swing referenced to VCC, capable of sourcing/sinking ±25 mA. |
| 7 | GND | Ground reference for all internal circuitry and output drivers; must be low-impedance for noise control. |
| 14 | VCC | Primary power supply (2.0–3.6 V); powers all four gates and output stages; decoupling required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V–Tolerant Inputs | Enables seamless integration into mixed-voltage systems without external level translators or resistive dividers. |
| 4.8 ns Propagation Delay | Ensures minimal timing skew across all four gates, critical for synchronized enable/control bus applications. |
| Power-Down Input Protection | Prevents back-driving and current leakage when VCC = 0 V, supporting hot-swap and partial-power-down modes. |
| Low Dynamic Noise (VOLP ≤ 0.5 V) | Reduces crosstalk in dense PCB layouts where multiple logic devices share supply/ground planes. |
| Latch-Up Immunity >300 mA | Guarantees robust operation under transient overvoltage or ESD events without destructive failure. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

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), but input tolerance limited to VCC + 0.5 V - requires external clamping for 5 V inputs. | Best suited for single-supply 3.3 V or 5 V systems without mixed-voltage interfacing needs. | Select when system uses only one logic voltage and higher ESD rating (4 kV HBM) is prioritized. |
| 74AUP1G08GW,125 | Single-gate variant in SC-70 package; lower ICC (0.9 µA), but no 5 V input tolerance and only one AND function per unit. | Applicable only in ultra-low-power, space-constrained designs where quad integration is not required. | Select only when board area is critical and system architecture allows distributed single-gate placement. |
Compared with SN74LVC08APWR and 74AUP1G08GW,125, the MC74LVX08DTG uniquely supports true 5 V-tolerant inputs on a 3.3 V supply - making it the only option among the three that eliminates external level-shifting components in mixed-voltage industrial control designs.

FAQ
What is the maximum input voltage the MC74LVX08DTG can tolerate?
The MC74LVX08DTG supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This 5 V–tolerant capability allows direct connection to 5 V logic sources even when powered from a 3.3 V supply - a key feature confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does the MC74LVX08DTG require external pull-up or pull-down resistors on unused inputs?
No, the MC74LVX08DTG does not require external pull-up or pull-down resistors on unused inputs. Its inputs include internal power-down protection and exhibit low leakage (±1.0 µA max), allowing floating inputs to remain in a high-impedance state without affecting device behavior or increasing ICC.
Can the MC74LVX08DTG operate reliably at 2.0 V VCC?
Yes, the MC74LVX08DTG is fully specified down to 2.0 V VCC per the Recommended Operating Conditions table. At this minimum supply, VIH remains 1.5 V and VOL stays ≤0.44 V at 4 mA load - ensuring functional compatibility with 1.8 V–2.5 V logic families in ultra-low-power systems.
Is the MC74LVX08DTG pin-compatible with standard 74HC08 or 74LS08 devices?
The MC74LVX08DTG shares identical pinout and logic function with industry-standard quad 2-input AND gates including 74HC08 and 74LS08 in SOIC-14 and TSSOP-14 packages. However, its 5 V–tolerant inputs and 3.3 V–optimized speed/power profile differentiate its electrical behavior - confirming functional compatibility but not full electrical drop-in replacement in all legacy 5 V systems.
What package variants are available for the MC74LVX08DTG?
The MC74LVX08DTG is manufactured in TSSOP-14 (Case 948G) with DT suffix, as indicated in the Ordering Information section. While the same die is also offered in SOIC-14 (D suffix), the DTG marking specifically denotes the Pb-free, RoHS-compliant TSSOP-14 package with 0.65 mm pitch and 5.0 mm × 4.4 mm footprint.
