Product details

Overview

MC74LVX08DTR2 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 voltage-compatible combinational logic buffer in mixed-supply digital control subsystems.

For engineers reviewing the MC74LVX08DTR2 datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance, propagation delay consistency across gates, output drive capability under 3.3 V supply, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The MC74LVX08DTR2 implements four independent 2-input AND functions using advanced CMOS process technology. Its inputs are fully 5 V-tolerant-operable up to 6.5 V-enabling direct connection to legacy 5 V logic without external level shifters while powered from a 3.3 V supply (2.0–3.6 V range).

All four gates share matched propagation delays (tPLH/tPHL ≤ 12.0 ns max at 3.3 V/50 pF) and low output skew (≤1.5 ns), ensuring deterministic timing in synchronous enable/control paths. Input leakage remains ≤±1.0 µA at 3.6 V, and power-down protection prevents back-driving during supply sequencing.

Key Features

Feature	Design Value
5 V-tolerant inputs	Accepts 0–6.5 V input signals while operating from 2.0–3.6 V VCC - eliminates need for discrete level translators in mixed-voltage systems
Low propagation delay skew	≤1.5 ns output-to-output skew ensures synchronized switching across all four gates - critical for enable/control signal fanout

FAQ

What is the maximum input voltage the MC74LVX08DTR2 can tolerate?

The MC74LVX08DTR2 supports DC input voltages from −0.5 V to +6.5 V regardless of VCC level - enabling direct connection to 5 V logic families such as TTL or 74HC while operating from a 3.3 V supply. This 5 V-tolerant feature is built into the input structure and does not require external clamping diodes or resistors. The MC74LVX08DTR2 maintains full functionality and specified timing across this extended input range.

Can the MC74LVX08DTR2 operate reliably at 2.0 V supply?

Yes, the MC74LVX08DTR2 is fully specified down to 2.0 V VCC, with guaranteed VIH = 1.5 V and VIL = 0.5 V at that voltage. Propagation delay increases to 13.5 ns max (CL = 50 pF), but logic thresholds and output drive remain functional. This makes the MC74LVX08DTR2 suitable for battery-powered systems where supply voltage may sag below nominal 3.3 V, and ensures compatibility with wide-VCC microcontrollers and FPGAs.

Does the MC74LVX08DTR2 have power-down protection on its inputs?

Yes, the MC74LVX08DTR2 includes integrated power-down protection that prevents damaging current flow into the VCC rail when inputs are driven high while VCC = 0 V. This feature allows safe operation during partial power-down sequences, hot-swap events, or system reset conditions where input signals may remain active independently of the IC's supply. The MC74LVX08DTR2 meets this requirement without external circuitry.

What is the output drive capability of the MC74LVX08DTR2 at 3.3 V?

At VCC = 3.3 V, the MC74LVX08DTR2 delivers VOH ≥ 2.58 V at IOH = −4 mA and VOL ≤ 0.1 V at IOL = 4 mA - confirming robust drive into standard LS-TTL loads or moderate PCB traces. Each output supports ±25 mA absolute maximum, allowing short-duration peak loading for LED indicators or small MOSFET gates. The MC74LVX08DTR2 maintains these values across −40°C to +85°C.

Is the MC74LVX08DTR2 pin-compatible with other logic families?

Yes, the MC74LVX08DTR2 is pin- and function-compatible with industry-standard quad 2-input AND gates including the 74HC08, 74HCT08, and 74LV08 in both SOIC-14 and TSSOP-14 packages. Its pin assignment matches JEDEC MS-012 (SOIC) and MO-153 (TSSOP) footprints, enabling drop-in replacement in existing designs - provided input voltage tolerance requirements align. The MC74LVX08DTR2 retains identical logic behavior and pinout across all variants.
