Product details
Overview
74LVC541AD,118 from Nexperia is an octal 3-state buffer/line driver with dual output enables (OE1, OE2), 1.2 V to 3.6 V supply operation, 5.5 V tolerant inputs/outputs, and Schmitt-trigger inputs for noise immunity. It serves as a level translator in mixed-voltage systems (e.g., interfacing 3.3 V microcontrollers to 5 V peripherals) and supports partial power-down via IOFF circuitry.
For engineers reviewing the 74LVC541AD,118 datasheet, 74LVC541AD,118 pinout, 74LVC541AD,118 application, or 74LVC541AD,118 equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual independent output enables, guaranteed operation from −40 °C to +125 °C, and SO20 package compatibility with legacy 74-series footprints.
Technical Context
This device implements eight non-inverting CMOS buffers with two separate active-low 3-state enable controls, allowing independent gating of two groups of outputs. Its IOFF circuitry actively disables outputs during power-down to prevent backflow current, meeting JEDEC JESD8-7A/5A/C and JESD36 standards across 1.65–3.6 V supply ranges.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals such as mechanical switch inputs or long PCB traces. Propagation delay is 2.9 ns typical (VCC = 3.3 V), with enable/disable times under 7 ns, supporting high-speed bus buffering in industrial control and instrumentation interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - Enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| I/O voltage tolerance | −0.5 V to +5.5 V - Allows safe connection to 5 V buses while powered from 3.3 V or lower supplies. |
| Operating temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |
| Propagation delay | 2.9 ns typ. (VCC = 3.3 V) - Supports >100 MHz data rates in synchronous bus applications. |
| IOFF leakage | ±10 μA max. (VCC = 0 V) - Prevents damaging back-current when one side of a bus is unpowered. |
| Input hysteresis | ~0.3 V (VCC = 3.3 V) - Rejects noise on slow-switching signals like reset lines or sensor outputs. |
| Output drive strength | ±24 mA (VCC = 3.0 V) - Drives 50 Ω transmission lines or multiple 74LVC inputs without external buffers. |
Pinout & Package
74LVC541AD,118 uses the SO20 (SOT163-1) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm lead pitch, gull-wing leads. Pin 1 index located at top-left corner with notch marking orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable 1 | Controls Y0–Y7 outputs; LOW enables, HIGH places outputs in high-impedance state. |
| 2–9 (A0–A7) | Data inputs | Non-inverting input terminals for corresponding Yn outputs; accept 0–5.5 V signals. |
| 10 (GND) | Ground reference | 0 V return path for all internal circuitry and I/O; must be connected to system ground plane. |
| 11–18 (Y0–Y7) | Buffered outputs | 3-state outputs mirroring A0–A7; driven only when OE1 and OE2 are both LOW. |
| 19 (OE2) | Active-low output enable 2 | Second enable input; both OE1 and OE2 must be LOW for outputs to drive. |
| 20 (VCC) | Power supply | Primary supply rail (1.2–3.6 V); decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | OE1 and OE2 must both be asserted LOW to activate outputs - enables flexible bus arbitration and hot-swap isolation. |
| 5.5 V tolerant I/O | Inputs and outputs withstand up to +5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage designs. |
| IOFF partial power-down | Outputs automatically enter high-Z when VCC = 0 V - prevents back-current damage during system sleep or hot-plug events. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at 3.3 V supply - rejects EMI and contact bounce on control lines without external RC filtering. |
| JEDEC-compliant voltage ranges | Fully specified per JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across standard logic families. |

FAQ
Can 74LVC541AD,118 operate with a 1.2 V supply and still tolerate 5 V inputs?
Yes. The device is fully specified from 1.2 V to 3.6 V supply, and its inputs are overvoltage tolerant up to +5.5 V regardless of VCC level. This allows safe interfacing of 1.2 V logic domains with legacy 5 V buses without external protection components.
What is the function of the dual output enables (OE1 and OE2)?
Both OE1 and OE2 must be driven LOW simultaneously to enable the Y0–Y7 outputs. If either enable is HIGH, all outputs enter high-impedance state. This dual-control architecture provides redundancy and enables hierarchical bus arbitration schemes in multi-master systems.
Does the SO20 package (SOT163-1) support automated optical inspection (AOI) after reflow?
Yes. The gull-wing leads of the SO20 package provide full solder joint visibility for AOI systems. Lead coplanarity is guaranteed ≤0.1 mm, and the 1.27 mm pitch meets IPC-A-610 Class 2/3 requirements for automated inspection and functional testing in high-reliability manufacturing.
How does the IOFF feature protect the device during partial power-down?
When VCC = 0 V, the IOFF circuitry disables all output drivers and isolates the I/O pins, limiting back-current to ±10 μA maximum. This prevents reverse current flow from powered 5 V buses into unpowered sections of the system - a critical safeguard in hot-swap and modular power architectures.
