Product details
Overview
74LVC541ADB,112 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.
For engineers reviewing the 74LVC541ADB,112 datasheet, 74LVC541ADB,112 pinout, 74LVC541ADB,112 application, or 74LVC541ADB,112 equivalent, key selection criteria include 5 V tolerance on all I/O, dual independent 3-state control, guaranteed operation from −40 °C to +125 °C, and compliance with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.
Technical Context
This device implements eight non-inverting buffers with two separate active-low output enable inputs-OE1 controls Y0–Y3, OE2 controls Y4–Y7-enabling independent bus segment control. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals. The logic family is LVC (Low-Voltage CMOS), optimized for low dynamic power (CPD = 14.4 pF at VCC = 3.3 V) and fast propagation (tpd ≤ 5.1 ns at VCC = 3.3 V, −40 °C to +85 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct interface with 1.2 V, 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. |
| Propagation Delay (tpd) | ≤ 5.1 ns at VCC = 3.3 V - Supports high-speed data routing in memory address/data buses and peripheral interfaces. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging backfeed current during hot-swap or partial system power-down. |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - Rejects noise on slow or unterminated lines (e.g., front-panel switches, sensor inputs). |
| Operating Temperature | −40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces need for external ESD protection in board-level designs. |
Pinout & Package
74LVC541ADB,112 is packaged in SOT339-1 (SSOP20), a 20-lead shrink small outline package with 0.65 mm lead pitch, 7.2 mm body width, and exposed thermal pad (non-soldered by default). Pin 1 index located at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE1 | Active-low enable for outputs Y0–Y3; drives them to high-impedance when HIGH. |
| 2 | VCC | Primary power supply input (1.2 V–3.6 V); decoupling capacitor required near this pin. |
| 3–10 | A0–A7 | Eight buffered data inputs; Schmitt-triggered for noise immunity on all pins. |
| 11–18 | Y0–Y7 | Eight non-inverting 3-state outputs; Y0–Y3 controlled by OE1, Y4–Y7 by OE2. |
| 19 | OE2 | Active-low enable for outputs Y4–Y7; independent of OE1 for segmented bus control. |
| 20 | GND | Ground reference (0 V); must be connected to system ground plane for signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | OE1 and OE2 allow selective isolation of upper/lower 4-bit bus segments without external logic. |
| 5.5 V tolerant I/O | Enables direct connection to legacy 5 V logic or analog sensors without external voltage translators. |
| IOFF partial power-down | Automatically disables outputs and blocks reverse current when VCC = 0 V - critical for hot-plug and battery-backed systems. |
| Schmitt-trigger inputs | Eliminates need for external RC filters on noisy or slow-switching control lines (e.g., reset, enable, interrupt). |
| JEDEC-compliant voltage ranges | Validated for 1.65–1.95 V (JESD8-7A), 2.3–2.7 V (JESD8-5A), and 2.7–3.6 V (JESD8-C/JESD36) operation. |
Applications
| Industrial PLC I/O Expansion | Embedded Microcontroller Bus Interface |
|---|---|
Use Scenario: Isolating and driving 8-bit parallel I/O lines between a 3.3 V ARM Cortex-M controller and legacy 5 V industrial sensors/actuators. IC Role / Device Role / Timing Role: Non-inverting buffer with dual 3-state control acts as a voltage-tolerant bus repeater and segment isolator. Use Value: Eliminates discrete level shifters and reduces BOM count while maintaining timing integrity (tpd ≤ 5.1 ns) across mixed-voltage subsystems. |
Use Scenario: Expanding GPIO capability of a low-power MCU by adding an 8-bit latched I/O port via parallel interface. IC Role / Device Role / Timing Role: Octal buffer provides drive strength (24 mA sink/source) and noise-immune input capture for pushbutton or encoder inputs. Use Value: Schmitt-trigger inputs reject contact bounce and EMI; IOFF prevents backfeed during MCU sleep modes. |
| Memory Address/Data Buffering | Test Equipment Signal Conditioning |
Use Scenario: Driving address lines to multiple SRAM or Flash devices sharing a common bus in a 3.3 V embedded system. IC Role / Device Role / Timing Role: Low-propagation-delay buffer ensures setup/hold timing margins are met across temperature (−40 °C to +125 °C). Use Value: Guaranteed tpd ≤ 6.5 ns over full temperature range enables reliable high-speed memory access up to 100 MHz. |
Use Scenario: Conditioning digital stimulus/response signals in automated test equipment where signal integrity and voltage translation are critical. IC Role / Device Role / Timing Role: Level-translating buffer interfaces FPGA I/O (1.8 V) to DUT test points operating at 5 V TTL levels. Use Value: 5.5 V I/O tolerance and ±24 mA drive capability ensure clean signal edges without external drivers or clamps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC541APWR | TSSOP20 package (SOT360-1); identical electrical specs but different thermal resistance (10.0 mW/K derating above 100 °C). | Higher board density; requires finer-pitch reflow profile; no exposed thermal pad. | Select for space-constrained PCBs where SSOP20 footprint is unavailable. |
| 74LVC244APW,118 | Single OE input (not dual); otherwise identical voltage range, I/O tolerance, and speed. | Lacks independent control of upper/lower 4-bit segments - unsuitable for segmented bus isolation. | Choose only when unified 3-state control suffices and cost reduction is prioritized over flexibility. |
Compared with SN74LVC541APWR and 74LVC244APW,118, the 74LVC541ADB,112 uniquely supports independent segmentation of 8-bit buses via dual OE inputs while retaining the SSOP20 footprint's mechanical robustness and hand-solderability.

FAQ
Can 74LVC541ADB,112 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 guarantees 5.5 V input tolerance across that entire range. At VCC = 1.2 V, VIH is 1.08 V min and VIL is 0.12 V max, while input clamping diodes safely shunt excess voltage to VCC or GND without damage.
What is the function of the IOFF circuit, and when does it activate?
The IOFF circuit activates automatically when VCC = 0 V, disabling all outputs and limiting OFF-state leakage to ±10 μA max. This prevents backflow current from live I/O lines into a powered-down device - essential for hot-swap, battery backup, and multi-rail power sequencing applications.
How does the dual output enable (OE1/OE2) improve system design versus single-OE buffers?
Dual OE inputs let designers isolate upper and lower 4-bit segments independently - e.g., enabling Y0–Y3 for address lines while keeping Y4–Y7 high-Z during data transfer. This eliminates need for additional logic gates or multiplexers in bus arbitration or memory-mapped I/O expansion.
Is the SSOP20 (SOT339-1) package RoHS compliant and lead-free?
Yes. 74LVC541ADB,112 is manufactured in a lead-free, RoHS-compliant SSOP20 package per Nexperia's standard environmental policy. The finish is matte tin, compatible with standard Pb-free reflow profiles (peak temp ≤ 260 °C).
