Product details
Overview
74LVC541ADB,118 from Nexperia is an octal 3-state buffer/line driver with dual output enables (OE1, OE2), 5 V-tolerant I/O, and Schmitt-trigger inputs for noise immunity. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features IOFF partial power-down protection. Used in bus interface, memory address latching, and level-shifting applications in industrial control and embedded peripherals.
For engineers reviewing the 74LVC541ADB,118 datasheet, 74LVC541ADB,118 pinout, 74LVC541ADB,118 application, or 74LVC541ADB,118 equivalent, key selection criteria include 5 V-tolerant input voltage range (−0.5 V to +5.5 V), propagation delay ≤5.1 ns at 3.3 V, IOFF leakage <±10 μA at VCC = 0 V, and −40 °C to +125 °C operating temperature.
Technical Context
This device implements dual independent 3-state enable logic: OE1 and OE2 must both be LOW to drive outputs; either HIGH forces all eight Yn outputs into high-impedance state. Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV up to 20 ns/V at 2.3–2.7 V), enabling robust operation in noisy environments.
The IOFF circuit actively disables outputs during power-down by disconnecting internal paths when VCC = 0 V, preventing backflow current - critical for hot-swap and partial-power-down system architectures. Input clamping diodes support 5.5 V absolute max input voltage regardless of VCC level.
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. |
| Input 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 (An→Yn) | ≤5.1 ns at VCC = 3.3 V - Supports >100 MHz data rates in buffered address/data paths. |
| IOFF Leakage Current | <±10 μA at VCC = 0 V - Prevents damaging back-current during system power sequencing or hot insertion. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and telecom base station interfaces. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces need for external transient suppression in board-level ESD zones. |
| Power Dissipation Capacitance | 14.4 pF at VCC = 3.3 V - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design. |
Pinout & Package
74LVC541ADB,118 uses the SOT339-1 (SSOP20) package: 20-pin shrink small outline plastic package, 0.65 mm pitch, 7.2 mm × 5.3 mm body size, 1.75 mm height. Pin 1 index located at top-left corner with notch marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-LOW dual output enables - both must be LOW for Y0–Y7 drivers to be active; either HIGH places all outputs in high-Z. |
| 2–9 | A0–A7 | Buffer input terminals - Schmitt-trigger inputs tolerate slow edges and reject noise below hysteresis threshold (~0.3 V typical). |
| 10 | GND | Ground reference - decoupling capacitor must be placed within 5 mm of pin for stable switching performance. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - capable of sinking 24 mA or sourcing 24 mA at VCC = 3.3 V with defined VOH/VOL. |
| 20 | VCC | Supply voltage input - requires local 100 nF ceramic bypass capacitor connected directly to GND pin 10. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state enables | OE1 and OE2 provide redundant or split-bus control - allows selective isolation of two 4-bit groups or full 8-bit disable via OR logic. |
| 5 V-tolerant I/O on 1.2–3.6 V supply | Eliminates external level translators in mixed-voltage systems - reduces BOM count and PCB area in FPGA/CPU peripheral interfaces. |
| IOFF partial power-down protection | Blocks current flow through powered-down device - essential for PCIe add-in cards, modular backplanes, and hot-pluggable I/O modules. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis - rejects noise on long traces or unterminated lines in motor control feedback or sensor signal conditioning. |
| JEDEC-compliant voltage ranges | Fully compliant with 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 legacy and modern logic families. |
Applications
| Industrial Bus Interface | Memory Address Latching |
|---|---|
Use Scenario: Isolating microcontroller GPIO banks from noisy 24 V industrial fieldbus transceivers (RS-485, CAN physical layer). IC Role / Device Role / Timing Role: Level-translating buffer with 5 V-tolerant inputs receiving differential receiver outputs; 3-state outputs drive local address/data bus. Use Value: Prevents latch-up during bus fault conditions while maintaining timing integrity (tpd ≤5.1 ns) for real-time control loop updates. | Use Scenario: Driving multiplexed address lines to parallel flash or SRAM in resource-constrained MCU designs. IC Role / Device Role / Timing Role: Octal non-inverting buffer amplifying weak MCU address pins; dual OE inputs allow bank-select gating synchronized with chip select. Use Value: Ensures clean edge transitions and sufficient drive strength (24 mA sink) to meet setup/hold timing margins across temperature extremes. |
| FPGA I/O Expansion | Hot-Swappable Module Interface |
Use Scenario: Extending limited FPGA I/O count to manage LED arrays, keypad scan lines, or sensor polling buses. IC Role / Device Role / Timing Role: Bidirectional-capable buffer (with external direction control) translating between 3.3 V FPGA core and 5 V peripheral logic. Use Value: Schmitt-trigger inputs suppress contact bounce noise from mechanical switches; 5 V tolerance avoids external clamping diodes. | Use Scenario: Interfacing pluggable daughterboards (e.g., analog front-end, radio module) to a main controller backplane. IC Role / Device Role / Timing Role: Isolation buffer with IOFF - outputs automatically enter high-Z when module is removed or unpowered, protecting host-side traces. Use Value: Eliminates risk of backfeed current damaging host controller during insertion/removal; certified for −40 °C to +125 °C operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC541APWR | TSSOP20 package (SOT360-1); identical electrical specs; 4.4 mm body width vs. 5.3 mm SSOP. | Better thermal resistance (10.0 mW/K derating above 100 °C) but lower creepage distance - unsuitable for reinforced isolation zones. | Select for space-constrained PCBs where thermal mass is less critical than footprint. |
| 74LVC244APW,118 | Dual 4-bit configuration (two independent OE controls); same VCC range and 5 V tolerance but no Schmitt inputs. | Lacks input hysteresis - requires clean, fast-rising signals; not recommended for noisy industrial sensor lines. | Choose only when separate control of two 4-bit channels is required and input signal integrity is guaranteed. |
Compared with SN74LVC541APWR and 74LVC244APW,118, the 74LVC541ADB,118 uniquely combines SSOP20 mechanical compatibility with Schmitt-trigger noise immunity and IOFF - making it optimal for ruggedized industrial modules requiring both signal integrity and safe hot-swap behavior.

FAQ
What is the maximum clock frequency supported by 74LVC541ADB,118?
The device has no internal clock; its usable data rate depends on propagation delay and system timing margins. With tpd ≤5.1 ns at VCC = 3.3 V, it supports reliable operation in address/data buses up to ~100 MHz assuming 5 ns setup/hold windows and controlled trace impedance. Actual max frequency is determined by board layout, load capacitance, and driver strength.
Can 74LVC541ADB,118 drive a 50 pF capacitive load at 3.3 V?
Yes - static and dynamic characteristics are specified with 50 pF loads (per Table 9 test conditions). At VCC = 3.3 V and IO = ±24 mA, VOL ≤0.55 V and VOH ≥2.2 V are guaranteed, and tpd remains ≤5.1 ns. For sustained 50 pF loading, ensure adequate PCB decoupling and avoid exceeding 500 mW total power dissipation.
Is 74LVC541ADB,118 qualified for automotive applications?
No - this part is not AEC-Q100 qualified. While it operates from −40 °C to +125 °C, Nexperia explicitly states in Section 14 that non-automotive qualified products lack automotive-specific stress testing, failure analysis, and process controls. Use only in industrial, computing, or consumer applications unless validated per customer automotive requirements.
How does IOFF functionality behave during power sequencing?
When VCC drops to 0 V, the IOFF circuit disables all outputs and limits OFF-state leakage to <±10 μA (per Table 6), preventing reverse current flow from live 5 V buses into the unpowered device. This protects upstream drivers and avoids unintended logic states during staggered power-up/down sequences in multi-rail systems.
