Product details
Overview
74ALVC541BQ,115 from Nexperia is an octal non-inverting 3-state buffer/line driver with dual active-low output enables (OE0, OE1), Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It operates from 1.65 V to 3.6 V, supports -40 °C to +125 °C ambient, and delivers propagation delay as low as 2.3 ns at 3.3 V - used in bus interface isolation, level translation between mixed-voltage logic domains, and high-speed data routing in industrial controllers.
For engineers reviewing the 74ALVC541BQ,115 datasheet, 74ALVC541BQ,115 pinout, 74ALVC541BQ,115 application, or 74ALVC541BQ,115 equivalent, key selection criteria include dual-OE control timing, IOFF-enabled hot-swap compatibility, Schmitt-trigger input hysteresis (≥0.3 V typical), and DHVQFN20 thermal performance for dense PCB layouts.
Technical Context
This device implements eight independent non-inverting buffers, each with separate output enable control via OE0 (pins 1, 19) and OE1 (pin 19, shared). All inputs feature Schmitt-trigger action with hysteresis ≥0.3 V, enabling robust operation with slow-rising signals and noisy environments. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA.
It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.5 V), and JESD8C/JESD36 (2.7–3.6 V), and meets HBM ESD >2000 V and CDM >1000 V. Functional behavior is defined by a three-state truth table where either OE0 or OE1 LOW enables corresponding Yn outputs; both HIGH forces all outputs into high-impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 3.6 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V logic families without level shifters. |
| Propagation delay (An→Yn) | 2.3 ns typical at VCC = 3.3 V - supports >200 MHz data rates in point-to-point bus applications. |
| IOFF leakage | ±10 μA max at VCC = 0 V - prevents damaging back-current during live insertion or partial system power-down. |
| Input hysteresis | ≥0.3 V typical - rejects noise on slow edges (e.g., mechanical switch debouncing or long trace signals). |
| Output drive strength | ±24 mA at VCC = 3.0 V - drives 50 pF loads with <3.5 ns transition while maintaining VOL ≤ 0.55 V and VOH ≥ 2.2 V. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-temperature embedded systems. |
| ESD rating | HBM >2000 V, CDM >1000 V - exceeds IEC 61000-4-2 Level 3 for board-level robustness. |
Pinout & Package
DHVQFN20 package (SOT764-1): 2.5 × 4.5 × 0.85 mm body, 20-terminal no-lead quad flat design with exposed thermal pad (non-soldered or floating GND connection per datasheet note). Optimized for thermal dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE0 / OE1 | Dual active-low output enables - OE0 controls Y0–Y7 odd/even grouping per functional diagram; OE1 shares pin 19 for synchronized disable. |
| 2–9 | A0–A7 | Buffer input terminals - Schmitt-triggered for noise margin; tolerant of 0–3.6 V inputs regardless of VCC. |
| 11–18 | Y0–Y7 | Non-inverting 3-state outputs - high-drive, rail-to-rail compatible, with IOFF protection when powered down. |
| 10, 20 | GND / VCC | Power reference and supply - decoupling required within 3 mm; thermal pad improves θJA by ~15 °C/W vs. TSSOP. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–3.6 V) | Eliminates need for external voltage translators in mixed-supply systems like FPGA I/O banks interfacing with microcontrollers. |
| IOFF partial power-down | Enables hot-plug capability in modular backplanes by preventing current backflow when one board powers off while others remain active. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis to reliably digitize slow analog-like signals (e.g., reset lines, sensor thresholds) without external RC filtering. |
| High ESD robustness | HBM >2000 V and CDM >1000 V reduce field failure risk in manufacturing handling and end-user environments with static-prone enclosures. |
| Thermally enhanced DHVQFN | SOT764-1 package achieves 12.9 mW/K derating above 111 °C - supports sustained 500 mW total power dissipation in compact motor-control PCBs. |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module (Non-Automotive Qualified) |

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 | Single OE pin (OE), no Schmitt inputs, identical VCC range and drive strength. | Lacks noise immunity on slow edges; requires external filtering for mechanical switch inputs. | Select when cost sensitivity outweighs noise immunity needs and only one global enable is required. |
| 74LVC541ADB | TSSOP20 package (SOT360-1), same logic function and specs but higher θJA (10.0 mW/K derating above 100 °C). | Lower thermal performance limits sustained high-speed operation in sealed enclosures. | Prefer for legacy PCB footprints matching SO20/TSSOP; avoid in thermally constrained 125 °C designs. |
Compared with SN74LVC541APWR and 74LVC541ADB, the 74ALVC541BQ,115 uniquely combines dual OE control, Schmitt-trigger inputs, and DHVQFN20 thermal efficiency - making it optimal for noise-prone, hot-swap, and space-limited industrial interfaces where signal integrity and power sequencing matter.

FAQ
Can 74ALVC541BQ,115 be used with 5 V logic inputs?
No - inputs are overvoltage tolerant to 3.6 V maximum, not 5 V. Applying 5 V violates absolute maximum ratings and risks permanent damage. Use a level translator such as TXS0108E if interfacing with 5 V systems.
What is the function of the exposed thermal pad on the DHVQFN20 package?
The thermal pad (terminal 1 index area) has no electrical function per datasheet note (1); it may be left floating or connected to GND. Soldering it improves thermal resistance by ~15 °C/W but introduces no signal or power path - it serves purely for heat dissipation.
How does IOFF protect during partial power-down?
When VCC = 0 V, the IOFF circuit disables all outputs and blocks current flow between Yn pins and internal circuitry. This prevents backflow currents up to ±50 mA that could damage upstream drivers or cause latch-up in powered sections of the system.
Is 74ALVC541BQ,115 qualified for automotive applications?
No - this part is not AEC-Q100 qualified and is explicitly designated for industrial and commercial use. Nexperia's datasheet states "non-automotive qualified products" require customer indemnification if used in automotive contexts; no automotive stress testing or qualification data is provided.
