Product details
Overview
74ALVC541PW,112 from Nexperia is an octal non-inverting 3-state buffer/line driver with dual active-low output enables (OE0 and 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 in high-speed digital bus interfacing applications.
For engineers reviewing the 74ALVC541PW,112 datasheet, 74ALVC541PW,112 pinout, 74ALVC541PW,112 application, or 74ALVC541PW,112 equivalent, this device is selected for level translation between mixed-voltage logic domains, bidirectional bus isolation in industrial controllers, and robust signal conditioning in noisy embedded I/O subsystems.
Technical Context
This CMOS device implements eight independent non-inverting buffers, each with separate input-to-output path and shared dual enable control. Its Schmitt-trigger inputs accept slow-rising signals down to 10 ns/V transition rate and tolerate overvoltage up to 3.6 V regardless of VCC.
The IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, blocking backflow current during hot-insertion or partial system power-down. Input leakage remains ≤ ±0.1 μA across full temperature range, enabling reliable operation in low-power standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 3.6 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V logic families without level shifters |
| Propagation delay (tpd) | 2.3 ns typical at VCC = 3.3 V - enables >200 MHz bus operation with margin for trace routing |
| Output drive strength | ±24 mA at VCC = 3.0 V - drives 50 pF loads with <3.5 ns rise/fall while maintaining VOL ≤ 0.3 V and VOH ≥ 2.2 V |
| IOFF leakage | ±0.1 μA max at VCC = 0 V - prevents cross-current damage during live insertion or multi-rail sequencing |
| Input hysteresis | ≈0.3 V at VCC = 3.3 V - rejects noise spikes up to 300 mV on slow-switching control lines |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC backplanes |
| ESD rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE0) | Active-low output enable | Disables Y0–Y3 when LOW; enables when HIGH - provides granular control over first half of buffer bank |
| 2 (VCC) | Positive supply | Power rail for all internal logic and output drivers; must be decoupled within 5 mm of pin |
| 3–10 (A0–A7) | Data inputs | Eight Schmitt-trigger buffered inputs accepting TTL/CMOS levels; tolerant of slow edges and overvoltage |
| 11–18 (Y0–Y7) | Data outputs | Eight 3-state CMOS outputs; high-impedance when either OE0 or OE1 is HIGH |
| 19 (OE1) | Active-low output enable | Disables Y4–Y7 when LOW; enables when HIGH - enables independent control of second buffer group |
| 20 (GND) | Ground reference | 0 V return for all internal circuits and output load paths; requires low-inductance connection |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | OE0 controls Y0–Y3; OE1 controls Y4–Y7 - allows interleaved bus access or split-bank isolation in memory-mapped peripherals |
| IOFF partial power-down | Outputs disable automatically when VCC = 0 V - eliminates need for external isolation switches during firmware updates or sleep mode entry |
| Schmitt-trigger inputs | Hysteresis ≈15 % of VCC - enables reliable sampling of mechanical switch bounce or long PCB traces without external RC filtering |
| Overvoltage-tolerant inputs | Accepts VI up to 3.6 V independent of VCC - permits safe connection to 3.3 V buses even when powered from 1.8 V rails |
| JEDEC-compliant voltage ranges | Valid across JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.5 V), and JESD8C/JESD36 (2.7–3.6 V) - ensures interoperability across legacy and modern logic families |

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 | TI part with identical pinout and function but higher ICC (max 10 μA vs 80 μA) and tighter VOH/VOL specs at 3.3 V | Better suited for battery-powered portable instruments requiring ultra-low static current | Select if supply current <1 μA at VCC = 3.3 V is mandatory; verify OE polarity compatibility (both active-low) |
| 74LVC541AD,118 | Nexperia SO20 variant (SOT163-1); same electrical specs but larger footprint and lower thermal resistance (12.3 mW/K derating) | Preferred for high-reliability industrial boards where TSSOP rework risk or thermal cycling fatigue is a concern | Select when manual assembly, wave soldering, or long-term thermal cycling reliability outweighs space constraints |
Compared with SN74LVC541APWR, 74ALVC541PW,112 offers superior noise immunity via wider Schmitt hysteresis and better overvoltage tolerance; compared with 74LVC541AD,118, it saves 40 % PCB area but requires stricter reflow profile control due to finer pitch.

FAQ
Can 74ALVC541PW,112 operate with VCC = 1.65 V while driving 50 pF loads at 10 MHz?
Yes. At VCC = 1.65 V, the device guarantees tpd ≤ 4.6 ns and VOL ≤ 0.3 × VCC (0.495 V) with 6 mA sink current, sufficient for 10 MHz square-wave signaling into 50 pF. Static current remains ≤10 μA, preserving low-power operation.
What is the maximum allowable input voltage when VCC = 0 V?
The absolute maximum input voltage is -0.5 V to +4.6 V per Table 4, regardless of VCC state. With VCC = 0 V, inputs may safely remain at up to 3.6 V due to overvoltage-tolerant design - critical for hot-swap scenarios where upstream logic remains powered.
How does the IOFF feature behave during power sequencing where VCC ramps after GND?
IOFF activates when VCC drops below ~0.8 V, forcing outputs into high-impedance before VCC reaches 0 V. During ramp-up, outputs remain disabled until VCC exceeds 1.0 V, preventing transient glitches - verified per JESD78 Class II.A latch-up testing.
Is the thermal pad on SOT360-1 (TSSOP20) electrically connected to GND?
No. The exposed thermal pad has no electrical connection per datasheet note: "This is not a ground pin. There is no electrical or mechanical requirement to solder the pad." If soldered, it must remain floating or tied to GND - no internal bond exists.
