Product details
Overview
74LV541APWJ from Nexperia is an octal non-inverting 3-state buffer/line driver with dual active-low output enables (OE1, OE2), operating from 2.0 V to 5.5 V supply, delivering ≤6 ns propagation delay at 5 V, and supporting mixed-voltage translation between 3.3 V and 5 V domains in industrial control backplanes.
For engineers reviewing the 74LV541APWJ datasheet, 74LV541APWJ pinout, 74LV541APWJ application, or 74LV541APWJ equivalent, key selection criteria include 3-state timing skew (<1 ns), IOFF-enabled partial power-down protection, Schmitt-trigger input tolerance for slow-edge signals, and TSSOP20 thermal derating above 100 °C.
Technical Context
This device implements eight independent non-inverting buffers, each with output enable control routed through two shared active-low OE inputs-OE1 controls Y0–Y3, OE2 controls Y4–Y7. All inputs feature Schmitt-trigger thresholds (VIH(AC) = 2.31 V, VIL(AC) = 0.99 V at VCC = 3.3 V), enabling robust noise immunity on asynchronous control lines.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ≤0.5 μA, and overvoltage-tolerant inputs accept up to 7.0 V regardless of VCC state-critical for hot-swap and level-shifting applications where supply sequencing is uncontrolled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.0 V to 5.5 V - supports single-rail operation across 2.5 V, 3.3 V, and 5 V logic families without external level shifters. |
| Max propagation delay | 6 ns at VCC = 5 V, CL = 15 pF - ensures sub-10 ns data path timing for high-speed parallel bus buffering. |
| IOFF leakage | ≤0.5 μA at VCC = 0 V - prevents damaging back-current during partial system power-down in modular PLC I/O modules. |
| Input overvoltage rating | −0.5 V to +7.0 V - allows safe interfacing with 5 V signals while powered from 3.3 V, eliminating need for external clamping diodes. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive body control modules and industrial motor drive control boards. |
| Output drive strength | ±35 mA per output - sufficient to directly drive 50 Ω transmission lines or fan-out to ≥10 LVTTL loads. |
| ESD protection | HBM >3000 V, CDM >2000 V - meets IEC 61000-4-2 Level 3 requirements for field-deployable equipment interfaces. |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm lead pitch, 1.1 mm max height - optimized for high-density PCB layouts with thermal pad omitted; JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable | Controls high-impedance state for Y0–Y3; asserted LOW enables outputs, HIGH disables them. |
| 2–9 (A0–A7) | Data inputs | Non-inverting inputs accepting overvoltage-tolerant signals; Schmitt-triggered for noise margin on slow-rising control buses. |
| 10 (GND) | Ground reference | Primary return path for all I/O and supply currents; must be low-inductance connection to minimize ground bounce. |
| 11–18 (Y0–Y7) | Data outputs | 3-state buffered outputs with IOFF protection; Y0–Y3 controlled by OE1, Y4–Y7 by OE2. |
| 19 (OE2) | Active-low output enable | Controls high-impedance state for Y4–Y7; independent of OE1 for split-bus isolation. |
| 20 (VCC) | Power supply | Single-supply rail supporting 2.0–5.5 V; decoupling capacitor required within 5 mm of pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-voltage translation | Inputs tolerate up to 7.0 V while VCC = 3.3 V - enables direct 5 V → 3.3 V signal bridging without external resistors or translators. |
| Partial power-down support | IOFF circuit limits output leakage to ≤0.5 μA when VCC = 0 V - prevents backfeed into powered subsystems during hot-swap events. |
| Slow-edge signal compatibility | Schmitt-trigger inputs with 1.32 V hysteresis at VCC = 3.3 V - rejects noise on long traces or mechanical switch inputs in factory automation panels. |
| High-speed 3-state control | Enable/disable times ≤10.5 ns at VCC = 5 V, CL = 50 pF - supports glitch-free bus arbitration in real-time motion control networks. |
| Industrial temperature grade | Specified from −40 °C to +125 °C - validated for continuous operation in sealed enclosures without forced air cooling. |
Applications
| Industrial PLC Backplane | Automotive Body Control Module |

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 | Lower max VCC (3.6 V), no overvoltage-tolerant inputs, IOFF not specified | Restricted to 3.3 V-only systems; unsuitable for mixed-voltage hot-swap scenarios | Select only if operating exclusively at 3.3 V with no supply sequencing risk and no need for 5 V signal tolerance. |
| 74LVC541AD | SO20 package (SOT163), higher thermal resistance (RθJA = 110 K/W vs. 100 K/W), same electrical specs | Less suitable for high-power-density PCBs requiring tight thermal management | Prefer for legacy SOIC footprints where board rework is prohibitive; avoid in thermally constrained industrial enclosures. |
Compared with SN74LVC541APWR and 74LVC541AD, the 74LV541APWJ uniquely combines 7.0 V input overvoltage tolerance, guaranteed IOFF behavior, and TSSOP20 thermal performance-making it the only option for robust mixed-voltage backplane buffering in harsh environments.

FAQ
Does 74LV541APWJ support true bidirectional data flow?
No. The 74LV541APWJ is a unidirectional octal buffer: signals flow only from A0–A7 inputs to Y0–Y7 outputs. It lacks internal direction control or bus transceiver architecture. For bidirectional applications like I²C or data bus multiplexing, a dedicated transceiver such as the 74LVC245 must be used instead.
Can OE1 and OE2 be tied together for single-enable operation?
Yes. OE1 and OE2 may be connected to a common control signal without electrical conflict, enabling all eight outputs simultaneously. This configuration maintains full 3-state functionality but forfeits independent control of the two 4-bit output groups-acceptable in simple bus drivers where split enable is unnecessary.
What is the maximum capacitive load this device can drive reliably?
The 74LV541APWJ is characterized up to 50 pF load capacitance in dynamic testing (tpd, ten, tdis), with typical output capacitance CO = 5 pF per buffer. Driving >50 pF risks exceeding specified timing margins and increasing ground bounce; for heavier loads, add series termination or use a dedicated line driver with higher drive strength.
Is the TSSOP20 package RoHS-compliant and lead-free?
Yes. The SOT360-1 (TSSOP20) package for 74LV541APWJ is fully RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-609 Category 3 marking requirements. Lead finish is matte tin, with peak reflow temperature rated to 260 °C per J-STD-020.
