Product details
Overview
74LVC541APW,118 from Nexperia is an octal 3-state buffer/line driver with dual output enables (OE1, OE2), 5 V-tolerant inputs/outputs, 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. It is used in bus interfacing, level-shifting, and data routing in industrial control backplanes.
For engineers reviewing the 74LVC541APW,118 datasheet, 74LVC541APW,118 pinout, 74LVC541APW,118 application, or 74LVC541APW,118 equivalent, key selection criteria include 5 V input tolerance, dual 3-state enable control, IOFF leakage suppression during power-down, and TSSOP20 packaging for high-density PCB layouts.
Technical Context
The device implements eight independent non-inverting buffers, each with bidirectional voltage translation capability enabled by overvoltage-tolerant input structures. Its dual active-low output enables allow selective tri-stating of two groups of outputs, supporting flexible bus arbitration schemes.
Schmitt-trigger inputs provide hysteresis (≥0.3 V typical) to reject slow-rising/falling signals and reduce susceptibility to ground bounce or EMI. The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ≤±20 μA at 5.5 V applied to I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic while maintaining 5 V input tolerance. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - Allows safe connection to 5 V sources without level shifters in mixed-supply systems. |
| Propagation Delay (VCC = 3.3 V) | 1.0 ns to 5.1 ns - Supports >100 MHz data rates in high-speed digital buses with predictable timing margins. |
| IOFF Leakage Current | ≤±20 μA at VCC = 0 V - Prevents damaging back-current flow during hot-swap or partial power-down sequences. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in manufacturing and field service. |
| 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
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE1 | Active-low output enable for Y0–Y7 group - Asserting LOW enables all eight outputs simultaneously. |
| 2 | VCC | Main supply rail - Powers internal logic and output drivers; decoupling required within 10 mm. |
| 3–10 | A0–A7 | Buffer input terminals - Accept 5 V-tolerant signals; Schmitt-triggered for noise margin ≥0.3 V. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - Drive loads up to 24 mA HIGH/LOW; enter high-Z when either OE1 or OE2 is HIGH. |
| 19 | OE2 | Active-low output enable for same Y0–Y7 group - Dual-enable architecture allows redundant or split control paths. |
| 20 | GND | Reference ground - Must be low-impedance; shared with VCC decoupling capacitor return path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 3-state output enables | Independent OE1/OE2 pins allow synchronized or staggered bus release, reducing contention glitches in multi-driver systems. |
| 5 V tolerant I/O with 1.2 V–3.6 V VCC | Eliminates external level shifters when interfacing legacy 5 V peripherals to modern low-voltage microcontrollers. |
| IOFF partial power-down protection | Blocks >99% of back-current flow when VCC is removed, enabling safe live insertion into powered backplanes. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis to suppress noise on slow edges, enabling reliable operation with RC-filtered or long-trace signals. |
| JEDEC-compliant voltage ranges | Fully supports JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) for interoperability across 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) | Identical pinout and DC specs; slightly higher typical tpd (6.5 ns vs. 5.1 ns at 3.3 V); no IOFF spec in datasheet. | Lacks documented IOFF behavior - unsuitable for hot-swap or partial power-down use cases requiring back-current blocking. | Select only if IOFF is not required and TI supply chain preference applies. |
| 74LVCH162244ADGG,118 (Nexperia) | 16-bit, dual-supply (1.2–3.6 V core / 1.2–5.5 V I/O), but requires separate VCCA/VCCB rails and has larger TSSOP48 package. | Supports true dual-voltage operation but increases layout complexity and power sequencing requirements. | Choose only when 16-bit width and independent I/O voltage control justify added design overhead. |
Compared with SN74LVC541APWR, the 74LVC541APW,118 offers verified IOFF protection critical for power-aware systems; compared with 74LVCH162244ADGG,118, it delivers identical functionality in half the footprint and without dual-rail complexity.

FAQ
Can 74LVC541APW,118 drive 5 V TTL loads directly?
Yes - its outputs are 5 V-tolerant and can source/sink up to 24 mA while maintaining VOH ≥2.2 V and VOL ≤0.55 V at VCC = 3.0 V, meeting TTL input thresholds (VIH ≥2.0 V, VIL ≤0.8 V). No external pull-ups or level shifters are needed.
What happens to outputs when VCC is 0 V and 5 V is applied to inputs or outputs?
The IOFF circuit activates automatically, limiting output leakage current to ≤±20 μA even with 5.5 V applied to any I/O pin. This prevents destructive back-current flow into the unpowered VCC rail, satisfying IEC 61000-4-2 system-level ESD robustness requirements.
Is the TSSOP20 package (SOT360-1) lead-free and RoHS compliant?
Yes - the 74LVC541APW,118 uses a lead-free, halogen-free, RoHS-compliant matte tin finish on copper leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85% RH.
How does Schmitt-trigger input action improve noise immunity?
Schmitt-trigger inputs provide ≥0.3 V hysteresis between VIH and VIL thresholds, rejecting transient noise spikes and slow-rising signals (e.g., from long cables or RC networks) that would cause multiple toggles on standard CMOS inputs, thereby eliminating false triggering in noisy industrial environments.
