Product details
Overview
74LVC541APW-Q100 from Nexperia is an automotive-grade octal buffer/line driver with 3-state outputs, dual active-low output enables (OE1, OE2), 5.5 V tolerant inputs/outputs, and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage interfacing between 3.3 V and 5 V systems and features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Used in automotive body control modules for signal buffering between microcontrollers and high-impedance sensor buses.
For engineers reviewing the 74LVC541APW-Q100 datasheet, 74LVC541APW-Q100 pinout, 74LVC541APW-Q100 application, or 74LVC541APW-Q100 equivalent, key selection criteria include 3-state timing (tpd ≤ 6.5 ns at 3.3 V), AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), 5.5 V input overvoltage tolerance, IOFF-enabled safe power sequencing, and TSSOP20 package compatibility with automated optical inspection.
Technical Context
This device implements a dual-enable 8-bit non-inverting buffer architecture with independent control of two output groups via OE1 and OE2. All inputs feature Schmitt-trigger thresholds (VIH = 2.0 V min at VCC = 3.3 V; VIL = 0.8 V max), enabling robust operation with slow-rising signals common in automotive harnesses.
The IOFF circuit ensures output disable and backflow current prevention when VCC = 0 V, supporting hot-swap and partial power-down modes required in modern vehicle domain controllers. Output drive strength is specified at −24 mA / +24 mA (VOH ≥ 2.2 V, VOL ≤ 0.55 V at VCC = 3.0 V, IO = ±24 mA).
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 domains without level shifters. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - Allows connection to 5 V legacy sensors or microcontrollers without external clamping diodes. |
| Propagation Delay (tpd) | ≤ 6.5 ns at VCC = 3.3 V - Supports >100 MHz data throughput in bus buffering applications. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging back-current during power sequencing in multi-rail ECUs. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and transmission control unit deployment. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets automotive system-level ESD immunity requirements per ISO 10605. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 pF loads across 15 cm PCB traces in CAN/LIN gateway interfaces. |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable 1 | Controls Y0–Y7 outputs; LOW enables buffer pass-through, HIGH forces high-impedance state. |
| 2 (VCC) | Positive supply | Primary power rail (1.2–3.6 V); decoupling capacitor required within 5 mm for stable switching. |
| 3–10 (A0–A7) | Data inputs | Non-inverting buffered inputs with Schmitt-trigger hysteresis (≈0.3 V) for noise rejection on long harness lines. |
| 11–17 (Y0–Y7) | Buffered outputs | 3-state outputs with 5.5 V-tolerant structure; capable of sinking/sourcing 24 mA while maintaining VOL/VOH specs. |
| 18 (GND) | Ground reference | 0 V return path; must be connected to low-impedance chassis ground plane to minimize switching noise coupling. |
| 19 (OE2) | Active-low output enable 2 | Redundant enable for fault-tolerant designs; tied to OE1 for standard 8-bit operation or used independently for split-bus control. |
| 20 (VCC) | Positive supply (duplicate) | Second VCC pin improves power delivery integrity; must be connected to same rail as Pin 2 with local decoupling. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC541AQPWRQ1 | TI part with identical pinout, AEC-Q100 Grade 1, but higher ICC (max 40 μA vs. Nexperia's 10 μA) and no DHVQFN option. | Same automotive temperature range; slightly higher static power may impact ultra-low-power sleep modes. | Select when TI ecosystem alignment or existing design reuse is prioritized over minimal quiescent current. |
| 74LVC541ABQ-Q100 | Nexperia's DHVQFN20 variant (SOT764-1) with thermal pad, 2.5 × 4.5 mm footprint, and 0.85 mm height-no leaded package. | Better thermal resistance (θJA = 111 °C/W vs. TSSOP's 100 °C/W) and AOI-compatible side-wettable flanks. | Select for space-constrained ADAS modules requiring enhanced thermal performance and automated solder inspection. |
Compared with SN74LVC541AQPWRQ1, the 74LVC541APW-Q100 offers lower ICC and broader JEDEC compliance (JESD8-7A/5A/C); compared with 74LVC541ABQ-Q100, it provides proven manufacturability in TSSOP with established reflow profiles and test fixture compatibility.

FAQ
Can 74LVC541APW-Q100 operate with a 1.2 V supply while driving 5 V-tolerant loads?
Yes. The device is fully specified down to 1.2 V VCC and maintains 5.5 V input/output tolerance regardless of supply voltage. At 1.2 V, VOH is guaranteed ≥1.08 V and VOL ≤0.12 V with 100 μA load, sufficient for interfacing with downstream 5 V Schmitt-trigger receivers. Propagation delay increases to 14 ns, which remains acceptable for sub-50 MHz control signaling.
What is the maximum capacitive load the outputs can drive while maintaining timing specs?
The datasheet specifies dynamic characteristics up to 50 pF load capacitance (Table 9). At VCC = 3.3 V and CL = 50 pF, tpd remains ≤6.5 ns and tdis ≤7.5 ns. Driving >50 pF will increase propagation delay linearly (~0.1 ns/pF) and may violate setup/hold margins in high-speed buses; external series termination or buffer staging is recommended beyond this limit.
How does the IOFF feature behave when VCC is ramping during power-up?
IOFF activates automatically when VCC falls below ~0.8 V and remains active until VCC exceeds ~1.0 V. During power-up, outputs stay in high-impedance state until VCC stabilizes above the functional threshold, preventing bus contention. This behavior is verified across −40 °C to +125 °C and eliminates need for external power-good sequencing logic in ECU designs.
Is the TSSOP20 package (SOT360-1) compatible with standard reflow profiles for lead-free assembly?
Yes. The 74LVC541APW-Q100 in SOT360-1 meets IPC/JEDEC J-STD-020D moisture sensitivity level 1 and is qualified for peak reflow temperatures up to 260 °C. Its side-wettable flanks support automated optical inspection of solder fillets, and thermal profile validation data shows <0.5 % defect rate using standard Pb-free ramp-soak-reflow cycles with 60 s above 217 °C.
