Product details
Overview
74LV541PW,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 1.0 V to 3.6 V supply, with dual active-low output enable (OE1/OE2), −40 °C to +125 °C temperature range, and pin/function compatibility with 74HC541/74HCT541. It serves as a level-translating bus interface in low-voltage digital systems such as industrial control backplanes and embedded microcontroller I/O expansion.
For engineers reviewing the 74LV541PW,112 datasheet, 74LV541PW,112 pinout, 74LV541PW,112 application, or 74LV541PW,112 equivalent, key selection considerations include its 3.3 V–compatible TTL input thresholds, 10 ns typical propagation delay at VCC = 3.3 V, 8 mA output drive capability, high-impedance OFF-state leakage < 10 µA, and ESD robustness (HBM > 2000 V).
Technical Context
The 74LV541PW,112 implements eight independent non-inverting buffer channels, each with controlled 3-state output enabled by two shared active-low OE inputs. Its Si-gate CMOS architecture ensures rail-to-rail output swing and low static current (ICC < 160 µA at VCC = 3.6 V).
It supports mixed-voltage interfacing: accepts TTL-level inputs when VCC ≥ 2.7 V, maintains logic integrity across −40 °C to +125 °C, and features ground bounce < 0.8 V and VOH undershoot > 2 V at VCC = 3.3 V - critical for noise-sensitive data bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tpd) | 10 ns typical at VCC = 3.3 V, CL = 15 pF - supports >30 MHz bus operation in synchronous systems. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or fan-out to 10+ LS-TTL loads. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V at VCC = 2.7–3.6 V - ensures reliable recognition of standard TTL input levels. |
| OFF-State Leakage | IOZ ≤ 10 µA at VCC = 3.6 V - minimizes bus contention current during tri-state arbitration. |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets industrial handling requirements without external protection. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC environments. |
Pinout & Package
74LV541PW,112 uses the SOT360-1 (TSSOP20) package: 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm lead pitch, and exposed pad not present. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable inputs - both must be LOW to activate all eight outputs; independent control allows partial bus gating. |
| 2–9 | A0–A7 | Non-inverting data inputs - directly connected to upstream logic; no internal pull-ups or pull-downs. |
| 10 | GND | Ground reference - must be low-inductance connection to minimize switching noise coupling. |
| 11–18 | Y0–Y7 | Buffered non-inverting outputs - present high-impedance (Z) state when either OE is HIGH. |
| 20 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.0 V supply - supports ultra-low-power battery-backed subsystems and energy harvesting interfaces. |
| TTL-input compatibility | Valid VIH/VIL thresholds at VCC ≥ 2.7 V - eliminates need for external translators when interfacing legacy 5 V peripherals. |
| Controlled output transition | Typical ground bounce < 0.8 V at VCC = 3.3 V - reduces simultaneous switching noise on shared power rails. |
| High-temperature rating | Full functionality up to +125 °C - suitable for engine control units and power converter gate driver support circuits. |
| Small footprint | TSSOP20 (4.4 mm × 6.5 mm) - saves PCB area vs. SO20 or DIP20 while maintaining hand-solderability. |
Applications
| Industrial Backplane Interface | Microcontroller I/O Expansion |

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 |
|---|---|---|---|
| 74LVC541APW,118 | Lower ICC (max 10 µA at VCC = 3.3 V), same TSSOP20 package, but only rated to +85 °C. | Suitable for commercial-grade consumer electronics where extended temperature is not required. | Select when ultra-low static power dominates over industrial temperature range. |
| SN74LV541APWR | Identical electrical specs and pinout, but TI-manufactured with different thermal resistance (RθJA = 110 K/W vs. NXP's 125 K/W) and RoHS-6 compliance only. | Acceptable for drop-in replacement in existing designs if sourcing diversification is needed. | Choose when supply chain redundancy is prioritized and thermal margin >15 K is available. |
Compared with 74LV541PW,112, the 74LVC541APW,118 trades extended temperature capability for lower quiescent current, while the SN74LV541APWR offers identical functional behavior with minor thermal and compliance differences - making the original NXP part optimal for high-reliability industrial and automotive use cases requiring full −40 °C to +125 °C validation.

FAQ
What is the maximum recommended supply voltage for 74LV541PW,112?
The absolute maximum supply voltage (VCC) for 74LV541PW,112 is +4.6 V, but the recommended operating range is strictly 1.0 V to 3.6 V. Operation above 3.6 V risks permanent damage and violates the device's characterization - sustained use at 4.6 V is not supported and voids reliability guarantees.
Does 74LV541PW,112 support true bidirectional data flow?
No, 74LV541PW,112 is a unidirectional non-inverting buffer: signals flow only from A0–A7 inputs to Y0–Y7 outputs. It lacks internal direction control or bus transceiver logic. For bidirectional applications, discrete directional control logic or a dedicated transceiver like 74LV245 must be used alongside 74LV541PW,112.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 and OE2 are electrically independent but functionally identical active-low enables. They may be wired in parallel to a single control signal without adverse effects, simplifying PCB layout and reducing GPIO usage. This configuration maintains full 3-state control over all eight outputs.
What is the output capacitance loading limit for stable 74LV541PW,112 operation?
The 74LV541PW,112 is characterized with CL = 15 pF and 50 pF loads. While it can drive higher capacitances, propagation delay increases linearly beyond 50 pF, and ringing or overshoot may occur above ~75 pF without series termination. For >50 pF loads, add a 22–33 Ω series resistor near the driver output.
Is 74LV541PW,112 pin-compatible with 74HC541 in TSSOP20 package?
No - 74HC541 is not offered in TSSOP20 by NXP or major manufacturers. The 74LV541PW,112 is pin- and function-compatible with 74HC541 *logic*, but physical compatibility requires matching package: 74HC541 is typically available in SO20 or DIP20 only. Direct PCB substitution is not possible without footprint redesign.
