Product details
Overview
74LV541PW,118 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 inputs (OE1, OE2), −40 °C to +125 °C temperature range, and TTL-level input compatibility at VCC ≥ 2.7 V - used for bidirectional bus interfacing in low-voltage industrial control backplanes.
For engineers reviewing the 74LV541PW,118 datasheet, 74LV541PW,118 pinout, 74LV541PW,118 application, or 74LV541PW,118 equivalent, key selection criteria include supply voltage flexibility (1.0–3.6 V), propagation delay ≤11 ns at 3.3 V, 3-state output leakage <10 µA, ESD robustness (>2000 V HBM), and compatibility with 74HC541/74HCT541 logic families.
Technical Context
The 74LV541PW,118 implements eight independent non-inverting buffer channels, each with high-impedance (Z) output control via two shared active-low enables (OE1 and OE2). Its Si-gate CMOS architecture ensures rail-to-rail output swing and low static current (ICC ≤ 20 µA typical at 3.6 V).
Functional behavior follows a strict truth table: outputs Y0–Y7 drive HIGH/LOW only when both OE1 and OE2 are LOW; any HIGH on either enable forces all outputs into high-impedance state. Input thresholds are TTL-compatible above 2.7 V supply and scaled CMOS-compatible down to 1.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tpd) | 11 ns max at VCC = 3.3 V, CL = 15 pF - enables reliable operation in 45 MHz bus systems with margin. |
| Output Enable Timing | Enable time (ten) ≤ 38 ns, disable time (tdis) ≤ 47 ns at VCC = 3.3 V - ensures clean bus turnaround in multiplexed data paths. |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V at VCC = 3.3 V - guarantees interoperability with standard TTL outputs. |
| OFF-State Leakage | IOZ ≤ 10 µA at VCC = 3.6 V - minimizes signal contention risk during bus arbitration. |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets industrial IEC 61000-4-2 system-level robustness requirements. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O stages. |
Pinout & Package
TSSOP20 package (SOT360-1): plastic thin shrink small outline, 20 leads, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not present, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable | Global control for first group of four outputs (Y0–Y3); LOW enables, HIGH disables. |
| 2–9 (A0–A7) | Data inputs | Non-inverting inputs driving corresponding Y0–Y7 outputs; accept TTL levels at VCC ≥ 2.7 V. |
| 10 (GND) | Ground reference | Primary 0 V return path for logic and output current; must be low-inductance connection. |
| 11–18 (Y0–Y7) | 3-state buffered outputs | Non-inverting outputs; enter high-impedance state when OE1 or OE2 is HIGH. |
| 19 (OE2) | Active-low output enable | Global control for second group of four outputs (Y4–Y7); paired with OE1 for full octal control. |
| 20 (VCC) | Positive supply | Single power rail (1.0–3.6 V); decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.0 V supply - enables integration into battery-powered and ultra-low-power sensor nodes. |
| Dual independent enables | OE1 and OE2 allow partitioned bus control - e.g., isolate memory vs. peripheral segments without extra logic. |
| High noise immunity | Typical ground bounce < 0.8 V at 3.3 V - reduces false triggering in dense PCB layouts with shared return paths. |
| Wide temperature qualification | Specified over −40 °C to +125 °C - suitable for engine control units and motor drive gate driver interfaces. |
| Pin/function compatibility | Drop-in replacement for 74HC541 and 74HCT541 - simplifies legacy design upgrades without layout changes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV541APWRE4 | TI version in same TSSOP20 package; VIH/VIL thresholds identical, but ICC max = 50 µA (vs. 70 µA for NXP) and tpd = 12.5 ns (vs. 11 ns). | Valid for cost-sensitive industrial designs where 1.5 ns timing margin is acceptable. | Select when TI supply chain preference or dual-sourcing strategy applies; verify layout compatibility with TI's thermal pad recommendation. |
| 74LVC541APW,118 | NXP LVC variant: wider VCC range (1.65–3.6 V), lower tpd (8.5 ns at 3.3 V), but no TTL input compatibility below 2.7 V. | Better for pure 3.3 V/2.5 V systems requiring faster switching; unsuitable for mixed 1.8 V/3.3 V TTL-interfaced buses. | Choose when maximum speed is critical and input voltage compatibility with legacy TTL is unnecessary. |
Compared with SN74LV541APWRE4, the 74LV541PW,118 offers tighter propagation delay and higher ICC limit tolerance; versus 74LVC541APW,118, it trades speed for broader voltage-range interoperability and TTL input support - making it optimal for brownfield upgrades and multi-rail bus bridging.

FAQ
What is the minimum supply voltage for reliable operation of the 74LV541PW,118?
74LV541PW,118 is guaranteed to function down to 1.0 V supply voltage, with static characteristics specified from 1.2 V. At 1.0 V, inputs must be driven to GND or VCC for correct logic interpretation - enabling use in ultra-low-power battery-backed subsystems where other logic families fail.
Does the 74LV541PW,118 support TTL-level inputs?
Yes, the 74LV541PW,118 accepts TTL input levels when VCC is between 2.7 V and 3.6 V, with VIH = 2.0 V and VIL = 0.8 V. This allows direct connection to legacy 5 V TTL outputs without external level shifters, simplifying migration paths in mixed-voltage systems.
How are the output enable inputs OE1 and OE2 used in the 74LV541PW,118?
In the 74LV541PW,118, both OE1 (pin 1) and OE2 (pin 19) are active-low enables. All eight outputs (Y0–Y7) go high-impedance if either OE1 or OE2 is HIGH. Only when both are LOW do outputs actively drive HIGH or LOW - enabling flexible bus partitioning or fault-isolation schemes.
What is the maximum propagation delay of the 74LV541PW,118 at 3.3 V supply?
The maximum propagation delay (tpd) of the 74LV541PW,118 is 11 ns at VCC = 3.3 V with CL = 15 pF, measured from input (An) to output (Yn). This value is specified across the full −40 °C to +125 °C operating range, ensuring timing predictability in thermally demanding environments.
Is the 74LV541PW,118 pin-compatible with 74HC541 devices?
Yes, the 74LV541PW,118 is pin and function compatible with 74HC541 and 74HCT541. The TSSOP20 footprint matches SO20 pinouts electrically and mechanically, allowing drop-in replacement in existing designs - provided supply voltage is adjusted to 1.0–3.6 V and timing margins are re-verified.
