Product details
Overview
NLV74HC541ADWR2G from onsemi is an octal 3-state noninverting buffer/line driver designed for bus-oriented systems including memory address drivers and clock distribution networks. It operates from 2.0 V to 6.0 V, delivers ±7.8 mA output drive at 6.0 V, features dual active-low output enables (OE1, OE2), and supports industrial temperature range (–55 °C to +125 °C) in SOIC-20 wide-body package.
For engineers reviewing the NLV74HC541ADWR2G datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin-level behavior, confirmed 3-state timing parameters (tPLZ/tPHZ ≤ 31 ns at 6.0 V), true supply voltage compatibility, and real-world interface use cases with TTL/CMOS buses.
Technical Context
The NLV74HC541ADWR2G implements eight independent noninverting buffers, each with high-impedance output control via two ANDed active-low enables. Its CMOS silicon-gate architecture ensures low input current (≤±1.0 µA) and high noise immunity across the full operating voltage range.
It is functionally identical to LS541 in pinout and supports direct interfacing to LSTTL loads (15 LSTTL loads per output), while requiring external pull-up resistors for LSTTL input compatibility. The device is not a level shifter - it does not translate between logic families unless externally biased.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Memory Address Buffering | Industrial Bus Isolation |
|---|---|
|
Use Scenario: Driving multiplexed address lines from a microcontroller to multiple SRAM or flash devices on a shared bus. IC Role / Device Role / Timing Role: Noninverting buffer with 3-state control isolates address lines during bus arbitration or chip select transitions. Use Value: Prevents address contention by enabling/disabling outputs synchronously via OE1/OE2, eliminating need for discrete gating logic. |
Use Scenario: Isolating sensor data lines from a PLC backplane to prevent ground loop interference and fault propagation. IC Role / Device Role / Timing Role: Bidirectional-capable line driver/receiver that decouples noisy field-side signals from clean controller-side logic. Use Value: High-impedance state blocks cross-talk during maintenance or module hot-swap, preserving system uptime. |
| Clock Distribution Network | Legacy System Interface |
|
Use Scenario: Fan-out of a single system clock to multiple peripheral ICs with matched trace lengths and minimal skew. IC Role / Device Role / Timing Role: Low-skew, noninverting buffer stage ensuring simultaneous clock edge delivery across 8 destinations. Use Value: Propagation delay variation ≤5 ns (tPLH–tPHL) maintains tight setup/hold margins for synchronous peripherals. |
Use Scenario: Interfacing modern 3.3 V or 5 V microcontrollers to legacy 5 V TTL peripherals (e.g., UART transceivers, display controllers). IC Role / Device Role / Timing Role: Level-compatible buffer that accepts CMOS or LSTTL inputs and drives LSTTL loads without external resistors. Use Value: Eliminates need for discrete level-shifting components while maintaining signal integrity over long PCB traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC541N | Same logic function and pinout; wider operating temp (–40 °C to +85 °C only); no AEC-Q100 qualification | Limited to commercial/industrial ambient environments; unsuitable for under-hood automotive use | Select when cost sensitivity outweighs extended temperature or automotive qualification needs |
| MC74HC541ADWG | Identical die and specs; differs only in packaging - SOIC-20 wide rail (38 units) vs. tape-and-reel (1000 units) | No functional difference; choice driven solely by procurement volume and assembly line requirements | Select for prototyping or low-volume hand-soldered builds where reel handling is unnecessary |
Compared with SN74HC541N and MC74HC541ADWG, the NLV74HC541ADWR2G uniquely combines AEC-Q100 qualification, –55 °C to +125 °C operation, and tape-and-reel packaging - making it the only option qualified for production automotive ECUs and high-reliability industrial controllers requiring automated placement.

FAQ
What is the exact logic function of the NLV74HC541ADWR2G?
The NLV74HC541ADWR2G is an octal 3-state noninverting buffer with dual active-low output enables (OE1 and OE2). When both enables are LOW, data on inputs A1–A8 passes unchanged to outputs Y1–Y8. If either OE1 or OE2 is HIGH, all Y outputs enter high-impedance state. This behavior is confirmed in the device's function table and logic diagram in the official onsemi datasheet.
Does the NLV74HC541ADWR2G support 3.3 V operation?
Yes, the NLV74HC541ADWR2G fully supports 3.3 V operation. Its guaranteed operating voltage range is 2.0 V to 6.0 V, and DC/AC specifications - including VOH ≥ 2.48 V and VOL ≤ 0.40 V at 3.0 V supply - are explicitly validated in the datasheet for VCC = 3.0 V conditions.
Is the NLV74HC541ADWR2G pin-compatible with standard LS541 devices?
Yes, the NLV74HC541ADWR2G is pin-compatible with the 74LS541. The datasheet states "identical in pinout to the LS541", and the pin assignment diagram confirms matching layout for all 20 pins - including A1–A8, Y1–Y8, OE1, OE2, VCC, and GND - enabling drop-in replacement in legacy designs.
What is the maximum output current capability of the NLV74HC541ADWR2G?
The NLV74HC541ADWR2G delivers up to ±7.8 mA per output at VCC = 6.0 V, as specified in the DC Characteristics table under IOH/IOL conditions. This allows direct driving of 15 LSTTL loads, and the value is measured with defined test conditions (|IOUT| ≤ 7.8 mA), not estimated or derived.
Does the NLV74HC541ADWR2G meet automotive qualification standards?
Yes, the NLV prefix denotes automotive-grade qualification. The NLV74HC541ADWR2G is AEC-Q100 qualified and PPAP capable, with operating temperature range extended to –55 °C to +125 °C and process controls aligned to automotive site and change requirements - as documented in the ordering information and marking diagrams section of the datasheet.
