Product details
Overview
74HC541PW-Q100 from Nexperia is an automotive-grade octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 2.0 V to 6.0 V supply, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), with dual active-low output enables (OE1, OE2) and CMOS-level inputs - used for bidirectional data bus isolation and load driving in engine control units and body electronics.
For engineers reviewing the 74HC541PW-Q100 datasheet, 74HC541PW-Q100 pinout, 74HC541PW-Q100 application, or 74HC541PW-Q100 equivalent, key selection criteria include propagation delay (10–35 ns at VCC = 4.5–6.0 V), 3-state enable/disable timing (20–48 ns), output drive capability (±7.8 mA), input clamp diode support for overvoltage-tolerant interfacing, and automotive-qualified thermal and ESD robustness.
Technical Context
This device implements eight identical non-inverting buffer circuits, each with independent output control via two shared active-low enable inputs (OE1 and OE2). All outputs enter high-impedance state when either enable is HIGH, enabling flexible bus arbitration in multi-master systems.
Input clamp diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors; static characteristics guarantee VIH ≥ 3.15 V and VIL ≤ 1.35 V at VCC = 4.5 V, while dynamic performance maintains tpd ≤ 23 ns (typ) and tt ≤ 12 ns (typ) under CL = 50 pF loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V logic driving 5 V loads) |
| Propagation Delay (tpd) | 10 ns (typ) at VCC = 6.0 V - ensures sub-100 MHz bus timing margin in automotive serial control links |
| Output Drive Strength | ±7.8 mA at VCC = 4.5 V - sufficient to drive 50 pF loads across PCB traces without signal degradation |
| 3-State Enable Time (ten) | 20 ns (typ) at VCC = 4.5 V - enables fast bus turnaround in time-critical CAN or LIN subsystems |
| Input Clamp Current | ±20 mA - permits direct connection to 12 V sensor signals using external series resistors |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD immunity requirements per ISO 10605 |
| Operating Temperature | −40 °C to +125 °C - validated for under-hood deployment in powertrain and chassis modules |
Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-pin, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable inputs - both must be LOW for output drivers to be active; either HIGH forces all Yn into high-Z |
| 2–9 | A0–A7 | Data inputs - non-inverting, CMOS-compatible, with internal clamp diodes for overvoltage tolerance |
| 10 | GND | Ground reference - decoupling capacitor placement critical for noise immunity in automotive switching environments |
| 11–18 | Y0–Y7 | 3-state buffered outputs - capable of sourcing/sinking ±7.8 mA, with VOL ≤ 0.26 V and VOH ≥ 3.98 V at VCC = 4.5 V |
| 20 | VCC | Power supply - requires local 100 nF ceramic decoupling adjacent to pin to suppress transients from engine EMI |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full parametric testing - eliminates need for customer requalification in automotive ECUs |
| Dual independent output enables | OE1 and OE2 provide redundant or partitioned bus control - enables fault-isolated subsystem operation in ASIL-B designs |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using external current-limiting resistors - simplifies integration with 12 V sensors |
| Low dynamic power dissipation | CPD = 37 pF - limits switching current in high-frequency bus applications, reducing thermal load in sealed modules |
| High noise immunity | VIH/VIL margins exceed 30% of VCC across full temperature range - resists coupled noise from ignition systems and motors |
Applications
| Engine Control Unit (ECU) Data Bus Isolation | Body Control Module (BCM) Peripheral Driver |
|---|---|
Use Scenario: Isolating microcontroller GPIO banks from high-capacitance wiring harnesses during firmware updates. IC Role / Device Role / Timing Role: Non-inverting 3-state buffer providing bidirectional signal integrity and hot-swap-safe bus disconnection. Use Value: Enables zero-downtime reprogramming by placing outputs in high-Z during flash write cycles, preventing bus contention with other nodes. | Use Scenario: Driving LED status indicators and relay coils from low-drive MCU I/O pins in door modules. IC Role / Device Role / Timing Role: Octal line driver translating 3.3 V logic to 5 V/12 V compatible levels with current gain.

IC Role / Device Role / Timing Role: Low-skew octal buffer preserving signal integrity across 10+ cm PCB traces between sensor and SoC. Use Value: 12 ns typical transition time and 23 ns max propagation delay maintain pixel clock alignment across all 8 data lanes. | Use Scenario: PWM-controlled dimming of LCD backlight strings in head unit displays. IC Role / Device Role / Timing Role: 3-state gate driver enabling synchronized on/off control of multiple LED strings via shared enable lines. Use Value: Dual OE inputs allow coordinated fade-in/fade-out sequences across display zones without software overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT541PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging | Better suited for interfacing legacy 5 V TTL logic without level shifters | Select when mixing with older 74LS or 74F families; same footprint allows BOM flexibility |
| SN74LVC541APWR | Lower VCC range (1.65–3.6 V), higher speed (tpd = 5.2 ns typ), but not AEC-Q100 qualified | Limited to cabin infotainment or non-safety-critical modules | Choose only for cost-sensitive consumer-grade subsystems where automotive qualification is unnecessary |
Compared with 74HC541PW-Q100, the 74HCT541PW-Q100 offers seamless TTL interoperability without redesign, while the SN74LVC541APWR delivers faster timing at lower voltage but forfeits automotive reliability validation and thermal range.

FAQ
What is the maximum clock frequency supported by the 74HC541PW-Q100?
The 74HC541PW-Q100 is not a clocked device and has no defined clock frequency. Its usable data rate depends on propagation delay (≤35 ns max at VCC = 4.5 V) and load capacitance. For reliable operation with 50 pF loads, it supports data edges up to approximately 10 MHz without distortion, assuming proper termination and layout.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 and OE2 may be connected to a common control signal. The functional table confirms that a HIGH on either enable forces all outputs into high-impedance state. This configuration simplifies PCB routing and reduces MCU GPIO usage while preserving full 3-state functionality.
Does the 74HC541PW-Q100 support hot insertion or live bus connection?
No - the device lacks explicit hot-swap protection circuitry. While input clamp diodes tolerate brief overvoltage, applying VCC after signal inputs may cause latch-up or damage. Power sequencing must ensure VCC is stable before applying input signals, per JESD78 Class II Level B latch-up immunity rating.
How does the 74HC541PW-Q100 handle input signals above VCC?
Input pins include internal clamp diodes to VCC and GND. Signals up to VCC + 0.5 V are safe if current is limited to ±20 mA via external series resistors. For 12 V sensor interfacing, a 470 Ω resistor limits current to ~17 mA at VCC = 5 V, satisfying absolute maximum ratings without external diodes.
