Product details
Overview
74HC541D-Q100 from Nexperia is an automotive-qualified octal non-inverting 3-state buffer/line driver in SO20 (SOT163-1) package, operating from 2.0 V to 6.0 V supply, delivering 7.8 mA output drive at 4.5 V, with propagation delay as low as 10 ns at VCC = 6.0 V and CL = 50 pF, used for bidirectional bus interfacing in engine control units and body electronics.
For engineers reviewing the 74HC541D-Q100 datasheet, 74HC541D-Q100 pinout, 74HC541D-Q100 application, or 74HC541D-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), dual active-low output enables (OE1/OE2), CMOS input thresholds, and SO20 thermal derating profile above 109 °C.
Technical Context
This device implements eight identical non-inverting buffer circuits with independent 3-state control via two active-low enable inputs (OE1, OE2), allowing partial bus isolation. Each output transitions between full-drive and high-impedance states without internal contention.
Input clamp diodes support interface to voltages exceeding VCC when used with current-limiting resistors. Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with VIH/VIL thresholds scaled to VCC for 74HC logic family compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and brown-out resilience down to 2.0 V logic operation. |
| Output drive strength | ±7.8 mA at VCC = 4.5 V - sufficient to drive 50 pF loads with <35 ns propagation delay and <18 ns disable time. |
| Propagation delay (An→Yn) | 10 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in 20+ MHz digital control buses. |
| Operating temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
| Input threshold type | CMOS-level - VIH = 3.15 V (min) at VCC = 4.5 V, ensuring noise margin >1.3 V in 5 V systems. |
| ESD protection | HBM >2000 V, CDM >1000 V - meets automotive board-level ESD robustness requirements without external protection. |
| Power dissipation capacitance | 37 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design. |
Pinout & Package
74HC541D-Q100 uses the SO20 plastic small outline package (SOT163-1), 7.5 mm body width, 20-pin surface-mount format with standard 1.27 mm pitch. Thermal resistance θJA = 80 K/W (JEDEC Std. 51-2); total power dissipation derates linearly at 12.3 mW/K above 109 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable inputs - both must be LOW to activate all eight outputs; either HIGH forces all Yn into high-Z state. |
| 2–9 | A0–A7 | Non-inverting data inputs - directly connected to internal buffer inputs; CMOS-compatible voltage thresholds. |
| 10 | GND | Ground reference - return path for all I/O and supply currents; requires low-impedance PCB connection. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - non-inverting copies of A0–A7 when OE1=OE2=LOW; high-impedance otherwise. |
| 20 | VCC | Positive supply - powers all internal logic and output drivers; decoupling capacitor (100 nF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | OE1 and OE2 allow selective activation of subsets of outputs or redundant enable paths for fault-tolerant designs. |
| Input clamp diodes | Enable safe interface to signals up to VCC + 0.5 V using external current-limiting resistors - eliminates need for level-shifters in overvoltage scenarios. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events in automotive environments. |
| Wide VCC range | 2.0 V to 6.0 V operation supports legacy 5 V, modern 3.3 V, and battery-backed 2.5 V subsystems without redesign. |
| High noise immunity | Typical noise margin >1.3 V at 4.5 V supply - rejects coupled transients on shared PCB traces in noisy engine compartments. |
Applications
| Engine Control Unit (ECU) Data Bus Isolation | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Isolating microcontroller GPIO banks from high-capacitance sensor/actuator buses during sleep mode. IC Role / Device Role / Timing Role: Non-inverting 3-state buffer enabling/disabling signal paths between MCU and LIN/CAN peripheral interfaces. Use Value: Reduces standby current by forcing Yn into high-Z, eliminating leakage through unpowered peripherals while maintaining signal integrity during wake-up transitions. |
Use Scenario: Driving multiple LED indicators and relay coils from a single 3.3 V microcontroller I/O port. IC Role / Device Role / Timing Role: Octal line driver boosting logic-level outputs to 5 V/7.8 mA capable of sinking relay coil current and lighting LEDs directly. Use Value: Eliminates need for discrete transistor arrays; SO20 footprint allows dense layout in space-constrained BCM PCBs. |
| Instrument Cluster Display Interface | ADAS Camera Power Sequencing |
|
Use Scenario: Level-shifting and buffering parallel RGB data lines between 3.3 V display controller and 5 V TFT panel timing IC. IC Role / Device Role / Timing Role: CMOS-input, non-inverting buffer providing clean edge transitions and drive strength for 50 pF pixel clock and data lines. Use Value: Ensures <35 ns propagation delay margin for 25 MHz pixel clocks; AEC-Q100 qualification guarantees reliability over 15-year instrument cluster lifetime. |
Use Scenario: Controlling power-enable sequencing for multi-rail camera modules (MIPI CSI-2, analog sensor, lens actuator). IC Role / Device Role / Timing Role: Octal buffer with dual OE inputs synchronizing enable signals to meet strict power-up/down timing windows (<100 μs) defined in camera datasheets. Use Value: Dual OE pins allow staggered activation (e.g., OE1 for analog rail, OE2 for digital rail), preventing inrush current peaks and voltage droop on shared 5 V supplies. |
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 |
|---|---|---|---|
| 74HCT541D-Q100 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5 V), slightly higher ICC (80 μA max vs. 160 μA for HC at 125 °C). | Better suited for interfacing legacy 5 V TTL logic; less suitable for 3.3 V-only systems due to marginal VIH margin. | Select when driving from 5 V TTL sources; avoid if interfacing 3.3 V microcontrollers without level translation. |
| SN74LVC244AQPWRQ1 | 3.3 V only (1.65–3.6 V), lower propagation delay (5.5 ns typ), but no dual OE - single OE controls all 8 outputs. | Optimized for high-speed 3.3 V buses (e.g., automotive infotainment); lacks independent enable partitioning for fault containment. | Prefer for 3.3 V systems requiring sub-10 ns timing; reject if dual-OE isolation or 5 V tolerance is required. |
Compared with 74HC541D-Q100, the 74HCT541D-Q100 offers better TTL interoperability but reduced noise margin in mixed-voltage designs, while the SN74LVC244AQPWRQ1 delivers superior speed and density at the cost of voltage flexibility and enable granularity - making the HC variant optimal for broad-voltage, safety-critical bus isolation.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks permanent damage per IEC 60134 limiting values, even briefly - sustained 6.5 V operation violates the datasheet's recommended conditions and voids AEC-Q100 qualification compliance.
Can OE1 and OE2 be tied together externally?
Yes, OE1 and OE2 may be connected to a single enable signal, simplifying control logic. Doing so maintains full 3-state functionality but eliminates independent enable capability. No additional pull-up or pull-down resistors are needed, as both inputs have CMOS-compatible input structure and negligible leakage (<0.1 μA).
Does this device support hot insertion or live bus swapping?
No - the 74HC541D-Q100 lacks explicit hot-swap protection features such as power-up 3-state or bus-hold. Input clamp diodes provide limited overvoltage tolerance (VCC + 0.5 V), but applying signals before VCC stabilization may cause latch-up or excessive ICC. Always sequence VCC before applying inputs in hot-swap scenarios.
How does the SO20 package's thermal derating affect maximum output current at 125 °C ambient?
At 125 °C ambient, junction temperature exceeds the 109 °C derating threshold by 16 K, reducing Ptot by 197 mW (12.3 mW/K × 16 K). With typical ICC = 160 μA and 8 outputs sourcing 7.8 mA each, power dissipation rises significantly - sustained full-load operation requires forced airflow or reduced output loading to maintain TJ < 150 °C.
