Product details
Overview
74HCT541PW-Q100 from Nexperia is an automotive-qualified octal non-inverting 3-state buffer/line driver in TSSOP20 package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, −40 °C to +125 °C temperature range, and propagation delay of 15 ns (typ) at VCC = 4.5 V. It serves as a bidirectional bus interface or signal isolation device in automotive body control modules and infotainment data routing.
For engineers reviewing the 74HCT541PW-Q100 datasheet, 74HCT541PW-Q100 pinout, 74HCT541PW-Q100 application, or 74HCT541PW-Q100 equivalent, key selection criteria include dual active-low output enables (OE1/OE2), ±6 mA output drive capability, high-impedance OFF-state leakage < ±5 μA, and AEC-Q100 Grade 1 qualification for under-hood electronics.
Technical Context
This device implements eight identical non-inverting buffer circuits with independent input clamping diodes enabling overvoltage-tolerant interfacing. Its dual output-enable architecture allows selective activation of two groups of outputs-critical for bus arbitration in multi-master systems.
Input thresholds are fixed at VIH = 2.0 V (min) and VIL = 0.8 V (max) across temperature, ensuring robust TTL-level compatibility. Output switching is characterized by tpd = 15–42 ns (depending on VCC and load), tdis = 21–53 ns, and tt = 5–18 ns, supporting reliable 20 MHz bus operation under worst-case conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across automotive battery transients (e.g., cold-crank, load-dump). |
| Operating Temperature | −40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for engine bay and powertrain applications. |
| Propagation Delay | 15 ns (typ) at VCC = 4.5 V, CL = 50 pF - supports synchronous data transfer up to ~20 MHz on PCB traces ≤10 cm. |
| Output Drive | ±6.0 mA (IOH/IOL) - sufficient to drive standard CMOS/TTL loads and moderate PCB capacitance without external buffering. |
| Input Thresholds | VIH = 2.0 V (min), VIL = 0.8 V (max) - guarantees reliable recognition of legacy TTL logic levels across full temperature range. |
| OFF-State Leakage | ±5.0 μA (max) at VCC = 5.5 V - prevents unintended current paths during 3-state hold, critical for low-power sleep modes. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive ESD immunity requirements per ISO 10605. |
Pinout & Package
TSSOP20 (SOT360-1) package: 20-pin thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, surface-mount compatible with automated assembly and thermal performance suitable for under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable inputs - simultaneous LOW activates all eight outputs; independent control enables partial bus gating. |
| 2–9 | A0–A7 | Data inputs - TTL-compatible, with clamp diodes allowing safe interfacing to signals exceeding VCC (e.g., 12 V sensor lines via current-limiting resistors). |
| 10 | GND | Ground reference - dedicated low-inductance return path essential for noise immunity in automotive harness environments. |
| 11–18 | Y0–Y7 | Non-inverting 3-state outputs - high-impedance state (Z) isolates downstream circuitry during bus contention or power-down sequences. |
| 20 | VCC | Supply voltage input - decoupling capacitor placement near this pin minimizes supply bounce during simultaneous output switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including temperature cycling, humidity, and mechanical shock tests. |
| Dual independent output enables | OE1 and OE2 allow partitioned bus control - e.g., Y0–Y3 driven while Y4–Y7 held high-Z for mixed-speed subsystem interfacing. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V ensure interoperability with legacy microcontrollers and discrete logic without level-shifting. |
| Input clamp diodes | Enable direct connection to voltages > VCC (e.g., 5 V or 12 V signals) using series current-limiting resistors - eliminates need for external protection diodes. |
| Low dynamic power dissipation | CPD = 39 pF - limits switching power to < 1 mW at 10 MHz with 50 pF load, reducing thermal load in dense ECUs. |
Applications
| Automotive Body Control Module | Infotainment System Data Bus |
|---|---|
Use Scenario: Isolating microcontroller GPIOs from door lock actuators, window lift motors, and mirror controls. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state outputs acts as bidirectional bus driver and signal conditioner between MCU and high-current peripheral drivers.

IC Role / Device Role / Timing Role: Line driver providing impedance matching and noise margin enhancement on 5 V parallel control buses. Use Value: 15 ns propagation delay ensures setup/hold timing compliance for 20 MHz control interfaces, preventing metastability in display initialization sequences. |
| Engine Control Unit I/O Expansion | ADAS Camera Interface Buffer |
Use Scenario: Extending GPIO count of main ECU processor to manage solenoid valves, pressure sensors, and diagnostic LEDs. IC Role / Device Role / Timing Role: Octal buffer provides level translation and fan-out capability for TTL-level sensor inputs and actuator command outputs.

IC Role / Device Role / Timing Role: 3-state buffer decouples camera-side logic during power-up/down transitions to prevent back-driving and latch-up. Use Value: ±5 μA max OFF-state leakage ensures no DC loading on powered-down camera rails, preserving reset integrity and avoiding false wake events. |
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 |
|---|---|---|---|
| SN74HCT541QPWRQ1 | TI part with identical pinout, same AEC-Q100 Grade 1 rating, but higher ICC (max 160 μA vs. 80 μA typ) and slightly slower tpd (18 ns typ). | Valid for same automotive temperature range but exhibits higher static current in always-on modules like gateway ECUs. | Select when TI ecosystem alignment or existing footprint reuse is prioritized over minimal quiescent power. |
| 74HCT541D-Q100 | Same Nexperia silicon in SO20 (SOT163-1) package - larger footprint (7.5 mm width), higher thermal resistance (12.3 mW/K derating above 109 °C). | Suitable for less space-constrained boards where manual rework or legacy SOIC tooling is required. | Choose for compatibility with existing SOIC assembly lines or when board-level thermal mass mitigates TSSOP's lower power dissipation limit. |
Compared with SN74HCT541QPWRQ1, the 74HCT541PW-Q100 offers lower typical supply current and faster propagation, improving power efficiency in duty-cycled automotive nodes; versus 74HCT541D-Q100, it delivers superior thermal performance and board-area savings in modern compact ECUs.

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 4.5 V to 5.5 V to ensure AEC-Q100 compliance, parametric stability, and long-term reliability. Exceeding 5.5 V risks accelerated parametric drift and violates automotive qualification limits.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 and OE2 may be connected to a common control signal without adverse effects. The internal logic requires both to be LOW for output activation; tying them simplifies design in applications needing uniform 3-state control across all eight channels.
Does this device support hot insertion or live bus connection?
No - while input clamp diodes tolerate overvoltage, the device lacks true hot-swap protection features such as slew-rate limiting or back-drive prevention. Live insertion into an active bus may cause transient glitches or exceed IOZ limits if outputs are enabled before VCC stabilizes.
How does the 74HCT541PW-Q100 differ from the 74HC541PW-Q100 variant?
The 74HCT541PW-Q100 uses TTL-compatible input thresholds (VIH ≥ 2.0 V), whereas the 74HC541PW-Q100 requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). This makes the HCT version interoperable with legacy 5 V TTL microcontrollers without level shifters, unlike the HC variant.
