Product details
Overview
74VHCT541D-Q100 from Nexperia is an automotive-qualified octal non-inverting 3-state buffer/line driver in SO20 package, operating from 4.5 V to 5.5 V, with TTL-compatible inputs, propagation delay ≤5.5 ns (VCC = 5 V, CL = 15 pF), and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74VHCT541D-Q100 datasheet, 74VHCT541D-Q100 pinout, 74VHCT541D-Q100 application, or 74VHCT541D-Q100 equivalent, key selection criteria include TTL-level input compatibility, dual active-low output enable (OE0/OE1), bus-hold-free 3-state outputs, -40 °C to +125 °C operation, and SO20 package suitability for high-reliability automotive PCB layouts.
Technical Context
This device implements eight independent non-inverting buffers, each with output controlled by two global active-low 3-state enables (OE0 and OE1). Both enables must be LOW for output drive; either HIGH forces all Yn outputs into high-impedance state.
Input structure includes Schmitt-trigger action on all A0–A7 pins, enabling noise immunity on slow or noisy signal lines, and supports input voltages up to 5.5 V regardless of VCC - critical for mixed-voltage domain interfacing in automotive gateways and body controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - Ensures stable operation across automotive battery transients (e.g., load dump, cold crank). |
| Input Logic Type | TTL-compatible - Accepts standard 0.8 V / 2.0 V thresholds, eliminating level-shifting when interfacing with legacy microcontrollers. |
| Propagation Delay (tpd) | ≤5.5 ns @ VCC = 5 V, CL = 15 pF - Enables reliable timing in 20+ MHz parallel bus applications such as instrument cluster display drivers. |
| Output Drive Strength | ±8 mA @ VOH/VOL - Sufficient to drive 50 Ω transmission lines or fan-out to ≥10 LS-TTL loads without external buffering. |
| Operating Temperature | -40 °C to +125 °C - Validated for engine compartment and powertrain ECU placement per AEC-Q100 Grade 1 requirements. |
| ESD Protection | HBM >2000 V - Meets automotive system-level ESD robustness for assembly and field operation without additional protection circuitry. |
| Power Dissipation | 500 mW max (SO20) - Supports continuous operation in sealed enclosures with minimal thermal derating above 109 °C. |
Pinout & Package
74VHCT541D-Q100 uses the SOT163-1 (SO20) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm pitch, gull-wing leads, RoHS-compliant, qualified for reflow and wave soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE0, OE1 | Active-low 3-state enable inputs - Dual control allows partitioned bus access (e.g., OE0 for CAN subsystem, OE1 for LIN subsystem). |
| 2–9 | A0–A7 | Non-inverting data inputs - Schmitt-trigger inputs tolerate slow-rising signals from sensors or mechanical switches. |
| 10 | GND | Ground reference - Dedicated low-inductance return path for all internal logic and output stages. |
| 11–18 | Y0–Y7 | Buffered 3-state outputs - Outputs enter high-Z simultaneously when either OE is HIGH, preventing bus contention. |
| 20 | VCC | Positive supply - Must be decoupled locally with ≥100 nF ceramic capacitor to suppress switching noise on shared power rails. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling, HTOL, and ESD stress. |
| Dual active-low output enables | Independent control of two logical bus segments using OE0 and OE1 - enables hierarchical bus arbitration without external logic. |
| Input voltage tolerance beyond VCC | Accepts VI up to 5.5 V even at VCC = 4.5 V - simplifies interface to 5 V analog sensors or legacy peripherals without clamping diodes. |
| Low dynamic power dissipation | CPD = 12 pF - reduces switching current and heat generation in high-frequency data routing (e.g., infotainment display interfaces). |
| SO20 package with side-wettable flanks | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield and traceability in Tier-1 automotive production. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
Use Scenario: Driving multiplexed LED backlight rows and segment drivers from a low-power MCU with limited GPIO drive capability. IC Role / Device Role / Timing Role: Level-shifting, current-boosting, and bus isolation buffer between 3.3 V MCU and 5 V display driver ICs. Use Value: Eliminates need for discrete MOSFET arrays; Schmitt-trigger inputs reject switch bounce from door latch sensors feeding the same MCU. |
Use Scenario: Isolating SPI or parallel data buses between main cluster MCU and secondary graphics controller during firmware updates. IC Role / Device Role / Timing Role: 3-state bus driver enabling hot-swappable communication paths without signal contention. Use Value: Dual OE pins allow independent gating of tachometer vs. fuel gauge data lanes, reducing EMI during simultaneous updates. |
| Powertrain Control Unit (PCU) | Automotive Gateway |
Use Scenario: Buffering diagnostic address/data lines between engine ECU and OBD-II connector under high EMI conditions. IC Role / Device Role / Timing Role: Noise-immune signal repeater with TTL-compatible inputs matching legacy diagnostic tools. Use Value: Input hysteresis (≥0.5 V) rejects coupled alternator ripple; 125 °C rating ensures reliability near exhaust manifolds. |
Use Scenario: Interfacing multiple CAN/LIN transceivers to a central microcontroller via shared data/address buses. IC Role / Device Role / Timing Role: Bus driver enabling time-multiplexed access to transceiver configuration registers. Use Value: Low propagation delay (<6 ns) preserves timing margins in 1 Mbps CAN FD arbitration phases; SO20 footprint fits dense gateway PCB layouts. |
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 |
|---|---|---|---|
| 74LVC541APW-Q100 | CMOS input levels (VIH = 0.7×VCC), 1.65–5.5 V supply range, lower drive (±24 mA), smaller TSSOP20 package | Better suited for mixed-voltage domains (e.g., 1.8 V MCU ↔ 5 V peripheral), but lacks TTL input compatibility | Select when interfacing with modern low-voltage MCUs and board space is constrained. |
| SN74HCT541QPWRQ1 | Same TTL input thresholds, identical pinout, but TI's version specifies wider VCC range (4.5–5.5 V) and higher ICC max (100 μA vs. 80 μA) | Approved for automotive use per AEC-Q100 Grade 1, but lacks Nexperia's DHVQFN20 option and AOI-enabled SO20 variant | Select when requiring second-source availability with identical functional behavior and legacy TI design reuse. |
Compared with 74LVC541APW-Q100 and SN74HCT541QPWRQ1, the 74VHCT541D-Q100 uniquely combines TTL input compatibility, SO20 package with side-wettable flanks for AOI, and optimized propagation delay for high-speed automotive bus isolation - making it preferred for cost-sensitive, high-yield engine control and body electronics designs.

FAQ
What is the maximum clock frequency supported by 74VHCT541D-Q100?
The 74VHCT541D-Q100 is not a clocked device-it has no internal clock and operates asynchronously. Its usable data rate depends on propagation delay and load capacitance: with CL = 15 pF and VCC = 5 V, tpd ≤5.5 ns supports clean signal edges up to ~100 MHz toggle rate in point-to-point routing, assuming proper PCB layout and termination.
Can OE0 and OE1 be tied together for single-enable operation?
Yes-OE0 and OE1 may be connected to a common control signal. The functional table confirms that a HIGH on either input forces all outputs into high-impedance state; tying them together maintains full 3-state functionality while reducing GPIO usage, commonly applied in simplified bus architectures.
Does 74VHCT541D-Q100 require external pull-up or pull-down resistors on inputs?
No-inputs feature Schmitt-trigger action with defined hysteresis, eliminating need for external biasing. However, unused inputs must be terminated to VCC or GND to prevent floating states and excessive ICC; recommended practice is direct connection to GND for lowest power.
Is the SO20 package (SOT163-1) lead-free and RoHS compliant?
Yes-the 74VHCT541D-Q100 in SOT163-1 package is fully RoHS compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and qualified for standard reflow profiles up to 260 °C peak temperature.
