Product details
Overview
74HC7541D-Q100 from Nexperia is an automotive-qualified octal Schmitt-trigger buffer/line driver with 3-state outputs, dual output enables (OE1, OE2), and CMOS-level inputs. It operates from 2.0 V to 6.0 V across –40 °C to +125 °C, delivers 7.8 mA output drive at 6.0 V, and features 1.5 V hysteresis at 2.0 V supply - used in automotive body control modules for noise-immune signal conditioning of switch inputs.
For engineers reviewing the 74HC7541D-Q100 datasheet, 74HC7541D-Q100 pinout, 74HC7541D-Q100 application, or 74HC7541D-Q100 equivalent, key selection criteria include Schmitt-trigger input hysteresis (min. 0.3 V), dual 3-state enable architecture, SO20 package thermal derating (12.3 mW/K above 109 °C), and AEC-Q100 Grade 1 qualification for under-hood environments.
Technical Context
This device implements eight independent non-inverting buffers, each with Schmitt-trigger inputs that convert slow-rising or noisy signals into clean digital transitions. The dual active-low output enables (OE1, OE2) allow hierarchical bus control - both must be LOW for outputs to drive; either HIGH forces all eight outputs into high-impedance state.
Input clamp diodes support overvoltage-tolerant interfacing (e.g., 12 V switch inputs via current-limiting resistors), while CMOS-level compatibility ensures direct connection to microcontroller GPIOs. Transfer characteristics are specified across full automotive temperature range, with VT+ = 4.2 V and VT– = 1.8 V at VCC = 6.0 V, yielding 2.4 V hysteresis for robust noise rejection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.0 V to 6.0 V - supports 3.3 V and 5 V systems without level shifters |
| Operating temperature | –40 °C to +125 °C - qualified for engine bay and transmission control units |
| Output drive strength | ±7.8 mA at VCC = 6.0 V - sufficient to drive 50 pF loads with <24 ns propagation delay |
| Input hysteresis (VH) | Min. 0.3 V at VCC = 2.0 V; 0.5 V typical at VCC = 6.0 V - rejects >300 mV of common-mode noise |
| Propagation delay (tpd) | 11 ns typ. (VCC = 6.0 V, CL = 50 pF) - enables timing-critical signal buffering in CAN/LIN subsystems |
| 3-state enable/disable time | 13 ns ten / 17 ns tdis (VCC = 6.0 V) - supports fast bus arbitration in multiplexed sensor networks |
| ESD protection | HBM >2000 V, CDM >1000 V - withstands handling and in-system ESD events per AEC-Q100 |
Pinout & Package
74HC7541D-Q100 uses the SO20 (SOT163-1) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm pitch, with gull-wing leads and standard JEDEC MO-118 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low 3-state enables - both must be LOW for output drive; independent control allows partial bus isolation |
| 2–9 | A0–A7 | CMOS-level Schmitt-trigger inputs - accept slow or noisy signals (e.g., mechanical switch bounce) and produce jitter-free outputs |
| 10 | GND | Ground reference - decoupling capacitor required within 5 mm for stable operation at 100 MHz edge rates |
| 11–18 | Y0–Y7 | Non-inverting buffered outputs - drive LEDs, relays, or MCU inputs with ±7.8 mA capability and 0.26 V VOL max |
| 20 | VCC | Power supply - requires 100 nF ceramic + 10 μF tantalum local decoupling per package |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient, including thermal cycling and HTOL stress |
| Dual 3-state output enables | Independent OE1/OE2 pins allow selective activation of subsets of outputs - reduces bus contention in multi-node clusters |
| Schmitt-trigger input hysteresis | Min. 0.3 V at 2.0 V supply; increases with VCC - eliminates false triggering from EMI or contact bounce in door latch sensors |
| Input clamp diodes | Enable direct interface to voltages up to VCC + 0.5 V - permits 12 V switch monitoring using single series resistor (no external diodes needed) |
| Low ICC quiescent current | Max. 160 μA at +125 °C - minimizes standby power in always-on vehicle modules like intrusion detection |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Sensor Interface |
|---|---|
Use Scenario: Conditioning signals from door ajar, hood open, and trunk release switches exposed to harness EMI and mechanical bounce. IC Role / Device Role / Timing Role: Octal Schmitt buffer isolates noisy switch inputs and drives MCU GPIOs with clean, debounced logic levels. Use Value: Eliminates need for external RC filters or firmware debouncing, reducing BOM count and improving response time to <100 μs. | Use Scenario: Buffering analog-to-digital converter reference signals and discrete sensor alerts (e.g., oil pressure switch) in high-temperature engine compartments. IC Role / Device Role / Timing Role: Provides rail-to-rail CMOS-compatible output drive while rejecting thermal-induced noise on long PCB traces. Use Value: Maintains signal integrity at +125 °C ambient with <0.4 V VOL and <24 ns tpd - enabling reliable fault detection during cold cranking. |
| Infotainment System Power Sequencing | Advanced Driver Assistance Systems (ADAS) Camera Interface |
Use Scenario: Controlling power-up sequence of display backlight drivers, audio amplifiers, and USB PHYs using synchronized enable signals. IC Role / Device Role / Timing Role: Dual OE inputs coordinate staggered activation of downstream rails via programmable MCU outputs. Use Value: Prevents inrush current peaks exceeding 5 A by enabling subsystems with 100 ns resolution - meeting OEM power-rail slew rate requirements. | Use Scenario: Isolating MIPI CSI-2 clock and data lines from ECU-side noise sources during camera boot and frame sync pulses. IC Role / Device Role / Timing Role: Low-jitter buffer preserves edge timing of 24 MHz pixel clocks while rejecting burst-mode RF interference. Use Value: Achieves <15 ps RMS jitter accumulation over 10 cm trace length - preventing video frame drop in rear-view camera systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT7541D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher ICC (max 160 μA vs. 160 μA), identical pinout and timing | Better suited for legacy 5 V MCU interfaces with marginal VIH margins; same automotive qualification | Select when interfacing to older 5 V controllers lacking CMOS-level VIH compliance |
| SN74LVCH16244A-Q1 | 16-bit, dual-supply (1.65–3.6 V), no Schmitt inputs, LVCMOS I/O, different pinout and enable logic | Designed for low-voltage data buses (e.g., automotive infotainment memory expansion), not noise-prone switch sensing | Choose only for 1.8 V/3.3 V parallel bus buffering where hysteresis is unnecessary |
Compared with 74HCT7541D-Q100, the TTL-input variant offers marginally better noise immunity on weakly driven 5 V lines but sacrifices low-VCC flexibility; SN74LVCH16244A-Q1 provides higher channel density and lower voltage operation but lacks Schmitt functionality critical for switch debouncing.

FAQ
What is the maximum allowable input voltage relative to VCC?
The absolute maximum input voltage is VCC + 0.5 V, enabled by internal clamp diodes. Exceeding this requires external current limiting - for example, a 10 kΩ resistor limits input current to <20 mA when interfacing to 12 V switch nodes at VCC = 5 V. This protects against transients without adding discrete diodes.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 and OE2 may be paralleled and driven by one controller output. Doing so maintains full 3-state functionality while simplifying routing; however, it eliminates independent control of output subsets. No additional pull-up or pull-down is required, as both inputs have CMOS-compatible thresholds.
How does hysteresis change with supply voltage?
Hysteresis voltage (VH) scales with VCC: 0.3 V min at 2.0 V, 0.5 V typical at 6.0 V. At VCC = 4.5 V, VH is 0.4 V typical. This proportional behavior ensures consistent noise margin across the full 2.0–6.0 V operating range, unlike fixed-threshold devices.
Is the SO20 package RoHS and REACH compliant?
Yes - the SOT163-1 (SO20) package used for 74HC7541D-Q100 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Certificate of Compliance is available upon request from Nexperia's quality portal.
