Product details
Overview
74HC7541D,118 from Nexperia is an 8-bit non-inverting Schmitt-trigger buffer/line driver with dual 3-state output enables (OE1, OE2), CMOS-level inputs, and SO20 package. It operates from 2.0 V to 6.0 V, delivers ±35 mA output drive, supports -40 °C to +125 °C ambient, and features input clamp diodes for overvoltage-tolerant interfacing in industrial bus line conditioning.
For engineers reviewing the 74HC7541D,118 datasheet, 74HC7541D pinout, 74HC7541D application, or 74HC7541D equivalent, this device is selected for noise-immune signal buffering in legacy TTL/CMOS mixed-voltage systems, high-impedance bus isolation, and slow-edge signal cleanup in sensor interface and control logic circuits.
Technical Context
The 74HC7541D implements dual active-low output enables controlling eight independent non-inverting buffered outputs. Its Schmitt-trigger inputs provide 0.3 V to 0.5 V hysteresis (VH) across 2.0–6.0 V supply, enabling reliable digitization of slow-rising analog or noisy digital signals without external RC filtering.
Each output drives up to ±35 mA while maintaining VOH ≥ 5.48 V (VCC = 6.0 V, IO = −7.8 mA) and VOL ≤ 0.26 V (VCC = 6.0 V, IO = 7.8 mA). Input leakage remains ≤ ±0.1 μA at 25 °C, and propagation delay is 11–20 ns (VCC = 6.0 V, CL = 50 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Output Drive | ±35 mA - Sufficient to directly drive LEDs, relays, or multiple 74-series inputs without external buffers. |
| Input Hysteresis | 0.3 V to 0.5 V - Rejects up to 500 mV of noise on slow-rising signals (e.g., mechanical switch bounce, thermistor outputs). |
| Propagation Delay | 11 ns (min) / 20 ns (max) at VCC = 6.0 V - Supports >25 MHz data rates in clean bus environments. |
| Operating Temp | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control enclosures. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Survives handling and board-level ESD events without latch-up or parameter shift. |
| Power Dissipation | 500 mW (SO20, ≤109 °C) - Allows full 8-channel operation at 6 V with minimal thermal derating in standard PCB layouts. |
Pinout & Package
74HC7541D,118 uses the SO20 (SOT163-1) plastic small outline package: 20-pin, 7.5 mm body width, 1.27 mm pitch, gull-wing leads. Thermal resistance θJA = 82 K/W (JEDEC-standard board).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low 3-state enable inputs - Both must be LOW to activate outputs; either HIGH forces all Yn into high-Z. |
| 2–9 | A0–A7 | Non-inverting Schmitt-trigger inputs - Accept slow edges (unlimited rise/fall time); clamp diodes allow VI > VCC. |
| 10 | GND | Ground reference - Must be low-impedance return path for all 8 outputs and internal logic. |
| 11–18 | Y0–Y7 | Buffered non-inverting outputs - Each independently driven; high-Z state isolates downstream loads during bus sharing. |
| 20 | VCC | Positive supply - Powers internal logic and output drivers; bypass capacitor required within 10 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0–6.0 V operation - Eliminates need for separate 3.3 V and 5 V supply rails in mixed-voltage systems. |
| Schmitt-trigger inputs | 0.3–0.5 V hysteresis - Converts noisy or slow analog-like signals (e.g., potentiometer wipers, open-collector sensors) into clean digital logic levels. |
| Dual 3-state control | Independent OE1/OE2 pins - Enables hierarchical bus arbitration or selective channel disabling without affecting other outputs. |
| Input clamp diodes | VI tolerance up to VCC + 0.5 V - Permits direct connection to 12 V sensor outputs using only series current-limiting resistors. |
| High noise immunity | CMOS-level input thresholds scaled to VCC - Maintains >40% noise margin across full voltage and temperature range. |
Applications
| Industrial Sensor Interface | Legacy Bus Line Driver |
|---|---|
|
Use Scenario: Conditioning output from a slow-rising RTD-to-digital converter with 100 µs rise time and 200 mV peak noise. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans signal edges before feeding to microcontroller GPIO with internal pull-ups. Use Value: Eliminates need for external RC filter and debouncing firmware; reduces BOM count by one passive per channel. |
Use Scenario: Driving a 24 V industrial CAN transceiver input from a 3.3 V microcontroller with long PCB traces. IC Role / Device Role / Timing Role: Level-shifting line driver providing 35 mA sink/source to overcome trace capacitance and EMI coupling. Use Value: Ensures fast edge integrity (>20 MHz effective bandwidth) and noise rejection on factory-floor wiring harnesses. |
| Motor Control Logic Isolation | Test Equipment Signal Multiplexing |
|
Use Scenario: Isolating microcontroller I/O from high-noise gate-driver feedback lines in a 3-phase inverter. IC Role / Device Role / Timing Role: 3-state buffer decouples MCU pins during fault conditions via OE assertion. Use Value: Prevents latch-up or false triggering during power-stage switching transients; enables safe hot-swap diagnostics. |
Use Scenario: Routing 8 DUT signals through a boundary-scan test fixture with shared JTAG TDI/TDO paths. IC Role / Device Role / Timing Role: Bidirectional bus buffer controlled by test sequencer to isolate DUT from tester during configuration. Use Value: Reduces crosstalk between adjacent channels; maintains signal integrity at 10 MHz scan clock rates. |
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,118 | TTL-compatible inputs (VIH = 2.0 V min); identical SO20 package and pinout. | Better interoperability with 5 V TTL logic families; slightly higher ICC at 5.5 V. | Select when interfacing legacy 74LS/74ALS devices or where input threshold stability across VCC variation is critical. |
| SN74LVCH16244ADGGR | 16-bit, 3.3 V only (1.65–3.6 V), LVCMOS inputs, TSSOP56 package. | Higher channel density but incompatible voltage range and footprint; no Schmitt inputs. | Use only if migrating to 3.3 V-only systems with space-constrained layouts and no slow-edge signal conditioning needs. |
Compared with 74HCT7541D,118, the TTL-input variant offers tighter VIH/VIL margins in mixed-logic systems but sacrifices 2.0 V operation; SN74LVCH16244ADGGR provides double the channels at lower voltage but removes Schmitt functionality and requires redesign of PCB layout and power delivery.

FAQ
Can 74HC7541D,118 drive a 50 pF load at 10 MHz without signal degradation?
Yes. With tpd = 11–20 ns (VCC = 6.0 V, CL = 50 pF) and tt = 4–10 ns, it meets setup/hold timing for 10 MHz clocks. Output drive capability (±35 mA) ensures <10% overshoot on 50 pF loads with proper PCB routing and local VCC decoupling.
What happens if both OE1 and OE2 are left floating?
OEn pins have no internal pull-up/down; floating states cause unpredictable output behavior. Per datasheet, OE1 and OE2 must be actively driven LOW to enable outputs or HIGH to force high-Z. Tie unused enables to VCC via 10 kΩ resistor for default disable.
Does the 74HC7541D,118 support hot insertion into a live backplane?
No. While input clamp diodes tolerate VI > VCC, the device lacks hot-swap protection circuitry. Applying VCC after signal inputs may forward-bias internal diodes, causing excessive IIK current. Power sequencing (VCC first, then signals) is mandatory.
How does hysteresis vary with supply voltage?
VT+ and VT− scale linearly with VCC: VH = VT+ − VT− = 0.3 V (min) to 0.5 V (max) across 2.0–6.0 V. At VCC = 2.0 V, VH = 0.3 V; at VCC = 6.0 V, VH = 0.5 V. This ensures consistent noise margin percentage (~15–25%) regardless of rail voltage.
