Product details
Overview
74HC7541PW,118 from Nexperia is an octal Schmitt-trigger buffer/line driver with 3-state outputs, dual active-low output enables (OE1, OE2), and CMOS-level inputs. It operates from 2.0 V to 6.0 V, delivers ±35 mA output drive, supports -40 °C to +125 °C ambient range, and transforms slow-rising input signals into clean digital outputs-used in industrial sensor interface and bus buffering applications.
For engineers reviewing the 74HC7541PW,118 datasheet, 74HC7541PW,118 pinout, 74HC7541PW,118 application, or 74HC7541PW,118 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.3–0.5 V at VCC = 6.0 V), propagation delay (11–32 ns at VCC = 6.0 V), 3-state enable/disable timing (13–41 ns), TSSOP20 package thermal derating (10.0 mW/K above 100 °C), and input clamp diode support for overvoltage-tolerant interfacing.
Technical Context
This device implements eight independent non-inverting buffers, each with Schmitt-trigger input thresholds (VT+ = 4.2 V, VT− = 1.8 V at VCC = 6.0 V) and hysteresis of 0.3–0.5 V. Its dual active-low output enables allow selective tri-state control of output groups, supporting bus arbitration and load isolation in shared-data-path systems.
The architecture includes input clamp diodes enabling current-limiting resistor use for interfacing to voltages exceeding VCC, and CMOS-level input compatibility ensures direct connection to HC/HCT logic families without level-shifting. Static current consumption remains below 160 μA across full temperature range at VCC = 6.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables interoperability with 3.3 V and 5 V logic domains without external regulators. |
| Output Drive Current | ±35 mA - Sufficient to directly drive multiple TTL loads or moderate PCB traces without external buffers. |
| Propagation Delay | 11–32 ns at VCC = 6.0 V - Supports reliable operation up to ~15 MHz clocked data paths in non-critical timing applications. |
| Schmitt Hysteresis | 0.3–0.5 V at VCC = 6.0 V - Rejects >500 mV of noise on slow analog-like inputs (e.g., mechanical switch debouncing). |
| Input Clamp Current | ±20 mA - Allows safe interface to signals up to VCC + 0.5 V using series resistors ≥25 Ω. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control environments. |
| Power Dissipation | 500 mW (derates 10.0 mW/K above 100 °C in TSSOP20) - Limits maximum continuous output loading in thermally constrained layouts. |
Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-pin, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE1, OE2 | Active-low output enable controls - Both must be LOW for outputs Y0–Y7 to drive; either HIGH forces all outputs to high-impedance. |
| 2–9 | A0–A7 | Non-inverting Schmitt-trigger inputs - Accept slow-rising signals (e.g., from sensors or switches); internal hysteresis prevents chatter. |
| 10 | GND | Ground reference - Must be low-impedance connection; decoupling capacitor required near VCC pin. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - Output state mirrors A0–A7 when OEs are active; high-Z otherwise for bus sharing. |
| 20 | VCC | Positive supply - Requires local 100 nF ceramic decoupling; voltage must remain within 2.0–6.0 V during operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation - Eliminates need for separate voltage rails when interfacing mixed-voltage subsystems. |
| Schmitt-trigger inputs | VT+ = 4.2 V / VT− = 1.8 V at VCC = 6.0 V - Enables robust signal conditioning of noisy or slow analog-sourced digital signals. |
| Dual 3-state enables | OE1 and OE2 both active-low - Allows independent control of two output subsets or redundant enable paths for safety-critical designs. |
| Input clamp diodes | Supports VI up to VCC + 0.5 V with current limiting - Permits direct connection to 12 V sensor outputs using 470 Ω series resistors. |
| High noise immunity | CMOS input threshold ratio >60 % of VCC - Resists EFT bursts and radiated RF coupling in industrial enclosures. |
Applications
| Industrial Sensor Interface | Legacy Bus Buffering |
|---|---|
Use Scenario: Interfacing mechanical limit switches and analog-output pressure sensors to a 5 V microcontroller GPIO port. IC Role / Device Role / Timing Role: Signal conditioning and level translation - converts slow, noisy switch bounce or sensor output edges into clean, jitter-free logic levels. Use Value: Eliminates need for external RC filters or software debouncing; hysteresis rejects >500 mV noise without increasing latency. | Use Scenario: Isolating and driving legacy parallel address/data buses between FPGA and EEPROM or display controller. IC Role / Device Role / Timing Role: Bidirectional bus driver with 3-state control - enables time-multiplexed access by multiple masters while preventing contention. Use Value: Dual OE pins allow synchronized enable/disable of two bus segments; ±35 mA drive sustains signal integrity over 15 cm traces. |
| Motor Control Feedback | Test Equipment Signal Conditioning |
Use Scenario: Converting hall-effect encoder quadrature signals in a BLDC motor controller operating at 125 °C junction temperature. IC Role / Device Role / Timing Role: High-temperature-compatible buffer with noise rejection - ensures clean edge detection despite EMI from PWM-driven power stages. Use Value: -40 °C to +125 °C rating matches motor housing thermal profile; 0.5 V hysteresis suppresses switching noise induced on encoder cables. | Use Scenario: Conditioning low-amplitude, slow-rising waveforms from function generator outputs before feeding to DUT input comparators. IC Role / Device Role / Timing Role: Input squaring and amplitude restoration - reshapes distorted or attenuated signals into rail-to-rail logic-compatible pulses. Use Value: Input capacitance of 3.5 pF minimizes loading on source; propagation delay variation <12 ns ensures deterministic timing alignment across all 8 channels. |
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 |
|---|---|---|---|
| 74HCT7541PW,118 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and timing | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy logic families | Select when interfacing to 74LS or older microcontrollers with weak high-level drive capability |
| SN74LVTH162244DGGR | 16-bit, dual 8-bit, LVTH family, 3.3 V only, higher drive (±24 mA), different pinout | Requires PCB redesign; used in high-density 3.3 V systems needing greater channel count | Choose only if migrating to 3.3 V domain and requiring double channel density with lower supply voltage |
Compared with 74HC7541PW,118, the 74HCT7541PW,118 offers guaranteed TTL input compatibility at 5 V but sacrifices 2.0–3.3 V operation; SN74LVTH162244DGGR provides double channel count and lower voltage operation but demands layout revision and lacks Schmitt inputs on all channels.

FAQ
What is the maximum allowable input voltage relative to VCC?
The absolute maximum input voltage is VCC + 0.5 V, enabled by integrated clamp diodes. To avoid exceeding the ±20 mA clamp current limit, a series current-limiting resistor must be used when interfacing to voltages above VCC. For example, connecting a 12 V sensor to a 5 V-powered 74HC7541PW requires a minimum 350 Ω resistor (7 V / 20 mA) to stay within specification.
How does the dual output enable (OE1/OE2) function in practice?
Both OE1 and OE2 are active-low and ORed internally: only when both are LOW do outputs Y0–Y7 become active. If either OE is HIGH, all eight outputs enter high-impedance state. This allows fail-safe bus control-e.g., one OE tied to system reset (active during fault), the other to processor control-ensuring outputs default to high-Z on power-up or error.
Can this device drive a 50 pF load at 10 MHz without signal degradation?
Yes: at VCC = 6.0 V and CL = 50 pF, propagation delay is 11–20 ns and transition time is 4–10 ns, yielding a usable bandwidth >25 MHz. With 3.5 pF input capacitance and CPD = 30 pF, dynamic power at 10 MHz is ~11 μW per input, well within the 500 mW package limit. Layout best practices (short traces, ground plane) ensure integrity.
Is the TSSOP20 package RoHS-compliant and lead-free?
Yes: the 74HC7541PW,118 in SOT360-1 (TSSOP20) package is manufactured per RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) termination. The device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30 °C/60 % RH without dry-pack requirements.
