Product details

Overview

74HC7541DB,112 from Nexperia is an octal Schmitt-trigger buffer/line driver with 3-state outputs, dual active-low output enables (OE1, OE2), CMOS-level inputs, and operation across 2.0 V to 6.0 V supply. It transforms slow-rising/falling input signals into clean digital outputs and supports high-noise industrial bus interfacing at up to 85 MHz (t_pd = 11 ns @ V_CC = 6.0 V, C_L = 50 pF).

For engineers reviewing the 74HC7541DB,112 datasheet, 74HC7541DB,112 pinout, 74HC7541DB,112 application, or 74HC7541DB,112 equivalent, key selection criteria include Schmitt-trigger hysteresis (V_H = 0.3–0.5 V), dual-OE 3-state control timing (t_en/t_dis ≤ 41 ns), input clamp diode support for overvoltage-tolerant interfacing, and -40 °C to +125 °C extended temperature operation.

Technical Context

This device implements eight independent non-inverting buffer channels, each with Schmitt-trigger input thresholds (V_T+ = 4.2 V, V_T- = 1.8 V @ V_CC = 6.0 V) and TTL-compatible hysteresis (0.3–0.5 V). Its dual active-low output enables allow selective channel disabling without affecting other outputs.

The architecture includes input clamp diodes enabling safe interface to voltages exceeding V_CC when used with current-limiting resistors, and output drive capability of ±35 mA per pin with guaranteed VOL ≤ 0.4 V @ I_O = 7.8 mA and V_CC = 6.0 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V.
Input threshold hysteresis	0.3–0.5 V - rejects noise on slow edges in noisy industrial environments (e.g., motor control feedback lines).
Propagation delay	11 ns max @ V_CC = 6.0 V, C_L = 50 pF - enables reliable 85 MHz data throughput in parallel bus applications.
Output drive strength	±35 mA per pin - directly drives LEDs, relays, or multiple 74-series inputs without external buffers.
Operating temperature	-40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC backplanes.
Input leakage current	±0.1 μA max @ V_CC = 6.0 V - minimizes power loss in always-on sensor interface circuits.
Power dissipation capacitance	30 pF - enables accurate dynamic power estimation (P_D = C_PD × V_CC² × f_i × N) for thermal design.

Pinout & Package

74HC7541DB,112 is housed in a 20-lead SSOP package (SOT339-1), 7.2 mm × 5.3 mm body, 0.65 mm pitch, with exposed pad not electrically connected.

Pin/Terminal	Circuit Role	Design Meaning
1, 19	OE1, OE2	Active-low 3-state enable inputs - simultaneous LOW enables all eight outputs; either HIGH forces all outputs to high-impedance.
2–9	A0–A7	Buffer input pins - Schmitt-triggered to reject noise; clamp diodes permit safe overvoltage (e.g., 12 V sensor signals with series resistor).
10	GND	Ground reference - must be low-inductance connection to minimize switching noise coupling into logic thresholds.
11–18	Y0–Y7	Non-inverting buffered outputs - 3-state capable; drive strength supports fan-out of ≥20 LS-TTL loads.
20	V_CC	Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable Schmitt-trigger operation.

Key Features

Feature	Design Value
Wide supply range	2.0–6.0 V operation enables direct interface with 3.3 V microcontrollers and legacy 5 V systems without level shifters.
Schmitt-trigger inputs	0.5 V typical hysteresis ensures robust signal integrity on long PCB traces or cables subject to EMI.
Dual 3-state enables	Independent OE1/OE2 pins allow partitioned bus control - e.g., split memory/data bus segments without contention.
Input clamp diodes	Enable safe interfacing to voltages > V_CC (e.g., 12 V analog sensors) using simple series current-limiting resistors.
High noise immunity	CMOS input structure with 40% V_CC noise margin ensures reliable operation in electrically noisy factory-floor environments.

Applications

Industrial Bus Interface

Motor Control Feedback

Use Scenario: Isolating and conditioning encoder quadrature signals before feeding to a motion controller FPGA.

IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow, noisy A/B channel edges; 3-state outputs allow shared bus access during diagnostics.

Use Value: Eliminates false edge detection caused by cable-induced ringing; hysteresis prevents chatter during mechanical vibration.

Use Scenario: Level-shifting and noise filtering hall-effect sensor outputs in BLDC motor commutation circuits.

IC Role / Device Role / Timing Role: Non-inverting buffer with overvoltage-tolerant inputs interfaces 12 V sensors to 3.3 V MCU GPIOs.

Use Value: Clamp diodes + series resistor replace discrete protection circuitry, reducing BOM count and board area.

Legacy System Expansion

Test Equipment Signal Conditioning

Use Scenario: Adding parallel I/O capability to an aging 8-bit microcontroller-based data acquisition system.

IC Role / Device Role / Timing Role: Octal buffer expands address/data bus drive capability while maintaining TTL/CMOS compatibility.

Use Value: Supports fan-out to 20+ LS-TTL loads without timing degradation; dual OE allows dynamic bus arbitration.

Use Scenario: Cleaning and amplifying low-amplitude, slow-rising waveforms from passive probes in automated test fixtures.

IC Role / Device Role / Timing Role: Schmitt-trigger input converts distorted analog edges into precise digital timing references.

Use Value: Enables sub-10 ns edge jitter reduction for accurate timestamping of DUT response events.

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
74HC7540D,653	Inverting outputs; identical pinout, supply, and timing specs.	Requires logic inversion in downstream logic; unsuitable where signal polarity must be preserved.	Select only when system-level inversion is acceptable or compensated elsewhere.
SN74LVTH162244DGGR	16-bit, 3.3 V only, TTL-compatible inputs, higher drive (±24 mA), different pinout.	Not pin-compatible; requires PCB redesign; suited for high-speed 3.3 V systems with tighter timing budgets.	Choose for new 3.3 V designs needing higher channel count and lower propagation delay (2.5 ns).

Compared with 74HC7541DB,112, the 74HC7540D,653 offers identical functionality except output polarity, while SN74LVTH162244DGGR provides double the channel count and faster speed but sacrifices voltage flexibility and pin compatibility - making it suitable only for green-field 3.3 V designs.

FAQ

What is the maximum clock frequency supported by 74HC7541DB,112?

The device does not operate as a clocked sequential element but as a combinational buffer. Its maximum usable data rate is determined by propagation delay: t_pd = 11 ns @ V_CC = 6.0 V, enabling reliable 45 MHz toggle rate on individual lines. For parallel bus use, setup/hold margins must be verified against driving source timing.

Can 74HC7541DB,112 interface 5 V logic to a 3.3 V microcontroller?

Yes - its CMOS inputs accept 3.3 V as valid HIGH (VIH ≥ 3.15 V @ V_CC = 4.5 V), and outputs swing rail-to-rail (VOH ≥ 4.4 V @ V_CC = 4.5 V), so level translation is achieved by powering V_CC at 4.5 V and using current-limiting resistors on inputs if interfacing to 5 V sources with clamp diodes enabled.

Does 74HC7541DB,112 require external pull-up resistors on outputs?

No - outputs are push-pull CMOS and do not require pull-ups. When in 3-state (OE1=OE2=HIGH), outputs present high impedance (> 10 MΩ), eliminating bus contention. Pull-ups are only needed if open-drain behavior is desired, which this device does not provide.

Is 74HC7541DB,112 qualified for automotive applications?

No - although rated for -40 °C to +125 °C, it is not AEC-Q100 qualified and lacks automotive-specific reliability testing (e.g., HTOL, ESD HBM ≥ 8 kV). Nexperia explicitly states non-automotive qualification in its legal disclaimers; use in automotive systems requires formal validation by the end customer.
