Key Features
- Octal 8-bit non-inverting 3-state outputs with dual active-low output enable pins for flexible bus multiplexing and data isolation in multi-master systems
- High-speed CMOS HC-family technology delivering low quiescent current with fast switching edges suitable for 2 V to 6 V powered digital bus architectures
- RoHS-compliant lead-free G4 green packaging with 20-pin SOIC footprint enabling reliable automated assembly in modern eco-compliant designs
Applications
The CD74HC541M96G4 is used as a unidirectional data bus buffer in microprocessor and microcontroller memory bus expansion, address latching, and I/O port isolation circuits where eight data lines must be driven or tristate-isolated as a group. It is applied in FPGA and CPLD peripheral interfaces, backplane bus systems, and data acquisition modules requiring clean signal buffering across board-to-board connectors. The dual output enable pins also make it suitable for bus arbitration schemes where two independent enable sources control bus access.

Frequently Asked Questions
What is the difference between the CD74HC541 and CD74HC541 non-inverting buffer?
The CD74HC541 is a non-inverting octal buffer, meaning each output matches the logic state of its corresponding input when enabled. This contrasts with the CD74HC540, which is an inverting variant. The non-inverting CD74HC541 is preferred when signal polarity must be preserved through the buffer stage.
How does the dual output enable work on the CD74HC541M96G4?
The CD74HC541M96G4 has two independent active-low output enable inputs (OE1 and OE2), both of which must be asserted low to enable all eight outputs. If either pin is deasserted high, all outputs enter the high-impedance state, disconnecting the driver from the bus without affecting the input logic.
What package does the CD74HC541M96G4 come in?
The CD74HC541M96G4 is housed in a 20-pin SOIC (Small Outline IC) surface-mount package, JESD-30 code R-PDSO-G20. The M96 portion indicates tape and reel packaging for automated pick-and-place assembly, and the G4 suffix confirms RoHS lead-free compliance.
Is the CD74HC541M96G4 RoHS compliant?
Yes. The G4 suffix and Pbfree Code of Yes confirm that the CD74HC541M96G4 is RoHS compliant and uses lead-free solder finish (JESD-609 Code e4), meeting European Union RoHS directives and other international environmental regulations for hazardous substances in electronics.
What logic family is the CD74HC541M96G4 and what supply voltages does it support?
The CD74HC541M96G4 belongs to the HC/UH high-speed CMOS logic family, which typically operates from 2 V to 6 V. This range covers 3.3 V and 5 V supply rails, providing compatibility with both modern low-voltage microcontrollers and legacy 5 V TTL-based digital systems.
