Frequently asked questions
Are the 74HC541D and 74HC541D,653 functionally identical?
Yes. Both are octal non-inverting buffers/line drivers with 3-state outputs from the 74HC logic family. The 74HC541D,653 is a manufacturer orderable part number that includes a packing/ordering suffix, while 74HC541D is the base type designation. They share the same die, logic function, and electrical characteristics.
What is the difference between 74HC541D and 74HC541D,653?
The difference is the ordering and packaging suffix. The ",653" suffix is a manufacturer-specific orderable part number code that typically denotes tape-and-reel packing and a specific reel quantity. The base part 74HC541D refers to the device type itself. Both refer to the same 74HC541 octal buffer in an SO package.
What package do the 74HC541D and 74HC541D,653 use?
Both use the SO (Small Outline) package, specifically a 20-pin SO20 / SOIC-20 wide-body package. The "D" suffix in the 74HC541D designation indicates the SO package option in the standard 74HC541 naming convention.
What is the operating voltage range of the 74HC541D and 74HC541D,653?
Both devices operate over a supply voltage range of 2.0 V to 6.0 V, consistent with the 74HC logic family. They are characterized for operation from -40 °C to +125 °C ambient temperature.
Can the 74HC541D and 74HC541D,653 be used interchangeably in a design?
Yes, from an electrical and functional standpoint they are the same device. The only practical difference is the ordering format and packing method. Designers should confirm the specific manufacturer's datasheet and the exact orderable part number required by their procurement or assembly process.
What is the output drive capability of the 74HC541D and 74HC541D,653?
Both devices provide standard 74HC output drive, typically ±6 mA at 4.5 V VCC, with 3-state outputs that can be placed in a high-impedance state via the output enable inputs. They are intended for bus-oriented and line-driving applications.
Do the 74HC541D and 74HC541D,653 have the same pinout?
Yes. Both use the standard 20-pin 74HC541 pinout with eight inputs, eight 3-state outputs, and two active-low output enable pins (OE1 and OE2). The pin configuration is identical because the package and die are the same.
Which manufacturers produce the 74HC541D and 74HC541D,653?
The 74HC541D and 74HC541D,653 are standard 74HC logic part numbers produced by multiple manufacturers, including Nexperia (formerly NXP Standard Products) and other licensed 74HC logic suppliers. The ",653" suffix is most commonly associated with Nexperia's ordering system. Always verify the specific manufacturer's datasheet for the exact orderable part number.
