Author: Tanssion Date: 2023-05-24 Hits: 121

The part number SN74S85N corresponds to a specific integrated circuit (IC) manufactured by Texas Instruments. Here are the details for the SN74S85N:

SN74S85N

1.SN: This prefix indicates that the part is a standard TTL (Transistor-Transistor Logic) device manufactured by Texas Instruments.


2.74: This identifies the part as a member of the 74 series, which is a widely used family of logic ICs.


3.S: The "S" in the part number indicates that the IC is built using Schottky TTL technology. Schottky TTL offers faster switching speeds and lower power consumption compared to standard TTL.


4.85: This number identifies the specific function of the IC. In this case, the SN74S85N is a 4-bit magnitude comparator.


5.N: The "N" suffix indicates the package type. In this case, "N" stands for DIP (Dual Inline Package), which is a through-hole package with pins that can be soldered onto a circuit board.


Please note that the SN74S85N is an older part and may have been superseded or discontinued. For accurate and up-to-date information, it is recommended to refer to the datasheet provided by Texas Instruments or contact their customer support for specific details about the SN74S85N, including its electrical characteristics, pin configuration, and other relevant parameters.


The SN74S85N is a specific part number for an integrated circuit (IC) manufactured by Texas Instruments. Here are some general parameters typically associated with the SN74S85N:


1.Logic Family: The SN74S85N belongs to the S (Schottky) series of TTL (Transistor-Transistor Logic) ICs. Schottky TTL offers fast switching speed and low power consumption.


2.Functionality: The SN74S85N is a 4-bit magnitude comparator. It compares two 4-bit binary numbers and determines their relationship (greater than, less than, or equal).


3.Supply Voltage Range: The SN74S85N typically operates at a supply voltage (VCC) ranging from 4.5V to 5.5V.


4.Operating Temperature Range: The SN74S85N is designed to operate within a specified temperature range, typically from 0°C to +70°C or wider, depending on the specific variant.


5.Package Type: The "N" suffix in the part number indicates the package type. In this case, "N" refers to a DIP (Dual Inline Package) package, which has through-hole pins for mounting on a circuit board.


6.Input Pins: The IC has two sets of 4-bit input pins, labeled A1-A4 and B1-B4, which are used to input the binary numbers to be compared.


7.Output Pins: The SN74S85N has three output pins, labeled A<B, A=B, and A>B, which indicate the comparison result. The outputs are active-low, meaning they are low (logic 0) when the corresponding condition is true.


8.Supply Voltage Range: The SN74S85N typically operates with a supply voltage (VCC) ranging from 4.75V to 5.25V.


Please note that the specific electrical characteristics, pin configuration, and other detailed information can be found in the datasheet provided by Texas Instruments for the SN74S85N. The datasheet will provide comprehensive information about the IC, including its electrical specifications, pin configurations, timing characteristics, and other relevant details.
