Part Number: 74LS140
Function: LSTTL Dual 4-input NAND
Package: DIP 14 Pin Type
Manufacturer: TW, BDTIC
The 74LS140 is 4-input NAND gates, 50-Ohm line drivers.
In computer science, NAND is a logic gate that produces a logical “NOT-AND” output from two logical inputs. In addition to being a fundamental building block of digital circuits, NAND gates are also used to construct other logic gates, such as OR and NOT gates.
Typical parameters: tpd = 12ns Pd = 4.3mW
