Performance and Applications

The SN74LS244NE4 is engineered to deliver high-speed performance while maintaining the integrity of the signal it is driving. With a propagation delay time of just 10ns at 5V, it is an excellent choice for systems that require quick response times. The device's octal configuration allows it to drive eight separate lines, making it a versatile component for bus-oriented systems.

With its 3-state outputs, the SN74LS244NE4 can be used in bus-organized systems without the need for external pull-up resistors, simplifying design and reducing component count. This feature also allows for direct connection to a bus, enabling the outputs to be disabled and effectively removed from the bus during standby or other inactive conditions.

The device is widely used in a variety of applications such as memory address drivers, bus-oriented receivers and transmitters, and input/output port drivers. Its robust design ensures that it is suitable for demanding environments, and its standard PDIP-20 packaging makes it compatible with a broad range of existing circuit board layouts.
