Functional Features

SN74LS640NG4 is an octal bus transceiver with non-inverting 3-state outputs. It allows bidirectional data transfer between two independent buses, A and B. The direction of data flow is controlled by the Output Enable (OE) pin. When OE is low, data from bus A is transferred to bus B, and vice versa.

The IC features a high-speed operation, making it suitable for applications requiring quick data transfer. It also provides compatibility with other TTL devices, ensuring seamless integration into existing systems.

Advantages and Disadvantages
