Working Principles

The IDT74LVC244APYG8 is based on CMOS technology and operates as a buffer/line driver. It receives input signals on the "A" pins and transmits the corresponding output signals on the "Y" pins. The direction of data flow is controlled by the Output Enable (OE#) pin. When OE# is low, the outputs are enabled, allowing data transmission. When OE# is high, the outputs are disabled, effectively disconnecting the device from the bus.

Detailed Application Field Plans

The IDT74LVC244APYG8 is commonly used in various applications, including: - Data communication systems - Microprocessor/microcontroller interfacing - Memory address/data buses - Industrial control systems - Automotive electronics
