Working Principles

The SN74ALVCH16244DLR is a 16-bit bus transceiver that allows bidirectional data transfer between two ports, A and B. The direction of data flow is controlled by the output enable pins (OE1 and OE2). When OE1 is low, data can be transmitted from port A to port B, and when OE2 is low, data can be transmitted from port B to port A.

The IC operates at a supply voltage range of 1.65V to 3.6V, making it suitable for low-voltage applications. It has a high output drive strength of ±24mA, enabling it to drive capacitive loads and long traces without signal degradation. The propagation delay is minimal, ensuring fast data transmission.
