The SNJ54LS645J is an integrated circuit (IC) component that belongs to the family of 8-bit transceivers with tri-state outputs. This component is designed to provide bidirectional communication between two data buses, making it suitable for use in various applications such as data transfer between microprocessors, memory systems, and input/output (I/O) interfaces.
The key features of the SNJ54LS645J IC component are as follows:
1. Tri-state Outputs: This component offers eight tri-state outputs that can be enabled or disabled using the output enable (OE) input pin. When disabled, the outputs are in a high-impedance state, allowing multiple devices to be connected to the same bus without interference.
2. Bidirectional Data Transfer: The SNJ54LS645J facilitates bidirectional data transfer between two data buses, designated as Bus A and Bus B. It has two sets of 8-bit input/output (I/O) pins, one for each bus, allowing data to flow in either direction depending on the direction control (DIR) input pin.
3. Direction Control: The direction control (DIR) input pin determines the direction of data transfer. By toggling this pin's logic level, the IC can switch between transmitting data from Bus A to Bus B or vice versa. This flexibility enables the IC to be used as both a buffer and a transceiver
