74ACQ543SCX

The 74ACQ543SCX is an advanced high-speed octal registered transceiver integrated circuit (IC) component. It is specifically designed to provide efficient bidirectional communication between bus-oriented systems. This IC belongs to the 74AC series family, which ensures low power consumption alongside high-speed operation. One of the key features of the 74ACQ543SCX is its octal transceiver capability. It consists of two independent 8-bit registers that facilitate bidirectional data flow between two buses. Each register has separate outputs for sending data from one bus to the other while remaining transparent to the input data. This is particularly useful in scenarios where data needs to be exchanged between different bus systems without interference. Additionally, the 74ACQ543SCX has an output enable pin (OE) that allows the user to control the bus isolation and data flow. When OE is low, the IC is activated, and data can flow between the buses. Conversely, when OE is high, the IC enters a high-impedance state, preventing any data transfer, thereby isolating the buses. Another notable feature is the presence of 3-state outputs. This means that the IC's outputs can assume one of three possible states: low, high, or high impedance. This flexibility enables the IC to connect to multiple devices while efficiently managing bus collisions and ensuring data integrity
