SN75452BD – TEXAS INSTRUMENTS

The Texas Instruments SN75452BD is a quad, high-speed, 3-state, bus-transceiver in a space-saving 16-pin SOIC package. It features independent enable pins for each pair of transceivers, allowing for flexible bus control and signal routing. Operating from a single 3V to 5.5V supply, it boasts a typical propagation delay of 7ns (at 5V), making it suitable for high-speed data transmission applications. The 3-state output allows for efficient bus sharing and simplifies system design. Each transceiver offers a high-impedance off-state, minimizing power consumption during inactive periods. The device’s common-mode input voltage range extends from -0.5V to VCC + 0.5V, providing robust noise immunity. Typical applications include connecting microprocessors to peripherals, implementing data bus expansion, and constructing high-speed communication interfaces within industrial control systems or high-performance computing architectures. Its low propagation delay and independent enable functionality offer advantages over simpler transceivers by reducing latency and enhancing system flexibility, particularly in designs requiring precise timing control and efficient bus management. The SOIC package ensures compact board-level integration.
