SN75ALS1178NSR – TEXAS INSTRUMENTS

The SN75ALS1178NSR is a Texas Instruments quad bus transceiver featuring three-state outputs, specifically designed for high-speed, low-power applications. It operates from a single 4.5V to 5.5V supply voltage, exhibiting low propagation delays (typically 12ns) and enabling data rates exceeding 20Mbps. Each transceiver consists of two independent pairs of inverting drivers and receivers, facilitating bidirectional data transmission across a bus. The three-state control allows for easy bus sharing and efficient system control. Packaged in a space-saving 16-pin SOIC (Small Outline Integrated Circuit), it boasts low input current (typically 1mA) and output current (typically 24mA), minimizing power consumption. This component excels in applications requiring high-speed data transfer with minimal power dissipation, such as industrial control systems, peripheral interfacing, and high-speed data acquisition systems where bus contention is a concern. Its low propagation delay and three-state capability significantly improve system performance and simplify bus management compared to simpler transceivers. The ALS technology offers a balance between speed and power consumption, making it a versatile solution for a range of applications.
