SN74HCT541N – TEXAS INSTRUMENTS

The SN74HCT541N is a high-speed CMOS quad bus buffer/line driver featuring three-state outputs, optimized for interfacing between high-impedance and low-impedance systems. It operates from a single 2-5.5V supply voltage, exhibiting a typical propagation delay of 7ns (V_CC = 5V) and a maximum clock-to-output delay of 8ns under the same conditions. Each of the four independent buffers provides a high-current drive capability, typically sourcing or sinking 24mA, making it suitable for driving relatively capacitive loads. Packaged in a space-saving 14-pin plastic DIP, the device features a low input current (typically 1µA) and boasts a wide operating temperature range of -40°C to +85°C._x000D_

Its three-state outputs allow for easy bus sharing and multiplexing, making it ideal for applications requiring data bus control, memory expansion, and peripheral interfacing in systems with multiple data sources. The SN74HCT541N’s high speed and robust drive capability are advantageous in high-frequency digital systems where fast signal transmission and reliable data integrity are critical. Its CMOS technology ensures low power consumption compared to its TTL counterparts, making it suitable for battery-powered or power-sensitive applications. The wide operating voltage range also offers design flexibility across various power supply standards.
