SN74AVC1T45DRLR – TEXAS INSTRUMENTS

The SN74AVC1T45DRLR is a Texas Instruments 3-state, single-supply, non-inverting octal buffer/line driver in a space-saving 20-pin, 4mm x 4mm, thin QFN (RHL) package. It operates from a single 1.65V to 3.6V supply voltage, offering robust performance across a wide input voltage range. Each of the eight independent buffers features a high-impedance, 3-state output, enabling bus sharing and system-level control. The device boasts a typical propagation delay of 4.5ns (VCC = 3.3V) and a maximum output current of ±24mA, making it suitable for high-speed applications requiring significant drive capability. Unlike its predecessors, the AVC series incorporates advanced CMOS technology, resulting in low power consumption and improved noise immunity._x000D_

Common applications include data bus buffering, memory interface expansion, and driving high-capacitance loads. The SN74AVC1T45DRLR’s advantages stem from its combination of speed, high drive strength, 3-state control, and compact QFN packaging, making it ideal for space-constrained, high-performance digital designs where reliable signal integrity is critical. Its wide operating voltage range ensures compatibility with various system architectures, simplifying design and reducing BOM complexity. The RHL package further enhances thermal performance compared to traditional SOIC packages.
