SN74AVCH2T45DCTR – TEXAS INSTRUMENTS

The SN74AVCH2T45DCTR is a dual 4-bit, high-speed, 3-state octal buffer/line driver from Texas Instruments, belonging to the 74AVCH family. It features CMOS technology, offering low power consumption and high noise immunity. Each buffer section independently accepts four inputs and provides a corresponding four-bit output, capable of driving highly capacitive loads. The 3-state output enables bus sharing, allowing multiple devices to share a common bus. The device operates from a wide voltage range of 1.65V to 3.6V, making it suitable for various power supply designs. It’s packaged in a space-saving 20-pin TSSOP (Thin Shrink Small Outline Package)._x000D_

Its typical propagation delay is a mere 4.2ns (at 3V), highlighting its high-speed capabilities crucial for high-frequency applications. The low output impedance (≤ 12Ω) ensures reliable signal transmission even under heavy loading. Common applications include bus buffering in high-speed data acquisition systems, memory interfacing, and signal expansion in FPGA-based designs. The 74AVCH family’s advantages include superior speed and reduced power consumption compared to older TTL and CMOS logic families, making the SN74AVCH2T45DCTR a preferred choice where speed and power efficiency are paramount. Careful consideration should be given to its absolute maximum ratings to prevent component damage.
