TC74ACT541FT Datasheet – Octal Bus Buffer IC
Non-Inverting Octal Bus Buffer
TC74ACT541FT overview
The TC74ACT541FT is a Non-Inverting Octal Bus Buffer made by Toshiba, supplied in these packages: DIP, SOP 20 Pin Type. The absolute maximum ratings table on this page lists the 9 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the TC74ACT541FT pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The TC74ACT540/TC74ACT541 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.
They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
These devices may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels.
The TC74ACT540 is an inverting type, and the TC74ACT541 is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
