Product Introduction

Overview

The SN74HCT541N is an octal buffer and line driver integrated circuit produced by Texas Instruments. This device is designed to offer high performance similar to the popular ’HC240 series, with a convenient pinout that places inputs and outputs on opposite sides of the package. This arrangement significantly simplifies printed circuit board (PCB) layout. The SN74HCT541N is part of the HCT (High-Speed CMOS) family, which is compatible with TTL (Transistor-Transistor Logic) voltage levels, making it versatile for various digital circuit applications.
