Product Summary
The TC74LCX541FT is a high-performance CMOS octal bus buffer. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply environment for both inputs and outputs. The TC74LCX541FT is a non-inverting 3-state buffer having two active-low output enables. When either OE1 orOE2 are high, the terminal outputs are in the high-impedance state. The TC74LCX541FT is designed to be used with 3-state memory address drivers, etc.
