Low-Voltage Octal Bus Buffer with 5-V Tolerant Inputs and Outputs
The TC74LCX541 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 TC74LCX541 is a non-inverting 3-state buffer having two
active-low output enables. When either OE1 or OE2 are high,
the terminal outputs are in the high-impedance state. This device
is designed to be used with 3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static
discharge.
