Low-Voltage Octal Bus Buffer with 3.6-V Tolerant Inputs and Outputs
The TC74VCX2244 is a high-performance CMOS octal bus
buffer. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it
achieves high-speed operation while maintaining the CMOS low
power dissipation.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
This device is non-inverting 3-state buffer having four
active-low output enables. When the OE input is high, the
outputs are in a high-impedance state. This device is designed to
be used with 3-state memory address drivers, etc. The 26-â¦
series resistor helps reducing output overshoot and undershoot
without external resistor.
All inputs are equipped with protection circuits against static
discharge.
