TC74VCX244FT, TC74VCX244FK
Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs
The TC74VCX244 is a high performance CMOS octal bus
buffer which is guaranteed to operate from 1.2-V to 3.6-V.
Designed for use in 1.5V, 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 over voltage 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.
All inputs are equipped with protection circuits against static
discharge.
