TC74VCX244FK Datasheet | Toshiba

Description - Low-Voltage Octal Bus Buffer with 3.6-V Tolerant Inputs and Outputs 2. General The TC74VCX244FK 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 1.5 V, 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 two 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. 3.
