Overview
CMOS Digital Integrated Circuits Silicon Monolithic TC74VCX244FT TC74VCX244FT 1.
Functional Description • Low-Voltage Octal Bus Buffer with 3.
6-V Tolerant Inputs and Outputs 2.
General The TC74VCX244FT 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.
