TC74VCX2244FT/FK

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74VCX2244FT, TC74VCX2244FK

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

TC74VCX2244FT

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-Ω

series resistor helps reducing output overshoot and undershoot

without external resistor.

TC74VCX2244FK

All inputs are equipped with protection circuits against static

discharge.
