TC74VCX16244FT
TC74VCX16244FT is Low-Voltage 16-Bit Bus Buffer manufactured by Toshiba.
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
Low-Voltage 16-Bit Bus Buffer with 3.6-V Tolerant Inputs and Outputs
The TC74VCX16244FT is a high-performance CMOS 16-bit 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. It can be used as four 4-bit buffers or two 8-bit buffers or one 16-bit buffer. 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.
Weight: 0.25 g (typ.)
