Overview
TC74VCX16646FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16646FT Low-Voltage 16-Bit Bus Transceiver/Register with 3.
6-V Tolerant Inputs and Outputs The TC74VCX16646FT is a high-performance CMOS 16-bit bus transceiver/register.
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 bus transceiver with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers.
All inputs are equipped with protection circuits against static discharge.

3 V signals.
• 3.
6-V tolerant function and power-down protection provided on all inputs and outputs Note: Do not apply a signal to any bus pins when it is in the output mode.
Damage may result.
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down resistors.
