Product Summary

The TC74LCX245FT is a TSHIBA CMOS digital intergrated circuit. It is low-voltage octal bus transceiver with 5-V tolerant inputs and outputs. The TC74LCX245FT is a high-performance CMOS octal bus transceiver. Designed for use in 3.3V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The TC74LCX245FT is designed for low-voltage VCC applications, but it could be used to interface to 5V supply environment for both inputs and outputs. All inputs are equipped with protection circuits against static discharge.
