The TC74VCXR162245FT is a high-performance CMOS 16-bit bus transceiver produced by Toshiba Corporation. This transceiver is designed for use in 1.8-V, 2.5-V or 3.3-V systems, while maintaining CMOS low power dissipation and achieving high-speed operation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. This 16 bit bus transceiver is controlled by direction control (DIR) inputs and output enable (OE) inputs which are common to each byte. It can be used as two 8-bit transceivers or one 16-bit transceiver. The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable the device so that the busses are effectively isolated. The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge.
