Low-Voltage Octal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs
The TC74VCXR2245 is a high-performance CMOS octal bus
transceiver. 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.
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.
