TC74VCX245FT

CMOS Digital Integrated Circuits Silicon Monolithic TC74VCX245FT TC74VCX245FT 1. Functional Description Low-Voltage Octal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs 2. General The TC74VCX245FT is a high performance CMOS octal bus transceiver which is guaranteed to operate from 1.2 V to 3.6 V. Designed for use in 1.5 V, 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 over voltage 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. All inputs are equipped with protection circuits against static discharge. 3.
