CMOS Digital Integrated Circuits Silicon Monolithic TC74VCX164245 TC74VCX164245 1. Functional Description • 16-Bit Dual Supply Bus Transceiver 2. General The TC74VCX164245 is a dual supply, advanced high-speed CMOS 16-bit bus transceiver fabricated with silicon gate CMOS technology. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. Designed for use as an interface between a 3.3 V or 2.5 V bus and a 2.5 V or 1.8 V bus in mixed 3.3 V or 2.5 V/2.5 V or 1.8 V supply systems. The B-port interfaces with the 3.3 V or 2.5 V bus, the A-port with the 2.5 V or 1.8 V bus. The direction of data transmission is determined by the level of the DIR input. The enable input (OE) can be used to disable the device so that the buses are effectively isolated.
