Overview

The LC74FCT164245 and LC74FCT164245T 16-bit 3.3- to-5 V translators are fabricated in an advanced two-metal-layer CMOS technology. These high-speed low power transceivers are designed to be used as interfaces between 3.3 V and 5 V busses in 3.3/5 V dual power supply systems. The use of these products allows system designers to interface TTL-compatible 3.3 V components to 5 V components. The directionality and output enable control in these products is designed to allow them to be used as either two independent 8-bit transceivers or as a single 16-bit transceiver.
