74FCT164245T - Block Diagram
Description
The 74FCT164245T 16-bit high-speed, low-power 3.3V to 5V translator is designed to interface between a 3.3V bus and a 5V bus in a mixed 3.3V/5V supply environment. This enables system designers to interface TTL-compatible 3.3V components with 5V components. The Direction and Output Enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The 74FCT164245T is ideally suited for driving high-capacitance loads and low-impedance backplanes. The 74FCT164245T operates at -40 °C to +85 °C.
