IDT74FCT164245T General Description
The FCT164245T 16-bit 3.3V-to-5V translator is built using advanced dual metal CMOS technology. This highspeed, low-power transceiver 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 A port interfaces with the 3.3V bus; the B port interfaces with the 5V bus. The direction control (xDIR) pin controls the direction of data flow. The output enable (xOE) overrides the direction control and disables both ports. These control signals can be driven from either 3.3V or 5V devices.
The FCT164245T is ideally suited for driving high capacitance loads and low impedance backplanes. The output buffers are designed with Power-Off Disable capability to allow "hot insertion" of boards when used as backplane drivers. They also allow interface between a mixed supply system and external 5V peripherals.
