DESCRIPTION:
The FCT164245T 16-bit 3.3V-to-5V translator is built using advanced
dual metal CMOS technology. This high-speed, 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 pin (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 5 volt peripherals.
