DESCRIPTION:

ꢀ 0.5 MICRON CMOS Technology

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

compatible3.3Vcomponentswith5Vcomponents. Thedirectionandoutput

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; theBportinterfaceswiththe5Vbus. Thedirectioncontrol(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.

ꢀ Bidirectional interface between 3.3V and 5V buses

ꢀ Control inputs can be driven from either 3.3V or 5V circuits

ꢀ ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

ꢀ VCC1 = 5V 10%, VCC2 = 2.7V to 3.6V

ꢀ High drive outputs (-32mA IOH, 64mA IOL) on 5V port

ꢀ Power off disable on both ports permits “live insertion”

ꢀ Typical VOLP (Output Ground Bounce) < 0.9V at VCC1 = 5V,

VCC2 = 3.3V, TA = 25°C

ꢀ Available in SSOP and TSSOP packages

The FCT164245T is ideally suited for driving high-capacitance loads

and low-impedance backplanes. The output buffers are designed with

poweroffdisablecapabilitytoallow"hotinsertion"ofboardswhenusedas

backplane drivers. They also allow interface between a mixed supply

system and external 5 volt peripherals.
