FAST CMOS 16-BIT  
BIDIRECTIONAL  
IDT74FCT164245T  
3.3V TO 5V TRANSLATOR  
FEATURES:  
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.
