CMOS OCTAL DUAL-SUPPLY  
BUS TRANSCEIVER WITH  
IDT74LVCC4245A  
CONFIGURABLE OUTPUT VOLTAGE,  
3-STATE OUTPUTS, 3.3V AND 5V I/O  
FEATURES:  
DESCRIPTION:  
• 0.5 MICRON CMOS Technology  
• VCCA = 5V ± 0.5V  
The LVCC4245A is manufactured using advanced dual metal CMOS  
technology. This 8-bit (octal) noninverting bus transceiver contains two  
separate power-supply rails. The configurable B port is designed to track  
VCCB, which accepts voltages from 3V to 5V, and the A port is dedicated to  
accept a 5V supply level. This allows for translation from a 3.3V to a 5V  
system environment and vice-versa.  
ThisLVCC4245Aisidealforasynchronouscommunicationbetweentwo  
data buses (A and B). The device transmits data from A to B or from B to  
A, depending on the logic level at the direction-control (DIR) input. The  
output-enable(OE)inputcanbeusedtodisablethedevicesothebusesare  
effectivelyisolated.  
• VCCB = 2.7V to 5.5V  
• CMOS power levels (0.4µ W typ. static)  
• Rail-to-rail output swing for increased noise margin  
• All inputs, outputs, and I/O are 5V tolerant  
• Supports hot insertion  
• Available in SSOP, QSOP, and TSSOP packages  
DRIVE FEATURES:  
• High Output Drivers: ±24mA  
• Reduced system switching noise  
The LVCC4245A has been designed with a ±24mA output driver. This  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems
