1 / 8 page INDUSTRIALTEMPERATURERANGE IDT74LVC4245A CMOS OCTAL BUS TRANSCEIVER AND 3.3V TO 5V SHIFTER 1 JULY 2000 INDUSTRIAL TEMPERATURE RANGE The IDT logo is a registered trademark of Integrated Device Technology, Inc. © 2000 Integrated Device Technology, Inc. DSC-4754/1 FEATURES: • 0.5 MICRON CMOS Technology •VCCA = 5V ± 0.5V •VCCB = 2.7V to 3.6V • CMOS power levels (0.4 µµµµµ 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 SOIC, SSOP, QSOP, and TSSOP packages FUNCTIONAL BLOCK DIAGRAM APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems DRIVE FEATURES: • High Output Drivers: ±24mA • Reduced system switching noise IDT74LVC4245A DESCRIPTION: The LVC4245A is manufactured using advanced dual metal CMOS technology. This octal noninverting bus transceiver contains two separate supply rails; B port has VCCB, which is set at 3.3V, and A port has VCCA, which is set at 5V. This allows for translation from a 3.3V to a 5V environment, and vice-versa. This device is ideal for asynchronous communication between two buses (A and B). The direction control pin (DIR) controls the direction of data flow. The output enable pin (OE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. The LVC4245A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance.
