IDT74LVCC3245A CMOS OCTAL BUS TRANSCEIVER WITH ADJUSTABLE OUTPUT INDUSTRIAL TEMPERATURE RANGE CMOS OCTAL BUS IDT74LVCC3245A TRANSCEIVER WITH ADJUSTABLE OUTPUT VOLTAGE, 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: • • • • • • • • The LVCC3245A is manufactured using advanced dual metal CMOS technology. This 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track VCCB, which accepts voltages from 3V to 5.5V, and the A port is designed to track VCCA, which operates at 2.3V to 3.6V. This allows for translation from a 3.3V to a 5V system environment and vice-versa, or from a 2.5V to a 3.3V system environment, and vice-versa. This LVCC3245A is ideal for asynchronous communication between two 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) input can be used to disable the device so the buses are effectively isolated. The LVCC3245A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. 0.5 MICRON CMOS Technology VCCA = 2.3V to 3.6V VCCB = 3V to 5.5V µ W typ. static) CMOS power levels (0.4µ 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 DRIVE FEATURES: • High Output Drivers: ±24mA • Reduced system switching noise APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 2 22 A1 21 A2 B6 9 2.3V to 3.6V Port 15 A8 B5 8 16 A7 B4 7 17 A6 B3 6 18 A5 B2 5 19 A4 B1 4 20 A3 OE 3 3V to 5.5V Port DIR B7 10 14 B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
