IDT74LVCC3245A 3.3V CMOS OCTAL TRANSCEIVER WITH ADJUSTABLE OUTPUT
3.3V CMOS OCTAL IDT74LVCC3245A TRANSCEIVER WITH ADJUSTABLE ADVANCE OUTPUT VOLTAGE, 3-STATE OUTINFORMATION PUTS, VOLT TOLERANT
MICRON CMOS Technology 2000V MIL-STD-883, Method 3015; 200V using machine model 200pF, 1.27mm pitch SOIC, 0.65mm pitch SSOP, 0.635mm pitch QSOP, 0.65mm pitch TSSOP packages Extended commercial range 40°C +85°C 3.3V ±0.3V, Normal Range 2.3V 3.6V, Extended Range CMOS power levels (0.4µ typ. static) Rail-to-Rail output swing increased noise margin inputs, outputs Volt tolerant Supports insertion
DESCRIPTION:
LVCC3245A built using advanced dual metal CMOS technology. This 8-bit (octal) noninverting transceiver contains separate supply rails. port designed track VCCB, which accepts voltages from 5.5V, port designed track VCCA, which operates 2.3V 3.6V. This allows translation from 3.3V system environment vice-versa, from 2.5V 3.3V system environment, vice-versa. This LVCC3245A ideal asynchronous communication between data buses device transmits data from from depending logic level direction-control (DIR) input. output-enable (OE) input used disable device buses effectively isolated. LVCC3245A been designed with ±24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance.
Drive Features LVCC3245A: High Output Drivers: ±24mA Reduced system switching noise
