IDT74LVCC4245A 3.3V CMOS OCTAL DUAL-SUPPLY TRANSCEIVER
3.3V CMOS OCTAL DUALIDT74LVCC4245A SUPPLY TRANSCEIVER WITH ADVANCE CONFIGURABLE OUTPUT VOLTAGE, INFORMATION 3-STATE OUTPUTS, VOLT
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 Drive Features LVCC4245A: High Output Drivers: ±24mA Reduced system switching noise
DESCRIPTION:
LVCC4245A built using advanced dual metal CMOS technology. This 8-bit (octal) noninverting transceiver contains separate power-supply rails. configurable port designed track VCCB, which accepts voltages from port dedicated accept supply level. This allows translation from 3.3V system environment vice-versa. This LVCC4245A 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. LVCC4245A been designed with ±24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance.
