IDT74LVCC4245A CMOS OCTAL DUAL-SUPPLY TRANSCEIVER
CMOS OCTAL DUAL-SUPPLY IDT74LVCC4245A TRANSCEIVER WITH CONFIGURABLE OUTPUT VOLTAGE, 3-STATE OUTPUTS, 3.3V
FEATURES:
MICRON CMOS Technology VCCA 0.5V VCCB 2.7V 5.5V CMOS power levels (0.4µ typ. static) Rail-to-rail output swing increased noise margin inputs, outputs, tolerant Supports insertion Available SOIC, SSOP, QSOP, TSSOP packages
DESCRIPTION:
DRIVE FEATURES:
High Output Drivers: ±24mA Reduced system switching noise
LVCC4245A manufactured 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.
APPLICATIONS:
3.3V mixed voltage systems Data communication telecommunication systems
