IDT74LVCC3245A CMOS OCTAL TRANSCEIVER WITH ADJUSTABLE OUTPUT
CMOS OCTAL IDT74LVCC3245A TRANSCEIVER WITH ADJUSTABLE OUTPUT VOLTAGE, 3-STATE OUTPUTS, VOLT TOLERANT
FEATURES:
MICRON CMOS Technology VCCA 2.3V 3.6V VCCB 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
DRIVE FEATURES:
High Output Drivers: ±24mA Reduced system switching noise
APPLICATIONS:
LVCC3245A manufactured 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.
