IDT74ALVC16245 3.3V CMOS 16-BIT BUS TRANSCIEVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74ALVC16245 BUS TRANSCEIVER WITH 3-STATE OUTPUTS DESCRIPTION: FEATURES: This 16-bit bus transceiver is built using advanced dual metal CMOS 0.5 MICRON CMOS Technology technology. The ALVC16245 is designed for asynchronous communication Typical tSK(o) (Output Skew) < 250ps between data buses. The control-function implementation minimizes external ESD > 2000V per MIL-STD-883, Method 3015 > 200V using timing requirements. machine model (C = 200pF, R = 0) This device can be used as two 8-bit transceivers or one 16-bit transceiver. VCC = 3.3V 0.3V, Normal Range It allows data transmission from the A bus to the B bus or from the B bus to the VCC = 2.7V to 3.6V, Extended Range A bus, depending on the logic level at the direction-control (DIR) input. The VCC = 2.5V 0.2V output-enable (OE) input can be used to disable the device so that the buses CMOS power levels (0.4 W typ. static) are effectively isolated. Rail-to-Rail output swing for increased noise margin The ALVC16245 has been designed with a 24mA output driver. This driver Available in TSSOP package is capable of driving a moderate to heavy load while maintaining speed performance.
