IDT74ALVC164245
FEATURES:
• 0.5 MICRON CMOS Technology
• Typical tSK(o) (Output Skew) < 250ps
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCCA = 2.7V to 3.6V
• VCCB = 5V ± 0.5V
• CMOS power levels (0.4μ W typ. static)
• Rail-to-Rail output swing for increased noise margin
• Available in SSOP and TSSOP packages
DESCRIPTION:
This 16-bit 3.3V to 5V level shifting transceiver is manufactured using
advanced dual metal CMOS technology. The ALVC164245 contains two
separate supply rails; B port has VCCB, which is set at 5V, and A port has
VCCA, which is set to operate at 3.3V. This allows for translation from a 3.3V
to 5V environment and vice-versa. This device is designed for asynchro-
nous communication between data buses.
The ALVC164245 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
DRIVE FEATURES:
• High Output Drivers: ±24mA
• Suitable for heavy loads
APPLICATIONS:
• Mixed 3.3V and 5V High Speed Systems
• 5V PCI Interface to 3.3V PC Bus Structures
• Telecommunication Legacy Systems with transitions from 5V to
3.3V
