IDT74ALVC164245 ADVANCE INFORMATION
DESCRIPTION:
0.5 MICRON CMOS Technology Typical tSK(0) (Output Skew) < 250ps ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) 0.635mm pitch SSOP, 0.50mm pitch TSSOP, and 0.40mm pitch TVSOP packages Extended commercial range of – 40°C to + 85°C 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
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 asynchronous 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.
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
Drive Features for ALVC164245: – High Output Drivers: ±24mA – Suitable for heavy loads
