IDT74ALVC164245 16-BIT 3.3V TO 5V LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE CMOS 16-BIT 3.3V IDT74ALVC164245 TO 5V LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS DESCRIPTION: FEATURES: This 16-bit 3.3V to 5V level shifting transceiver is manufactured using 0.5 MICRON CMOS Technology advanced dual metal CMOS technology. The ALVC164245 contains two Typical tSK(o) (Output Skew) < 250ps separate supply rails B port has VCCB, which is set at 5V, and A port has ESD > 2000V per MIL-STD-883, Method 3015 > 200V using VCCA, which is set to operate at 3.3V. This allows for translation from a 3.3V machine model (C = 200pF, R = 0) to 5V environment and vice-versa. This device is designed for asynchro- VCCA = 2.7V to 3.6V nous communication between data buses. VCCB = 5V 0.5V The ALVC164245 has been designed with a 24mA output driver. This CMOS power levels (0.4 W typ. static) driver is capable of driving a moderate to heavy load while maintaining Rail-to-Rail output swing for increased noise margin speed performance. Available in SSOP and TSSOP packages DRIVE FEATURES: APPLICATIONS: High Output Drivers: 24mA Mixed 3.3V and 5V High Speed Systems Suitable for heavy loads 5V PCI Interface to 3.3V PC Bus Structures Telecommunication Legacy Systems with transitions from 5V to 3.3V FUNCTIONAL BLOCK DIAGRAM 1 24 1DIR 2DIR 48 25 2OE 1OE 47 36 1A1 2A1 2 13 1B1 2B1 46 35 1A2 2A2 3 14 1B2 2B2 44 33 1A3 2A3 5 16 1B3 2B3 43 32 1A4 2A4 6 17 1B4 2B4 41 30 1A5 2A5 8 19 1B5 2B5 40 29 1A6 2A6 9 20 1B6 2B6 38 27 1A7 2A7 11 22 1B7 2B7 37 26 1A8 2A8 12 23 1B8 2B8 IDT and the IDT logo is a registered trademark of Integrated Device Technology, Inc.
