IDT74ALVC164245 16-BIT 3.3V TO 5V LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS CMOS 16-BIT 3.3V TO 5V LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE IDT74ALVC164245 FEATURES: DESCRIPTION: • 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 μ W typ. static) • CMOS power levels (0.4μ • Rail-to-Rail output swing for increased noise margin • Available in SSOP and TSSOP packages 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. DRIVE FEATURES: APPLICATIONS: • High Output Drivers: ±24mA • Suitable for heavy loads • 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 FUNCTIONAL BLOCK DIAGRAM 2DIR 48 47 2A1 2 1A2 2A2 3.3V Port 2A3 5 1A4 43 6 1A5 2A4 2A6 2A8 12 1B8 16 2B3 2B4 30 19 2B5 20 2B6 22 2B7 23 2B8 29 27 1B7 1A8 37 2B2 32 1B6 2A7 11 14 33 1B5 38 2B1 17 2A5 40 9 1A7 1B4 41 8 1A6 1B3 13 35 1B2 44 2OE 36 1B1 46 3 1A3 25 1OE 3.3V Port 1A1 24 5V Port 1 5V Port 1DIR 26 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
