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, TSSOP, and TVSOP 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 1 2 DIR 24 48 25 2 OE 1 OE 1A 1 47 2A1 2 13 1B 1 46 2A 2 1A 2 3 2A 3 16 43 6 1B 4 1A 5 41 8 1A6 1A 7 2A 4 17 2A5 20 2A 7 22 1B7 1A 8 2A 8 12 2B 7 26 23 1B 8 2B 6 27 11 37 2B 5 29 1B6 38 2B4 30 19 2A 6 2B 3 32 1B 5 40 9 2B 2 33 1B 3 5V Port 3.3V Port 5 1A 4 14 44 2B 1 35 1B 2 3.3V Port 1A 3 36 5V Port 1 DIR 2B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
