IDT74ALVC16245 3.3V CMOS 16-BIT BUS TRANSCIEVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS IDT74ALVC16245 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) • VCC = 3.3V ± 0.3V, Normal Range • VCC = 2.7V to 3.6V, Extended Range • VCC = 2.5V ± 0.2V μ W typ. static) • CMOS power levels (0.4μ • Rail-to-Rail output swing for increased noise margin • Available in TSSOP package This 16-bit bus transceiver is built using advanced dual metal CMOS technology. The ALVC16245 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. The ALVC16245 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 • 3.3V high speed systems • 3.3V and lower voltage computing systems FUNCTIONAL BLOCK DIAGRAM 1DIR 1 2DIR 48 1A1 1 A2 2A1 2A2 2A3 5 1A4 2A4 6 1A5 1A6 1A7 1A8 2A6 2B3 2A7 2A8 1 B8 19 2B5 20 2B6 22 2B7 23 2B8 27 1B7 37 2B4 29 1B6 38 12 16 30 1B5 40 11 2B2 17 2A5 9 14 32 1B4 41 8 2B1 33 1B3 43 13 35 1B2 44 2OE 36 1B1 46 3 1A3 25 1OE 47 2 24 26 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
