IDT74LVC162244A 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS AND 5 VOLT TOLERANT I/O IDT74LVC162244A DESCRIPTION: FEATURES: The LVC162244A 16-bit buffer/driver is built using advanced dual metal CMOS technology. The LVC162244A is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides true outputs and symmetrical active-low output-enable (OE) inputs. All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V devices. This feature allows the use of the device as a translator in a mixed 3.3V/5V supply system. The LVC162244A has series resistors in the device output structure which will significantly reduce line noise when used with light loads. This driver has been developed to drive ±12mA at the designated threshold levels. • 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 µ W typ. static) • CMOS power levels (0.4µ • All inputs, outputs, and I/O are 5V tolerant • Available in SSOP, TSSOP, and TVSOP packages DRIVE FEATURES: • Balanced Output Drivers: ±12mA • Low switching noise APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1OE 1 1A1 47 2 1A2 46 3 1A3 44 5 43 6 1A4 2OE 48 2A1 41 8 2A2 40 9 2A3 38 11 2A4 37 12 3OE 25 1Y1 3A1 36 13 3Y1 1Y2 3A2 35 14 3Y2 1Y3 3A3 33 16 1Y4 3A4 32 17 4OE 24 2Y1 4A1 30 19 2Y2 4A2 29 20 2Y3 4A3 27 22 2Y4 4A4 26 23 3Y3 3Y4 4Y1 4Y2 4Y3 4Y4 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
