IDT74LVC16244A 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVC16244A BUFFER/DRIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: The LVC16244A 16-bit buffer/driver is built using advanced dual metal Typical tSK(o) (Output Skew) < 250ps CMOS technology. The LVC16244A is designed specifically to improve ESD > 2000V per MIL-STD-883, Method 3015 > 200V using both the performance and density of 3-state memory address drivers, clock machine model (C = 200pF, R = 0) drivers, and bus-oriented receivers and transmitters. The device can be VCC = 3.3V 0.3V, Normal Range used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device VCC = 2.7V to 3.6V, Extended Range provides true outputs and symmetrical active-low output-enable (OE) CMOS power levels (0.4 W typ. static) inputs. All inputs, outputs, and I/O are 5V tolerant All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V Supports hot insertion devices. This feature allows the use of the device as a translator in a mixed Available in SSOP and TSSOP packages 3.3V/5V supply system. DRIVE FEATURES: The LVC16244A has been designed with a 24mA output driver. This High Output Drivers: 24mA driver is capable of driving a moderate to heavy load while maintaining Reduced system switching noise speed performance. APPLICATIONS: 5V and 3.3V mixed voltage systems Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1 25 1OE 3OE 47 2 36 13 1A1 3A1 1Y1 3Y1 46 3 35 14 1A2 1Y2 3A2 3Y2 44 33 5 16 1A3 3A3 1Y3 3Y3 43 6 32 17 1A4 1Y4 3A4 3Y4 48 24 2OE 4OE 8 30 19 41 2A1 4A1 2Y1 4Y1 29 20 40 9 2A2 2Y2 4A2 4Y2 11 27 22 38 2A3 4A3 2Y3 4Y3 12 23 37 26 2A4 2Y4 4A4 4Y4 IDT and the IDT logo is a registered trademark of Integrated Device Technology, Inc.
