IDT74LVCH162244A 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE IDT74LVCH162244A 3.3V CMOS 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O, AND BUS-HOLD Features : - Typical t SK(o) (Output Skew) < 250ps - ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200p F, R = 0) - VCC = 3.3V ± 0.3V, Normal Range - VCC = 2.7V to 3.6V, Extended Range - CMOS power levels (0.4μ W typ. static) .. - All inputs, outputs, and I/O are 5V tolerant - Available in SSOP and TSSOP packages DESCRIPTION: The LVCH162244A 16-bit buffer/driver is built using advanced dual metal CMOS technology. The LVCH162244A 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 this device as a translator in a mixed 3.3V/5V supply system. The LVCH162244A 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 ±12m A at the designated threshold levels. The LVCH162244A has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. DRIVE Features : - Balanced Output Drivers: ±12m A - Full internal series termination APPLICATIONS: - 5V and 3.3V mixed voltage systems - Data munication and telemunication systems FUNCTIONAL BLOCK DIAGRAM 1OE 1 3OE 25 1A1 1Y1 3A1 3Y1 1A2 1Y2 3A2...
