IDT74ALVCHS162830 3.3V CMOS 1-BIT TO 2-BIT ADDRESS DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 1-BIT TO 2-BIT ADDRESS DRIVER WITH 3-STATE OUTPUTS AND BUS-HOLD * 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 * CMOS power levels (0.4 W typ. static) * Rail-to-Rail output swing for increased noise margin * Available in TVSOP package IDT74ALVCHS162830 FEATURES: DESCRIPTION: This 1-bit to 2-bit address driver is built using advanced dual metal CMOS technology. Diodes to VCC have been added on the inputs to clamp overshoot. The ALVCHS162830 has series resistors in the device output structure which will significantly reduce line noise when used with light loads. This driver has been designed to drive 12mA at the designated threshold levels. The ALVCHS162830 has "bus-hold" which retains the inputs' last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. DRIVE FEATURES: * Balanced Output Drivers: 12mA * Low switching noise APPLICATIONS: * SDRAM Modules * PC Motherboards * Workstations FUNCTIONAL BLOCK DIAGRAM VCC OE2 21 VCC OE1 20 VCC A1 7 5 1Y 1 4 2Y1 TO 17 OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
