3.3V CMOS 10-BIT FLIP-  
IDT74ALVCH162820  
FLOP WITH DUAL OUTPUTS  
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)  
This10-bitflip-flopisbuiltusingadvanceddualmetalCMOStechnology.  
The ALVCH162820 is an edge-triggered D-type flip-flop. On the positive  
transition of the clock (CLK) input, the device provides true data at the Q  
outputs.  
• VCC = 3.3V ± 0.3V, Normal Range  
• VCC = 2.7V to 3.6V, Extended Range  
• VCC = 2.5V ± 0.2V  
• CMOS power levels (0.4µ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
• Available in TSSOP package

lines significantly. The high-impedance state and increased drive provide  
the capability to drive bus lines without the need for interface or pullup  
components.OEinputdoesnotaffecttheinternaloperationoftheflip-flops.  
Old data can be retained or new data can be entered while the outputs are  
inthehigh-impedancestate.  
The ALVCH162820 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.  
DRIVE FEATURES:  
• Balanced Output Drivers: ±12mA  
• Low switching noise  
APPLICATIONS:  
• SDRAM Modules  
• PC Motherboards  
• Workstations  
The ALVCH162820 has “bus-hold” which retains the inputs’ last state  
whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs  
and eliminates the need for pull-up/down resistors.
