IDT74ALVC162244
FEATURES:
• 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 (0.4µ W typ. static)
• Rail-to-Rail output swing for increased noise margin
• Available in SSOP, TSSOP, and TVSOP packages
DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
DESCRIPTION:
This 16-bit buffer/driver is built using advanced dual metal CMOS
technology. The ALVC162244 is designed specifically to improve 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. It provides
true outputs and symmetrical active-low output-enable (OE) inputs.
The ALVC162244 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.
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
