DESCRIPTION:
This 16-bit buffer/driver is built using advanced dual metal CMOS
technology. The ALVCH162244 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 ALVCH162244 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 ALVCH162244 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.
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
