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 ±12mA 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.
