FUNCTIONAL BLOCK DIAGRAM

DESCRIPTION:

This 1-bit to 4-bit address driver is built using advanced dual metal CMOS

technology. The ALVCH162344 device is used in applications in which four

separate memory locations must be addressed by a single address.

TheALVCH162344hasseriesresistorsinthedeviceoutputstructurewhich

will significantly reduce line noise when used with light loads. This driver has

been designed to drive ±12mA at the designated threshold levels.

The ALVCH162344 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.

DRIVE FEATURES:

• Balanced Output Drivers: ±12mA

• Low switching noise
