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.
The ALVCH162344 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 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.

GENERAL DESCRIPTION
This low-voltage (1.7V to 3.7V) digital thermometer and thermostat provides 9, 10, 11, or 12-bit digital temperature readings over a -55°C to +125°C range with ±2°C accuracy over a -25°C to +100°C range. At power-up, the DS75LX defaults to 9-bit resolution for software compatibility with the LM75. Communication with the DS75LX is achieved through a simple 2-wire serial interface. Three tri-state address pins allow up to 27 DS75LX devices to operate on the same 2-wire bus, which greatly simplifies distributed temperature-sensing applications.
The DS75LX thermostat has a dedicated open-drain output (O.S.) and programmable fault tolerance, which allow the user to define the number of consecutive error conditions that must occur before O.S. is activated. There are two thermostatic operating modes that control thermostat operation based on user-defined trip-points (TOS and THYST).

APPLICATIONS
Any Thermally Sensitive System Cellular Base Stations
Telecom Switches and Routers Servers
