The MC623 3.0V dual trip point temperature sensor is a 3.0V solid-state, programmable temperature sensor designed for use in thermal management applications. It features dual thermal interrupt outputs (LOW LIMIT and HIGH LIMIT) each of which program with a single external resistor. When measured temperature exceeds the user-programmed limits, the HIGH LIMIT and LOW LIMIT outputs are driven active (high). When temperature exceeds the HIGH LIMIT setpoint, the CONTROL output is driven active (high), and turned off when temperature falls below the LOW LIMIT setpoint. The CONTROL output can be used to provide simple ON/OFF control to a cooling fan if so desired. Low voltage operation, easy setpoint programming, small size and low cost make the MC623 an ideal choice for many thermal management applications.

The MC642 is a pulse width modulation (PWM) fan speed controller for use with DC motors. It provides temperature proportional speed control. A thermistor connected to the VIN input furnishes the required control voltage of 1.25V to 2.65V for 0% to 100% PWM duty cycle. Minimum fan speed is set by a simple resistor divider on the VMIN input. An integrated Start–Up Timer ensures reliable motor start–up at turn–on, coming out of Shutdown Mode, or following a transient fault. A stalled, open, or unconnected fan causes the MC642 to trigger its start–up timer once. If the fault persists, the FAULT output goes low, and the device is latched in Shutdown Mode. Features include: Shutdown Mode for Power Saving, Supports Low Cost NTC/PTC Thermistors, Temperature Proportional Speed for Acoustic Control / Longer Fan Life, Fan Voltage Independent of MC642 Supply Voltage, Fault Detection Circuits Protect Against Fan Failure and Aid System Testing, Operating Temperature Range: 0°C to +85°C. Typical applications: Power Supplies, Personal Computers, UPS’s, Power Amplifiers, etc.

The bipolar LSI MC68194 Carrier Band Modem (CBM) when combined with the MC68824 Token Bus Controller provides an IEEE 802.4 single channel, phase–coherent carrier band Local Area Network (LAN) connection. The CBM performs the Physical Layer function including symbol encoding/decoding, signal transmission and reception, and physical management.

The MC14043B and MC14044B quad R-S latches are constructed with MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. Each latch has an independent Q output and set and reset inputs. The Q outputs are gated through three-state buffers having a common enable input. The outputs are enabled with a logical “1” or high on the enable input; a logical “0” or low disconnects the latch from the Q outputs, resulting in an open circuit at the Q outputs.

The MC10/100EP32 is an integrated ÷2 divider with differential CLK inputs. It has a typical propagation delay of 350 ps and a maximum frequency greater than 4 GHz. It can operate in a voltage range of 3.0 V to 5.5 V and features open input default state and safety input clamp.

The CS1112 is a Power Output Driver. The IC incorporates four protected DMOS low–side drivers designed to drive inductive and resistive loads in an automotive environment. The outputs are controlled by an 8–bit serial peripheral interface (SPI) or its associated parallel input. Each output contains overcurrent protection, open load detection, and inductive flyback clamps. The device is overvoltage protected. Overcurrent and open load faults are reported over the SPI port, and at the STATUS lead.
