The SY10/100E171 offer three 4:1 multiplexers with differential outputs, designed for use in new, highperformance ECL systems. The leading 4-bit multiplexer operation is organized pairwise, with each pair being a 2-bit multiplexer. Separate select (SEL_1A, SEL_1B) controls are provided within each pair. The SEL1A and SEL1B signals control the leading multiplexers, while the SEL2 signal controls the output multiplexer. The three select signals can be used to determine which of the four data inputs will be propagated to the corresponding outputs.

The LTC^®1874 is a dual constant frequency current mode step-down DC/DC controller with excellent AC and DC load and line regulation. Each controller has an accurate undervoltage lockout that shuts down the individual controller
when the input voltage falls below 2.0V.

The LTC1874 boasts ±2.5% output voltage accuracy and consumes only 270μA of quiescent current per controller. The LTC1874 is configured with Burst Mode operation, which enhances efficiency at low output current for applications where efficiency is a prime consideration.

To further maximize the life of a battery source, each external P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, each controller draws a mere 8μA. High constant operating frequency of 550kHz allows the use of small external inductors.

The LTC1874 is available in a small footprint 16-lead narrow SSOP.

The TCNT1000 have a compact construction where the emitting-light source and the detector are arranged in the same direction to sense the presence of an object by using the reflective IR-beam from the object.

The operating wavelength is 950 nm. The detector consists of a phototransistor.
