74HC139 (Dual 2 to 4 Line Decoder) IR Reflective A 3-wire interface is used

A 3-wire interface is used for all communications with a microcontroller

The module output is normally LOW and outputs a series of random HIGH pulses when a vibration or shock is detected

Humidity Range: 0% to 100%

Data Transfer for Read or Write of Clock or RAM Data

Material: Plastic + Metal

74HC139 (Dual 2 to 4 Line Decoder) IR Reflective A 3-wire interface is usedIntroduction : 74HC139 decodes two binary weighted address inputs (nA0, nA1) to four mutuallyexclusive outputs (nY0 to nY3). Each decoder features an enable input (nE). When nE is HIGH alloutputs are forced HIGH. The enable input can be used as the data input for a 1 to 4 demultiplexerapplication. Inputs include clamp diodes. This enables the use of current limiting resistors tointerface inputs to voltages in excess of VCC. Features : Propagation
