Make a strong finite state machine by implementing this 74HC154D,652 from NXP Semiconductors. This decoder has an operating temperature range of -40 °C to 125 °C. This product comes packaged in bulk, so the parts will be stored loosely. This inverting device has a typical operating supply voltage of 5 V. Its minimum operating supply voltage of 2 V, while its maximum is 6 V.
The 74HC154D,653 is a 4-to-16 line Decoder or Demultiplexer is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL ). The decoder accepts four active high binary address inputs and provide 16 mutually-exclusive active low outputs. The two-input enable gate can be used to strobe the decoder to eliminate the normal decoding glitches on the outputs or can be used for the expansion of the decoder. The enable gate has two ANDed inputs which must be low to enable the outputs. This can be used as a 1-to-16 demultiplexer by using one of the enable inputs as the multiplexed data input. When the other enable input is low, the addressed output will follow the state of the applied data.
The CD74HC154M is a 4-to-16 line Decoder/Demultiplexer IC with two enable inputs, E1 and E2. A high on either enable input forces the output into the high state. The demultiplexing function is performed by using the four input lines, A0 to A3, to select the output lines Y0/ to Y15/ and using one enable as the data input while holding the other enable low.
