High Speed CMOS Logic 4-to-16 Line Decoder/Demultiplexer with Input Latches
CD54HC4514, CD74HC4514, CD74HC4515 SCHS280C High-Speed CMOS Logic 4- to 16-Line November 1997 - Revised July 2003 Decoder/Demultiplexer with Input Latches Features Description • Multifunction Capability The CD54HC4514, CD74HC4514, and CD74HC4515 are high-speed silicon gate devices consisting of a 4-bit strobed - Binary to 1-of-16 Decoder [ /Title latch and a 4- to 16-line decoder. The selected output is - 1-to-16 Line Demultiplexer enabled by a low on the enable input (E). A high on E inhibits (CD74 • Fanout (Over Temperature Range) selection of any output. Demultiplexing is accomplished by HC451 using the E input as the data input and the select inputs (A0- - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads 4, A3) as addresses.
