SL74HCT138 1- of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The SL74HCT138 is identical in pinout to the LS/ALS138. The SL74HCT138 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The SL74HCT138 decodes a three-bit Address to one-of-eight active-lot outputs. This device features three Chip Selec.
three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chip-selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
ORDERING INFORMATION SL74HCT138N Plastic SL74HCT138D SOIC TA = -55° to 125° C for all pac.
