TECHNICAL DATA www.DataSheet4U.com KK74ACT138 1-of-8 Decoder/Demultiplexer High-Speed Silicon-Gate CMOS The KK74ACT138 is identical in pinout to the LS/ALS138, HC/HCT138. The KK74ACT138 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74ACT138 decodes a three-bit Address to one-of-eight activelot output.
three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chipselecting 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; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
