IN74AC138規(guī)格書詳情
1-of-8 Decoder/Demultiplexer
High-Speed Silicon-Gate CMOS
The IN74AC138 is identical in pinout to the LS/ALS138, HC/HCT138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The IN74AC138 decodes a three-bit Address to one-of-eight active low outputs. This device features 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.
? Outputs Directly Interface to CMOS, NMOS, and TTL
? Operating Voltage Range: 2.0 to 6.0 V
? Low Input Current: 1.0 μA; 0.1 μA @ 25°C
? High Noise Immunity Characteristic of CMOS Devices
? Outputs Source/Sink 24 mA
