No Preview Available ! TECHNICAL DATA 1-of-16 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS KK74HC154A The KK74HC154A is identical in pinout to the LS/ALS154. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device, when enabled, selects one of 16 active-low outputs. Two active-low Chip Selects are provided to facilitate the chip-select, demultiplexing, and cascading functions. When either Chip Select is high, all outputs are high. The demultiplexing function is accomplished by using the Address inputs to select the desired device output. The KK74HC154A is primarily used for memory address decoding and data routing applications. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION KK74HC154AN Plastic KK74HC154ADW SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT www.DataSheet4U.net PIN 24 =VCC PIN 12 = GND 1 1 page KK74HC154A Figure 1.
