IN74HC154A

TECHNICAL DATA IN74HC154A 1-of-16 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The IN74HC154A 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 IN74HC154A 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 IN74HC154AN Plastic IN74HC154ADW SOIC TA = -55° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT w w w .d e e h s a t a . u t4 m o c PIN 24 =VCC PIN 12 = GND 1 www.DataSheet4U.com IN74HC154A MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from C...
