1-of-16 Decoder/Demultiplexer
SEMICONDUCTOR TECHNICAL DATA-
High–Performance Silicon–Gate CMOSThe MC54/74HC154 is identical in pinout to the LS154. The device inputs
are compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
This device, when enabled, selects one of 16 active–low outputs. Two
active–low Chip Selects are provided to facilitate the chip–select, demulti-
plexing, 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. Then, while holding one
chip select input low, data can be applied to the other chip select input (see
Application Note).
The HC154 is primarily used for memory address decoding and data
routing applications. Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 μA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard
No. 7A Chip Complexity: 192 FETs or 48 Equivalent Gates
