Description

The 54HC154 is fabricated using a 2.5μm 5V CMOS
process and has the same high speed performance of
LSTTL combined with CMOS low power consumption. The
device consists of x4 active-high binary address inputs, x16
active-low outputs & x2 active-low chip-selects. The x2
active-low chip-selects can be used to strobe & eliminate
normal decoding ‘glitches’ on the outputs, or can be used to
expand the decoder. Both chip-selects must be low to
enable the outputs. The demultiplexing function is executed
by use of one chip-select input as multiplexed data input.
When the other chip-select input is low, the addressed
output will follow the state of the applied data.

Features:

 Output Drive Capability: 10 LSTTL Loads
 Low Input Current: 1μA
 Outputs directly interface CMOS, NMOS and TTL
 Operating Voltage Range: 2V to 6V
 CMOS High Noise Immunity
 Function compatible with 54LS154
 Full Military Temperature Range.
