description
The ’FCT138T devices are 1-of-8 decoders. These devices accept three binary weighted inputs (A
0
, A
1
, A
2
)
and, when enabled, provide eight mutually exclusive active-low outputs (O
0
–O
7
). The ’FCT138T devices
feature three enable inputs: two active low (E
1
, E
2
) and one active high (E
3
).
All outputs are high unless E
1
and E
2
are low and E
3
is high. This multiple-enable function allows easy parallel
expansion of the device to a 1-of-32 (five lines to 32 lines) decoder with just four ’FCT138T devices and one
inverter.
These devices are fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the
outputs, preventing damaging current backflow through the device when it is powered down.
