The
KK
74LV138 is a low-voltage Si-gate CMOS device and is pin
and function compatible 74HCT138.
The74LV138 accepts three binary weighted address inputs -
(A
0
,A
1
,A
2
) and when enabled, provide 8 - mutually exclusive active
LOW outputs (Y
0
to Y
7
).
The “138” features three enable inputs: two active LOW (CS
2
,CS
3
and one active HIGH (CS
1
).Every output will be HIGH unless CS
2
, and
CS
3
are LOW and CS
1
is HIGH.
Optimized for Low Voltage applications:1.2 to 3.6 V
Demultiplexing capability
Multiple input enable for easy expansion
Ideal for memory chip select decoding
Active LOW mutually exclusive outputs
Output capability: standard
