FAST CMOS
1-OF-8 DECODER
WITH ENABLE
Integrated Device Technology, Inc.
DESCRIPTION:
The IDT54/74FCT138T/AT/CT are 1-of-8 decoders built
using an advanced dual metal CMOS technology. The IDT54/
74FCT138T/AT/CT accepts three binary weighted inputs (A
0
,
A
1
, A
2
) and, when enabled, provides eight mutually exclusive
active LOW outputs (
O
0
-
O
7
). The IDT54/74FCT138T/AT/CT
features three enable inputs, two active LOW (
E
1
,
E
2
) and one
active HIGH (E
3
). All outputs will be 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 (5 lines to
32 lines) decoder with just four IDT54/74FCT138T/AT/CT
devices and one inverter.
