DESCRIPTION:
The IDT54/74FCT138/A/C are 1-of-8 decoders built using
an advanced dual metal CMOS technology. The IDT54/
74FCT138/A/C accept three binary weighted inputs (A0, A1,
A2) and, when enabled, provide eight mutually exclusive
active LOW outputs (O0 - O7). The IDT54/74FCT138/A/C
feature three enable inputs, two active LOW (E1, E2) and one
active HIGH (E3). All outputs will be HIGH unless E1 and E2
are LOW and E3 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 IDT54/74FCT138/A/C devices
and one inverter.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. This parameter is guaranteed but not tested.
