General Description
IDT74FCT138 General 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.
