DESCRIPTION:

The IDT54/74FCT138T is a 1-of-8 decoder built using an advanced dual metal CMOS technology. The IDT54/74FCT138T accepts three binary weighted inputs (A0, A1, A2) and, when enabled, provides eight

mutually exclusive active low outputs (O0- O7). The IDT54/74FCT138T features three enable inputs, two active low (E1, E2) and one active high (E3). All outputs will be high unless E1and E2are low and E3is 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 devices and one inverter.
