  • Description

    The IDT74FCT138ATQ is a 1-of-8 decoder built using an advanced dual metal CMOS technology. It accepts three binary weighted inputs (A0, A1, A2) and provides eight mutually exclusive active low outputs (O0- O7) when enabled. The decoder features three enable inputs, two active low (E1, E2) and one active high (E3). Outputs will be high unless E1 and E2 are low and E3 is high. This device allows for easy parallel expansion to a 1-of-32 decoder with the use of four IDT74FCT138ATQ devices and one inverter.
