Product Summary

The IDT54FCT138ADB is a 1-of-8 decoder built using an advanced dual metal CMOS technology. The IDT54FCT138ADB accepts three binary weighted inputs (A0, A1, A2) and, when enabled, provide eight mutually exclusive active LOW outputs (O0 - O7). The IDT54FCT138ADB features 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 IDT54FCT138ADB devices and one inverter.
