1-of-8 Decoder

The FCT138T devices are 1-of-8 decoders. These devices accept three binary weighted inputs (A0, A1, A2) and, when enabled, provide eight mutually exclusive active-low outputs (O0O7). The FCT138T devices feature three enable inputs: two active low (E1, E2) and one active high (E3). All outputs are 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 (five lines to 32 lines) decoder with just four FCT138T devices and one inverter. These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. By Texas Instruments
