description  
The ’FCT138T devices are 1-of-8 decoders. These devices accept three binary weighted inputs (A , A , A )  
0

2
and, when enabled, provide eight mutually exclusive active-low outputs (O –O ). The ’FCT138T devices  
0

feature three enable inputs: two active low (E , E ) and one active high (E ).

All outputs are high unless E and E are low and E 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 I . The I circuitry disables the  
off  
off  
outputs, preventing damaging current backflow through the device when it is powered down.
