IDT IDT54AHCT138
The IDT54174AHCT138 are 1-of-8 decoders built using advanced CEMOS", a dual metal CMOS technology. The IDT54/74AHCT138 accepts three binary weighed inputs (Ao, A" AiJ and, when enabled, provides eight mutually exclusive aciive lOW outputs (00-07), The IDT54/74AHCT138 features three enable inputs, two active lOW (f" E 2) and one active HIGH (E3)' All outpus will be HIGH unless E, andE2 are lOW and E3 is HIGH. This multiple enable function allows easy parallel expansion of the device to aFEATURES
:● Equivalent to AlS speeds and output drive over full temperature and voltage supply extremes
● 11 ns typical address to output delay
● IOl = 14mA over full military temperature range
● CMOS power levels (5/lW typo static)
● Both CMOS and TTL output compatible
● Substantially lower input current levels than AlS (5/lA max.)
● 1-of-8 decoder with enables
● 100% product assurance screening to Mll-STD-883, Class B is available
● JEDEC standard pinout for DIP and lCC
