FEATURES:
• Equivalent to ALS speeds and output drive over full
temperature and voltage supply extremes
• 9ns typical address to output delay
• IOL = 14mA over full military temperature range
• CMOS power levels (5p.W typo static)
• Both CMOS and TTL output compatible
• Substantially lower input current levels than ALS (Sp.A max.)
• DuaI1-of-4 decoder with enable
• 100% product assurance screening to MIL-STD-883, Class B
is available
• JEDEC standard pinout for DIP and LCC
DESCRIPTION:
The IDTS4174AHCT139 are dual 1-of-4 decoders built using
advanced CEMOS'·, a dual metal CMOS technology. The device
has two independent decoders, each of which accept two binary
weighed inputs (Ao-A 1) and provides four mutually exclusive
active LOW outputs (0 0-0 3), Each decoder has an active LOW
enable (E). When E is HIGH, all outputs are forced HIGH.
