QS S74FCT139A FAST CMOS DUAL 1-OF-4 DECODER WITH ENABLE - SO16 SMD

Manufactured by Quality Semiconductor Inc. (now IDT) - SO16 SMD package - supplied on cut tape

DESCRIPTION

The S74FCT139A is a dual 1-of-4 decoder built using an advanced dual metal CMOS technology. These devices have two independent decoders, each of which accept two binary weighted inputs (A0-A1) and provide four mutually exclusive active LOW outputs (O0-O3). Each decoder has an active LOW enable (E). When E is HIGH, all outputs are forced HIGH.

FEATURES

• 74FCT139A 35% faster than FAST
• Equivalent to FAST output drive over full temperature and voltage supply extremes
• IOL = 48mA (commercial)
• CMOS power levels (1mW typ. static)
• TTL input and output level compatible
• CMOS output level compatible
• Substantially lower input current levels than FAST (5µA max.)
