IDT54FCT139CTDB

FAST CMOS双1 - OF- 4解码器启用 FAST CMOS DUAL 1-OF-4 DECODER WITH ENABLE

DESCRIPTION:

The IDT54/74FCT139T/AT/CT are dual 1-of-4 decoders 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:

• Std., A and C speed grades

• Low input and output leakage ≤1µA max.

• CMOS power levels

• True TTL input and output compatibility

   – VOH = 3.3V typ.
