• Manufacturer Part Number: MC74F139
• Description: DUAL 1-OF-4 DECODER FAST SHOTTKY TTL
• Manufacturer: Motorola

GUARANTEED OPERATING RANGES
DC CHARACTERISTICS OVER OPERATING TEMPERATURE RANGE (unless otherwise specified)
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable device type.
2. Not more than one output should be shorted at a time, nor for more than 1 second.
AC CHARACTERISTICS
fabricated with the Schottky barrier diode process. The device
has two independent decoders, each of which accepts two
binary weighted inputs (A O , A 1 ) and provide four mutually ex-
clusive active LOW outputs (O 0 -O 3 ). Each decoder has an ac-
tive LOW Enable (E). When E is HIGH all outputs are forced
HIGH. The enable can be used as the data input for a 4-output
demultiplexer application.

and thereby reducing the number of packages required in a
logic network.
