MM74HC139
Dual 2-To-4 Line Decoder
General Description
The MM74HC139 decoder utilizes advanced silicon-gate
CMOS technology, and is well suited to memory address
decoding or data routing applications. It possesses the
high noise immunity and low power consumption usually
associated with CMOS circuitry, yet has speeds compara-
ble to low power Schottky TTL logic.
The MM74HC139 contain two independent one-of-four
decoders each with a single active low enable input (G1, or
G2). Data on the select inputs (A1, and B1 or A2, and B2)
cause one of the four normally high outputs to go LOW.
The decoder’s outputs can drive 10 low power Schottky
TTL equivalent loads, and are functionally as well as pin
equivalent to the 74LS139. All inputs are protected from
damage due to static discharge by diodes to VCC and
ground.
