MC74HC139A
Dual 1−of−4 Decoder/
Demultiplexer
High−Performance Silicon−Gate CMOS
The MC74HC139A is identical in pinout to the LS139. The device
inputs are compatible with standard CMOS outputs; with pull−up
resistors, they are compatible with LSTTL outputs.
This device consists of two independent 1−of−4 decoders, each of
which decodes a two−bit Address to one−of−four active−low outputs.
Active−low Selects are provided to facilitate the demultiplexing and
cascading functions. The demultiplexing function is accomplished by
using the Address inputs to select the desired device output, and
utilizing the Select as a data input.
Features
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
• Chip Complexity: 100 FETs or 25 Equivalent Gates
• Pb−Free Packages are Available*

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. IO absolute maximum rating must be observed.
2. Tested to EIA/JESD22−A114−A.
3. Tested to EIA/JESD22−A115−A.
4. Tested to JESD22−C101−A.
5. Tested to EIA/JESD78.
6. For high frequency or heavy load considerations, see Chapter 2the ON Semiconductor High−Speed CMOS Data Book (DL129/D).
