SEMICONDUCTOR TECHNICAL DATA
Dual 1-of-4 Decoder/
Demultiplexer
High–Performance Silicon–Gate CMOS
The MC54/74HC139A is identical in pinout to the LS139. The device
inputs are compatible with standard CMOS outputs; with pullup 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.
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 µA
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

* Maximum Ratings are those values beyond which damage to the device may occur.
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance cir-
cuit. For proper operation, Vin and
v vVout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
Functional operation should be restricted to the Recommended Operating Conditions.

PIN DESCRIPTIONS
ADDRESS INPUTS
A0a, A1a, A0b, A1b (Pins 2, 3, 14, 13)
Address inputs. These inputs, when the respective 1–of–4
decoder is enabled, determine which of its four active–low
outputs is selected.
CONTROL INPUTS
Selecta, Selectb (Pins 1, 15)
Active–low select inputs. For a low level on this input, the
outputs for that particular decoder follow the Address inputs.
A high level on this input forces all outputs to a high level.
OUTPUTS
Y0a – Y3a, Y0b – Y3b (Pins 4 – 7, 12, 11, 10, 9)
Active–low outputs. These outputs assume a low level
when addressed and the appropriate Select input is active.
These outputs remain high when not addressed or the ap-
propriate Select input is inactive.
