SEMICONDUCTOR TECHNICAL DATA
1-of-8 Decoder/Demultiplexer
High–Performance Silicon–Gate CMOS
The MC54/74HC138A is identical in pinout to the LS138. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
The HC138A decodes a three–bit Address to one–of–eight active–low
outputs. This device features three Chip Select inputs, two active–low and
one active–high to facilitate the demultiplexing, cascading, and chip–select-
ing functions. The demultiplexing function is accomplished by using the
Address inputs to select the desired device output; one of the Chip Selects is
used as a data input while the other Chip Selects are held in their active

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.
