ON NLV74HC138ADR2G 1-of-8 decoder/ demultiplexer Datasheet

MC74HC138A
1-of-8 Decoder/
Demultiplexer
High−Performance Silicon−Gate CMOS
The MC74HC138A 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−selecting 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 states.

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 circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v 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.
