HD74LV138A
a
3-to-8 line Decoder / Demultiplexers
ADE-205-261 (Z)
1st Edition
March 1999
Description
The HD74LV138A is designed to be used in high-performance memory-decoding or data-routing applica-
tions requiring very short propagation delay times. The conditions at the binary-select inputs and the three
enable inputs select one of eight input lines.
Two active-low and one active-high enable inputs reduce the need for external gates or inverters when ex-
panding. A 24-line decoder can be implemented without external inverters and a 32-line decoder requires
only one inverter.
An enable input can be used as a data input for demultiplexing applications.
Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook comput-
ers), and the low-power consumption extends the battery life.

Notes:The absolute maximum ratings are values which must not individually be exceeded, and furthermore,
no two of which may be realized at the same time.
1.The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.
2.This value is limited to 5.5 V maximum.
3.The maximum package power dissipation was calculated using a junction temperature of 150°C.
