description
These 3-line to 8-line decoders/demultiplexers
are designed for 2.7-V to 5.5-V VCC operation.
The ’LV138 are designed for high-performance
memory-decoding or data-routing applications
requiring very short propagation delay times. In
high-performance memory systems, this decoder
can be used to minimize the effects of system
decoding. When employed with high-speed
utilizing a fast enable circuit, the delay times of this
decoder and the enable time of the memory are
usually less than the typical access time of the
memory. This means that the effective system
delay introduced by the decoder is negligible.
The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. Two
active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding.
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.
The SN74LV138 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LV138 is characterized for operation over the full military temperature range of –55
°C to 125°C. The
SN74LV138 is characterized for operation from –40
°C to 85°C.
