The 74LVC139A is a dual 2-line to 4-line decoder/ demultiplexer, which can decode two binary weighted address inputs to four mutually exclusive outputs.
The nA0 and nA1 are two binary address inputs that determine which of the four normally high outputs (nY0 to nY3) of the device will in low-state. Each decoder has an enable input of 1E and 2E respectively. All of the outputs are in a high-state except the case that 1E and 2E are low. The outputs are enabled only when all 1E and 2E are active. When the device operates as a 1-line to 4-line demultiplexer, one of the active-low enable inputs is used as data input. Both 3.3V and 5V devices can drive inputs, enabling this device to operate as translator in a mixed 3.3V and 5V system environment.
All inputs support Schmitt-Trigger action, which allows the circuit to tolerate slower input rise and fall times.
The 74LVC139A is available in Green SOIC-16 and TSSOP-16 packages. It operates over a temperature range of -40℃ to +125℃.
