74LVC138A
3-to-8 line decoder/demultiplexer; inverting
Rev. 6 — 23 January 2019
Product data sheet
1. General description
The 74LVC138A is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted address
inputs (A0, A1 and A2) and, when enabled, provides eight mutually exclusive outputs (Y0 to Y7)
that are LOW when selected.
There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3).
Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.
This multiple enable function allows easy parallel expansion of the device to a 1-of-32
(5 lines to 32 lines) decoder with just four 74LVC138A devices and one inverter.
The 74LVC138A can be used as an eight output demultiplexer by using one of the active LOW
enable inputs as the data input and the remaining enable inputs as strobes. Unused enable inputs
must be permanently tied to their appropriate active HIGH or LOW state.

Typical values are measured at Tamb = 25 °C and VCC = 1.2 V, 1.8 V, 2.5 V, 2.7 V, and 3.3 V respectively.
tpd is the same as tPLH and tPHL.
Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.
CPD is used to determine the dynamic power dissipation (PD in μW).

PD = CPD × VCC × fi × N + ∑(CL × VCC × fo) where:
fi = input frequency in MHz; fo = output frequency in MHz
CL = output load capacitance in pF
VCC = supply voltage in V
N = number of inputs switching

∑(CL × VCC × fo) = sum of outputs
