74HC238-Q100; 74HCT238-Q100
3-to-8 line decoder/demultiplexer
Rev. 2 — 13 June 2018
Product data sheet
1 General description
The 74HC238-Q100; 74HCT238-Q100 decodes three binary weighted address inputs
(A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three
enable inputs (E1 and E2 and E3). Every output will be LOW unless E1 and E2 are LOW
and E3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32
(5 to 32 lines) decoder with just four '238 ICs and one inverter. The '238 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. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
VCC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.

[3] CPD is used to determine the dynamic power dissipation (PD in μW):
PD = CPD x VCC2 x fi x N + ∑ (CL x VCC2 x 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 x VCC2 x fo) = sum of outputs.
