74HC138; 74HCT138
3-to-8 line decoder/demultiplexer; inverting
Rev. 03 — 23 December 2005
Product data sheet
1. General description
The 74HC138; 74HCT138 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL).
The 74HC138; 74HCT138 decoder accepts three binary weighted address inputs (A0, A1
and A3) and when enabled, provides 8 mutually exclusive active LOW outputs (Y0 to Y7).
The 74HC138; 74HCT138 features 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 74HC138; 74HCT138
to a 1-of-32 (5 lines to 32 lines) decoder with just four 74HC138; 74HCT138 ICs and one
inverter.
The 74HC138; 74HCT138 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. Not used enable inputs must be permanently tied to their appropriate active
HIGH- or LOW-state.
The 74HC138; 74HCT138 is identical to the 74HC238; 74HCT238 but has inverting
outputs.
2. Features
■ Demultiplexing capability
■ Multiple input enable for easy expansion
■ Complies with JEDEC standard no. 7A
■ Ideal for memory chip select decoding
■ Active LOW mutually exclusive outputs
■ ESD protection:
◆ HBM EIA/JESD22-A114-C exceeds 2000 V
◆ MM EIA/JESD22-A115-A exceeds 200 V
■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C

[1] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × 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;
Σ(CL × VCC2 × fo) = sum of the outputs.

PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × 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;
Σ(CL × VCC2 × fo) = sum of the outputs.
