SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX138 is a high performance, 1–of–8 decoder/  
demultiplexer operating from a 2.7 to 3.6V supply. High impedance TTL  
compatible inputs significantly reduce current loading to input drivers  
while TTL compatible outputs offer improved switching noise  
LOW–VOLTAGE CMOS  
DECODER/DEMULTIPLEXER  
performance. A V specification of 5.5V allows MC74LCX138 inputs to be  
I
safely driven from 5V devices. The MC74LCX138 is suitable for memory  
address decoding and other TTL level bus oriented applications.  
The MC74LCX138 high–speed 1–of–8 decoder/demultiplexer accepts  
three binary weighted inputs (A0, A1, A2) and, when enabled, provides  
eight mutually exclusive active–LOW outputs (O0–O7). The LCX138  
features three Enable inputs, two active–LOW (E1, E2) and one  
active–HIGH (E3). All outputs will be HIGH unless E1 and E2 are LOW,  
and E3 is HIGH. This multiple enabled function allows easy parallel  
expansion of the device to a 1–of–32 (5 lines to 32 lines) decoder with just  
four LCX138 devices and one inverter (See Figure 1). The LCX138 can  
be used as an 8–output demultiplexer by using one of the active–LOW  
Enable inputs as the data input and the other Enable inputs as strobes.  
The Enable inputs which are not used must be permanently tied to their  
appropriate active–HIGH or active–LOW state.
