74VHC138  
3-to-8 Decoder/Demultiplexer  
0V to 7V can be applied to the input pins without regard to  
the supply voltage. This device can be used to interface 5V  
to 3V systems and two supply systems such as battery  
back up. This circuit prevents device destruction due to  
mismatched supply and input voltages.  
General Description  
The VHC138 is an advanced high speed CMOS 3-to-8  
decoder/demultiplexer fabricated with silicon gate CMOS  
technology. It achieves the high speed operation similar to  
equivalent Bipolar Schottky TTL while maintaining the  
CMOS low power dissipation.  
Features  
When the device is enabled, 3 binary select inputs (A0, A1  
and A2) determine which one of the outputs (O0–O7) will go  
LOW. When enable input E3 is held LOW or either E1 or E2  
High Speed: tPD = 5.7ns (typ) at TA = 25°C  
Low power dissipation: ICC = 4 µA (max.) at TA = 25°C  
High noise immunity: VNIH = VNIL = 28% VCC (min.)  
is held HIGH, decoding function is inhibited and all outputs  
go HIGH. E3, E1 and E2 inputs are provided to ease cas-  
Power down protection provided on all inputs  
Pin and function compatible with 74HC138  
cade connection and for use as an address decoder for  
memory systems. An input protection circuit ensures that
