Features  
Description  
• CD74AC138, CD74ACT138 . . . . . . . . . . . . . . . Inverting The CD74AC138, CD74ACT138, CD74AC238, and  
CD74ACT238 are 3-to-8-line decoders/demultiplexers that  
utilize the Harris Advanced CMOS Logic technology. Both  
• CD74AC238, CD74ACT238 . . . . . . . . . . . Non-Inverting  
circuits have three binary select inputs (A0, A1, and A2). If  
the device is enabled, these inputs determine which one of  
the eight normally HIGH outputs of the AC/ACT138 will go  
LOW or which on of the normally LOW outputs of the  
AC/ACT238 will go HIGH. Two active LOW and one active  
HIGH enables (E1, E2 and E3) are provided to simplify the  
cascading of these devices.
