74HC138 (3 to 8 Line Decoder- Demultiplexer) Infrared Object Detection Sharp IR Proximity (GP2Y0A02YK0F) isIntroduction : The 74HC138 decodes three binary weighted address inputs (A0, A1 and A2) toeight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1, E2 andE3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enablefunction allows easy parallel expansion to a 1 of 32 (5 to 32 lines) decoder with just four '138 ICsand one inverter. 74HC138 can be used as an eight output demultiplexer by
