There are three binary select inputs (A, B, and C) which determine which one of the eight outputs (Y0-Y7) will go high. This chip has three enable inputs (G1, ~G2A, and ~G2B); when any enable pins are brought low (or high in G1's case), all output pins are pulled low.\n\n This is a great tool if you need to increase the number of outputs on your micrcontroller. For example, it's used in the [3x3x3 LED Cube](http:\/\/www.sparkfun.com\/commerce\/product_info.php?products_id=9391) to help an ATmega168 control the 27 LEDs.\n\n This device comes in a 16-pin DIP package.\n\n**Features:**\n\n* High speed\n* Wide operating voltage range (2 to 6VDC)\n* Low power dissipation (~4\u00b5A)\n* High noise immunity\n* Symmetrical output impedance\n* Balanced propagation delays\n* Inputs equipped with protection circuits against static discharge and transient excess voltage\n\n**Documents:**\n\n* [Datasheet](http:\/\/www.sparkfun.com\/datasheets\/Components\/General\/COM-09577-m74hc238.pdf)\n\n","date_published":"2009-12-15 15:19:23-07","price":0.95,"qty_price":{"1":0.95,"25":0.9,"100":0.86},"in_stock":false,"backorder_allowed":false,"is_rohs_compliant":true,"is_export_controlled":false,"is_oshw":false,"in_eagle_library":true,"in_fritzing_library":false,"sparkfun_original":false,"hstariff":"8542.39.0000","pack_length":"50mm","pack_width":"9mm","pack_height":"8mm","packed_weight":"0.0022lbs","ascii_art":"\n\n\n\n\n\n\n\n\n ;d00xc'\n ,d0KKKKKKKO;\n .l0KK0O0KKKKKKOc'...\n .ckKK0KOOkkOKKKKKKKKKK00d:.\n .:xKK0kOOkkOOOk0KKKKKKKKKKKK00x.\n .:kK0000K0xO0OO0KKKKKKKKKKKKKK00K0c\n ,dKKK000O000K0OKKKKKKKKKKKKKKKKKKKKOx\n 'o0KK00KKK0KKKKKKKKKKKKKKKKKKKKKKKKXKO;...\n .cOKK0O0K0KKKKKKKKKKXKKKKKKKKKKKKKK0kxdOOx;,.\n .:xKK00KKKKKXXXXXXXXKKKXKKKKKKKKKXXXXO;..';..;,.\n ;xKKKK0OKK000KKXXXXKKKK0O0KKKKKKKKK0O0KKd:;,.
