TRI-STATE OCTAL BUFFERS
The SN54 / 74LS795 thru SN54 / 74LS798 device types provide a second source for the 71 / 81LS95 thru 71 / 81LS98 series. These devices are octal low power Schottky versions of the 70/8095 thru 70/8098 3-STATE Hex Buffers. The LS795 and LS797 are noninverting and the LS796 and LS798 are inverting functions. On each buffer, one of the two inputs is used as a control line to gate the output into the high impedance state, while the other input passes the data through the buffer. On the LS795 and LS796 access is through a 2-input NOR gate, with all eight 3-STATE enable lines common. On the LS797 and LS798, four buffers are enabled from one common line and the other four buffers from another common line. On all device types the 3-STATE condition is achieved by applying a high logic level to the enable pins. TRUTH TABLES LS795
