SN54/74LS795
SN54/74LS796
TRI-STATE OCTAL BUFFERS SN54/74LS797
SN54/74LS798
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 TRI-STATE OCTAL BUFFERS
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 LOW POWER SCHOTTKY
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.
