MICROCIRCUIT DATA SHEET Original Creation Date: 07/01/96 Last Update Date: 03/31/97 Last Major Revision Date: 07/01/96 MN54AC373-X REV 1B0 Octal Transparent Latch with TRI-STATE Outputs General Description The AC373 consists of eight latches with 3-state outputs for bus organized system applications. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When (OE) is HIGH the bus output is in the high impedance state.
