MICROCIRCUIT DATA SHEET Original Creation Date: 07/01/96 Last Update Date: 03/09/99 Last Major Revision Date: 12/16/98 MN54ACQ373-X REV 2A0 Octal Transparent Latch with TRI-STATE Outputs General Description The ACQ373 consists of eight latches with TRI-STATE outputs for bus organized system applications. The latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is low, the data satisfying the input timing requirements 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. The ACQ utilizes NSC Quiet Series technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series TM features GTO TM output control and undershoot corrector in addition to a split ground bus for superior performance.
