MC74AC373, MC74ACT373 Octal Transparent Latch with 3State Outputs The MC74AC373/74ACT373 consists of eight latches with 3state outputs for bus organized system applications. The flipflops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time 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.
