MC74AC373

MC74AC373, MC74ACT373 Octal Transparent Latch with 3-State Outputs The MC74AC373/74ACT373 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 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.
