The 74HC373RPEL is an octal transparent latch with 3-state outputs manufactured by Renesas Electronics America. This device is part of the 74HC series of high-speed CMOS logic devices, offering improved performance compared to standard CMOS logic. The 74HC373RPEL features eight D-type latches with individual inputs and a common enable (LE) and output enable (OE) control. When the latch enable (LE) is high, the Q outputs follow the data (D) inputs. When LE transitions low, the data present at the D inputs at that moment is latched. The 3-state outputs are controlled by the output enable (OE) input. When OE is low, the outputs are enabled; when OE is high, the outputs are in a high-impedance state.
