74373 IC eight latches with 3-state outputs

74HC series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS technology and 74HC373 is one of them. 74HC373 ICs contain eight D-type latches with 3-Output states i.e. High, Low, and High Impedance. 74HC373 provides Latch-Enable (LE) input pin and when it’s high, the Q outputs follow the data (D) inputs. When LE is low, the device does not change the previous logic. ts. A buffered output-enable (OE)’ input can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. OE’ does not affect the internal stored logic.
