Additional Details
The TC74LCX373FT features octal D-type latches with three-state outputs. Each latch independently stores one bit of data. When the Latch Enable (LE) input is high, the Q outputs follow the data at the D inputs. When LE transitions low, the data present at the D inputs is latched and retained. The Output Enable (OE) input controls the three-state outputs. When OE is low, the outputs are enabled, and the latched data is available. When OE is high, the outputs are in a high-impedance state.
The device is available in a TSSOP20 (Thin Shrink Small Outline Package) which helps in miniaturization of electronic circuits.
