SN74AC533 OCTAL TRANSPARENT D-TYPE LATCHES

ordering information The ’AC533 devices are octal transparent D-type latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs follow the complements of the data (D) inputs. When LE is taken low, the Q outputs are latched at the inverse logic levels set up at the D inputs. A buffered output-enable (OE) input can be used to place t.

Features

ts. OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. 4Q GND LE SN54AC533 . . .
