SN54AC563 OCTAL D-TYPE TRANSPARENT LATCHES

ordering information The ’AC563 devices are octal D-type transparent 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

etained or new data can be entered while the outputs are in the high-impedance state. 8D GND CLK 8Q SN54AC563, SN74AC563 OCTAL DĆTYPE TRANSPARENT LATCHES WITH 3ĆSTATE OUTPUTS SCAS552C − NOVEMBER 1995 − REVISED OCTOBER 2003 SN54AC563 . . .
