U74LVC563 - OCTAL TRANSPARENT D-TYPE LATCHES

General Description

The U74LVC563 is a octal transparent D-TYPE latches with 3-state outputs.

When the latch-enable (LE) is high, the Q outputs follow the complements of the D inputs.

When LE is low, the Q outputs are latched at the inverses of the levels set up at the D inputs.

Key Features

  • ES.
  • Wide supply voltage range from 1.65V to 3.6V.
  • Max tPD of 6.8 ns from D to Q at 3.3V.
  • Max tPD of 7.6 ns from LE to Q at 3.3V.
  • Up to 5.5V inputs accept voltages.
  • Low power consumption, ICC = 10μA (Max. ) at 3.6V.
  • ±24mA output driver at 3V.
  • IOFF supports partial-power-down mode operation.

UNISONIC TECHNOLOGIES CO., LTD U74LVC563 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS „ DESCRIPTION CMOS IC The U74LVC563 is a octal transparent D-TYPE latches with 3-state outputs. When the latch-enable (LE) is high, the Q outputs follow the complements of the D inputs. When LE is low, the Q outputs are latched at the inverses of the levels set up at the D inputs. When the output-enable ( OE ) input is high, the Q outputs are in a high-impedance state, and the outputs neither load nor drive the bus lines. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pull-up components. While the outputs are in the high-impedance state, old data can be retained or new data can be entered, i.e.
