Description
• Common Latch-Enable Control
• Common Three-State Output Enable Control
• Buffered Inputs
The Harris CD74HC533, CD74HCT533, CD74HC563, and
CD74HCT563 are high speed Octal Transparent Latches
manufactured with silicon gate CMOS technology. They pos-
sess the low power consumption of standard CMOS inte-
grated circuits, as well as the ability to drive 15 LSTTL
devices.

• Three-State Outputs
• Bus Line Driving Capacity
The outputs are transparent to the inputs when the latch
enable (LE) is high. When the latch enable (LE) goes low the
data is latched. The output enable (OE) controls the three-
state outputs. When the output enable (OE) is high the
outputs are in the high impedance state. The latch operation

The CD74HC533 and CD74HCT533 are identical in function
to the CD74HC563 and CD74HCT563 but have different
pinouts. The CD74HC533 and CD74HCT533 are similar to
the CD74HC373 and CD74HCT373; the latter are non-
inverting types.
