The ’HC533, ’HCT533, ’HC563, and CD74HCT563 are
high-speed Octal Transparent Latches manufactured with
silicon gate CMOS technology. They possess the low power
consumption of standard CMOS integrated circuits, as well as
the ability to drive 15 LSTTL devices.
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
is independent of the state of the output enable.
The ’HC533 and ’HCT533 are identical in function to the
’HC563 and CD74HCT563 but have different pinouts. The
’HC533 and ’HCT533 are similar to the ’HC373 and ’HCT373;
the latter are non-inverting types.
