They pos- sess the low power consumption of standard CMOS inte- grated 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 to the state of the output enable. 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. Ordering Information PART NUMBER TEMP. RANGE (oC) PACKAGE PKG. NO.
