They possess the low power consumption of standard CMS integrated circuits, as well as the ability to drive 15 LSTTL devices. The C74HCT373 and C74HCT573 are functionally as well as pin compatible with the standard 74LS373 and 74LS573. 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 (E) controls the threestate outputs. When the output enable (E) is high the outputs are in the high impedance state. The latch operation is independent to the state of the output enable. The 373 and 573 are identical in function and differ only in their pinout arrangements. rdering Information PART NUMBER TEMP.
