The outputs are transparent to the inputs when the latch enable (LE) is high. When the LE goes low, the data is latched. 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 ACS373MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of the radiation hardened, high-speed, CMOS/SOS Logic Family.

Index area: A notch or a pin one identification mark shall be located adjacent to pin one and shall be located within the shaded area shown. The manufacturer’s identification shall not be used as a pin one identification mark. Alternately, a tab (dimension k) may be used to identify pin one. 5. N is the maximum number of terminal positions. 6. Measure dimension S1 at all four corners. 7. For bottom-brazed lead packages, no organic or polymeric materials shall be molded to the bottom of the package to cover the leads. 2. If a pin one identification mark is used in addition to a tab, the limits of dimension k do not apply. 8. Dimension Q shall be measured at the point of exit (beyond the meniscus) of the lead from the body. Dimension Q minimum shall be reduced by 0.0015 inch (0.038mm) maximum when solder dip lead finish is applied. 3. This dimension allows for off-center lid, meniscus, and glass overrun. 4. Dimensions b1 and c1 apply to lead base metal only. Dimension M applies to lead plating and finish thickness. The maximum limits of lead dimensions b and c or M shall be measured at the centroid of the finished lead surfaces, when solder dip or tin plate lead finish is applied. 9. Dimensioning and tolerancing per ANSI Y14.5M - 1982. 10. Controlling dimension: INCH.
