FEATURES
1.2μ CMOS - Latchup immune High speed Low power consumption Single 5 volt supply Available QML Q or V processes Flexible package - 14-pin DIP - 14-lead flatpack UT54ACS74 - SMD 5962-96534 UT54ACTS74 - SMD 5962-96535 DESCRIPTION
A low level at the Preset or Clear inputs sets or resets the outputs regardless of the levels of the other inputs. Following the hold time interval, data at the D input may be changed without affecting the levels at the outputs.

The output levels in this configuration are not guaranteed to meet the minimum levels for VOH if the lows at preset and clear are near VIL maximum. In addition, this configuration is nonstable; that is, it will not persist when either preset or clear returns to its inactive (high) level.
