Technical specifications
| Specification | Value | Notes |
|---|---|---|
| Logic function | Dual D flip-flops with clear and preset | |
| Recommended supply voltage | 4.5 to 5.5 V | Recommended operating conditions; use the exact ACS or ACTS electrical table for input thresholds. |
| Operating case temperature | -55°C to +125°C | Recommended operating conditions; prototype screening may be room-temperature only. |
| Package options | 14-pin DIP; 14-lead flatpack | Package availability depends on orderable variant. |
| Screening process options | QML Q or QML V | Select the applicable ordering option; prototype flow does not imply QML screening. |
| Total-dose capability | Up to 1 Mrad(Si) | Radiation-assured ordering option only; specify applicable SMD RHA level. Prototype/commercial flows do not imply radiation assurance. |
Values are subject to the conditions and ordering options in the referenced product documentation.
Product overview
UT54ACS74 contains two independent D-type flip-flops that capture data on the positive-going clock edge. Active-low preset and clear inputs set or reset the outputs independently of the data and clock inputs. Data meeting the setup and hold requirements transfers to the outputs when preset and clear are inactive. Its recommended supply range is 4.5 to 5.5 V. The device is characterized over a case-temperature range of -55°C to +125°C. QML Q and QML V process options are documented; select the orderable device and screening level for the required application.
