This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits. • • • • • • • • • Inputs Accept Voltages to 5.5 V Max tpd of 7.9 ns at 3.3 V Low Power Consumption, 10 µA Max ICC ±24 mA Output Drive at 3.3 V Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C Ioff Supports Partial Power Down Mode Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) DCU PACKAGE (TOP VIEW) CLK D Q GND 1 8 VCC 2 7 3 6 4 5 PRE CLR Q DESCRIPTION/ORDERING INFORMATION This single positive edge triggered D-type flip-flop is designed for 1.65-V to 5.5-V VCC operation. A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs. This device is fully specified for partial power down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
