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 that meets the setup-time requirements are transferred to the outputs on the low-to-high transition of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the D input may be changed without affecting the levels at the outputs. The 74AC11074 is characterized for operation from –40°C to 85°C.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils, except for the N package, which has a trace length of zero. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 74AC11074 DUAL POSITIVE-EDGE-TRIGGERED D-TYPE FLIP-FLOP WITH CLEAR AND PRESET SCAS499A – DECEMBER 1986 – REVISED APRIL 1996 recommended operating conditions VCC Supply voltage VIH High-level input voltage VCC = 3 V VCC = 4.5 V MIN NOM MAX 3 5 5.5 0.9 Low-level input voltage VI VO Input voltage 0 Output voltage 0 IOH High-level output current ∆t/∆v Input transition rise or fall rate TA Operating free-air temperature V 3.85 VIL Low-level output current V 2.1 3.15 VCC = 5.5 V VCC = 3 V IOL UNIT VCC = 4.5 V VCC = 5.5 V 1.35 V 1.65 VCC VCC VCC = 3 V VCC = 4.5 V –24 VCC = 5.5 V –24 VCC = 3 V VCC = 4.5 V 12 V V –4 24 VCC = 5.5 V mA mA 24 0 10 ns/V –40 85 °C electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS IOH = –50 µA VOH VOL IOH = –4 mA Ci TA = 25°C MIN TYP MAX MIN 3V 2.9 2.9 4.5 V 4.4 4.4 5.5 V 5.4 5.4 3V 2.58 2.48 3.8 MAX 4.5 V 3.94 5.5 V 4.94 IOH = –75 mA† 5.5 V 3V 0.1 0.1 IOL = 50 µA 4.5 V 0.1 0.1 5.5 V 0.1 0.1 IOL = 12 mA IOL = 75 mA† VI = VCC or GND 4.8 3.85 3V 0.36 0.44 4.5 V 0.36 0.44 5.5 V 0.36 0.44 5.5 V IO = 0 5.5 V 5V V 1.65 5.5 V VI = VCC or GND, VI = VCC or GND UNIT V IOH = –24 24 mA A IOL = 24 mA II ICC VCC 3.5 ±0.1 ±1 µA 4 40 µA pF † Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms.
