Описание SN74HC74DR
The SN74HC74DR is a dual D-type Positive-Edge-Triggered Flip-flop with clear and preset. The SNx4HC74 device contains two independent D-type positive-edge-triggered flip-flops. A low level at the preset (PRE) or clear (CLR) inputs 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 are transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of CLK. Following the hold-time interval, data at the D input can be changed without affecting the levels at the outputs. It is suitable for ultrasound system, lab instrumentation and vacuum cleaners.
• Outputs can drive up to 10 LSTTL loads
• 40µA Maximum low power consumption
• 15ns Typical tpd
• ±4mA Output drive at 5V
• 1µA Very low input current
• ±25mA Continuous output current
• ±50mA Continuous current through VCC or GND
