SN74HC74DBR Part Information

Details for SN74HC74DBR by Texas Instruments

Semiconductors - ICs>Logic>Flip Flops

Part Description

The SNx4HC74 devices contain two independent Dtype 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 holdtime interval, data at the D input can be changed without affecting the levels at the outputs.
