The input disable allows the flip-flops to remain in their present states without having to disrupt the clock.

Data on these pins, when enabled by the. A high level on this pin resets all. If either of the 2 input disables are taken to a logic high level, the Q outputs are fed back to the inputs, forcing the flip-flops to remain in datahseet same state. The outputs are placed in the 3-stage mode when either of the.

Data—Enable Controls, are entered into the flip—flops on the.

When both controls are low, the device outputs display the data in the flip—flops. When either or both of the Output Enable Controls lc high, the Q outputs of the device are in the high—impedance state. Output Enable Control inputs. When either or both of the. Home – IC Supply – Link.

During 3—state operation, these outputs assume a high— impedance state.

A high level on this pin resets all datasheft and forces the Q outputs low, if they are not already in high—impedance state. When both Data Enable Controls are low, data at the D inputs are loaded into the flip—flops with the rising edge of the Clock input. Clearing is enabled by taking the clear input to a logic.

During 3—state operation, these outputs assume a high—. When either M or N or both is are high the output is disabled to the high-impedance state; however sequential operation of the flip-flops is not affected.

Output Enable Controls are high, the Q outputs of the device. The outputs are placed in the 3-stage mode when either of the output disable pins are in the logic high level.

During normal operation of the. Data on these pins, when enabled by the Data—Enable Controls, are entered into the flip—flops on the rising edge of the clock.

Active—low Data Enable Control inputs. The 3-state outputs allow the device to be used in bus organized systems. The data outputs change state on the positive dataheet edge of the clock.

The 3-state outputs allow the. Clearing is enabled by taking the clear input to a logic high level. When either or both of these controls are high, there is no change in the state of the flip—flops, regardless of any changes at the D or Clock inputs.

The four D type Flip-Flops operate synchronously from a common clock. Enable Controls are low, data at the D inputs are loaded into. When both controls are. If either of the 2 input disables are taken to a datahseet high level, the Q outputs are fed back to the inputs.

During normal operation of the device, the outputs of the D flip—flops appear at these pins. When either M or N or both is are high the output is disabled to the high-impedance state.
