description

This device contains two independent positive-edge-triggered D-type flip-flops. 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 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 74ACT11074 is characterized for operation from –40°C to 85°C.

This configuration is unstable; that is, it does not
persist when either PRE

inactive (high) level.

†

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. 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.
