description
The SN54LVC74A dual positive-edge-triggered
D-type flip-flop is designed for 2.7-V to 3.6-V V
CC
operation and the SN74LVC74A dual positive-
edge-triggered D-type flip-flop is designed for
1.65-V to 3.6-V V
CC
operation.
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 is transferred to the outputs on
the positive-going edge of the clock 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 can be changed without
affecting the levels at the outputs.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
The SN54LVC74A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74LVC74A is characterized for operation from –40
°
C to 85
