Product specication
Dual D-type ip-op with set and reset; positive-edge
trigger
74LVC74A
AC CHARACTERISTICS
GND = 0 V; tr =tf ≤ 2.5 ns.
Notes
1. Typical values are measured at VCC = 3.3 V.
2. Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed
by design.
