Presentación del producto (en 100 palabras)

The 74AHC1G79GW,125 operates as a positive-edge triggered D-type flip-flop. The device has three pins for logic: D (data input), CP (clock input), and Q (data output). On each rising edge of the CP signal, the logic level present at the D input is captured by the internal master-slave latch and transferred to the Q output. Between clock edges, changes at the D input do not affect the Q output. The flip-flop has no preset or clear inputs; the initial state after power-on is indeterminate. The device is implemented in CMOS technology with a transmission-gate-based master-slave latch structure. The AHC process provides faster switching than standard HC logic with similar power consumption. The +/-8mA output drive at 5V is sufficient for driving multiple CMOS inputs or a short PCB trace.

Pin Nombre Función
1 D Data input
2 Q Data output
3 GND Suelo
4 CP Clock input (positive-edge triggered)
5 VCC Supply voltage (2V to 5.5V)
  • Clock sync: capture asynchronous input on system clock edge, preventing metastability in multi-clock domain designs
  • Frequency divide: connect Q-bar (inverted Q) to D input for divide-by-2 function at up to 125MHz
  • Debounce: capture switch state on clock edge, eliminating bounce-induced multiple transitions
