General description
The 74LVT162374 is a high performance BiCMOS product designed for V
CC
operation at
3.3 V.
The 74LVT162374 is designed with 30
series resistance in both the HIGH and LOW
states of the output. This design reduces line noise in applications such as memory
address drivers, clock drivers, and bus receivers/transmitters.
This device is a 16-bit edge-triggered D-type flip-flop featuring non-inverting 3-state
outputs. The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the
positive transition of the clock (CP), the Q outputs of the flip-flop take on the logic levels
set up at the D inputs.
