74LVT162374
3.3 V 16-bit edge-triggered D-type flip-flop with 30
Ω
termination resistors; 3-state
Rev. 03 — 17 January 2005
Product data sheet
1. 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
Ω
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.
