74LVT16374A; 74LVTH16374A
3.3 V 16-bit edge-triggered D-type flip-flop; 3-state
Rev. 11 — 5 February 2019
Product data sheet
1. General description
The 74LVT16374A; 74LVTH16374A are high performance BiCMOS products designed for V
CC
operation at 3.3 V.
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 (nCP), the nQn outputs of the flip-flop take on the logic levels set up at the nDn inputs.

The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
Above 60 °C the value of P
tot
derates linearly with 5.5 mW/K.
