74LVT16374A; 74LVTH16374A
3.3 V 16-bit edge-triggered D-type flip-flop; 3-state
Rev. 10 — 2 April 2012
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.
2. Features and benefits
16-bit edge-triggered flip-flop
3-state buffers
Output capability: +64 mA and
32
mA
TTL input and output switching levels
Input and output interface capability to systems at 5 V supply
Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused
inputs
Live insertion and extraction permitted
Power-up reset
Power-up 3-state
No bus current loading when output is tied to 5 V bus
Latch-up protection:
JESD78B Class II exceeds 500 mA
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V

(1) This is not a supply pin, the substrate is attached to this pad using conductive die attach material. There is no electrical or
mechanical requirement to solder this pad however if it is soldered the solder land should remain floating or be connected to
GND.
