Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use
http://www.nexperia.com
Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use

•
TTL input and output switching levels
•
Live insertion/extraction permitted
•
Power-up reset

DESCRIPTION
The 74ABT16273 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
This part is a 16-bit edge triggered D-type flip-flop with non-inverting
high drive outputs. This device can be used as two 8-bit flip-flops or
one 16-bit flip-flop. When the clock (CP) goes High, the data on the
D inputs is stored and the Q outputs display the stored data.
This device also features a master reset (MR) that resets all
flip-flops to the Low state when MR is set to the Low state.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
