16-bit D-type flip-flop
74ABT16273
74ABTH16273
FEATURES
•
16-bit D-type edge triggered flip-flops
•
Output capability: +64mA/–32mA
•
TTL input and output switching levels
•
Live insertion/extraction permitted
•
Power-up reset
•
74ABTH16273 incorporates bus-hold data inputs which eliminate
the need for external pull-up resistors to hold unused inputs
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.
Two options are available, 74ABT16273 which does not have the
bus-hold feature and 74ABTH16273 which incorporates the
bus-hold feature.
•
Latch-up protection exceeds 500mA per JEDEC Std 17
•
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model

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.

NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
4. This is the bus hold overdrive current required to force the input to the opposite logic state.
