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
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
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.
