16-bit D-type flip-flop

Product specification

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

• 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.
