2 / 10 page Philips Semiconductors Product specification 74ABT16273 74ABTH16273 16-bit D-type flip-flop 2 1998 Feb 27 853-1793 19027 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.
