DESCRIPTION
The 74ABT16821A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
   
FEATURES
• 20-bit positive-edge triggered register
• Multiple VCC and GND pins minimize switching noise
• Live insertion/extraction permitted
• Power-up reset
• Power-up 3-State
• 74ABTH16821A incorporates bus-hold data inputs which
    eliminate the need for external pull-up resistors to hold unused
    inputs
• Output capability: +64mA/-32mA
• Latch-up protection exceeds 500mA per JEDEC Std 17
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
    and 200V per Machine Model
