DESCRIPTION
The 74ABT16500C is a high-performance BiCMOS Device which combines low static and dynamic power dissipation with high speed and high output drive.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
Two options are available, 74ABT16500C which does not have the bus-hold feature and 74ABTH16500C which incorporates the bus-hold feature.

FEATURES
• 18-bit bidirectional bus interface
• 3-State buffers
• 74ABTH16500C incorporates bus-hold data inputs which
   eliminate the need for external pull-up resistors to hold unused
   inputs
• Output capability: +64mA/-32mA
• TTL input and output switching levels
• Live insertion/extraction permitted
• Power-up reset
• Power-up 3-State
• Negative edge-triggered clock 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
• Flexible operation permits 18 embedded D-type latches or
   flip-flops to operate in clocked, transparent, or latched modes.
