FEATURES
16-bit bus interface
3-State buffers
Output capability: +64mA/-32mA
TTL input and output switching levels
Input and output interface capability to systems at 5V supply
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
Live insertion/extraction permitted
Power-up 3-State
74ABTH16240A 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 74ABT16240A is a high-performance BiCMOS device which
combines low static and dynamic power dissipation with high speed
and high output drive.
This device is an inverting 16-bit buffer that is ideal for driving bus
lines. The device features four Output Enables (1OE, 2OE, 3OE,
4OE), each controlling four of the 3-State outputs.
Two options are available, 74ABT16240A which does not have the
bus hold feature and 74ABTH16240A which incorporates the bus
hold feature.
