Philips Semiconductors
16-bit buffer/driver (3-State)
Product specification
74ABT16241A
74ABTH16241A
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
• 74ABTH16241A 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 74ABT16241A is a high-performance BiCMOS device which
combines low static and dynamic power dissipation with high speed
and high output drive.
This device is a 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, 74ABT16241A which does not have the
bus hold feature and 74ABTH16241A which incorporates the bus
hold feature.
