2 / 10 page Philips Semiconductors Product specification 74ABT16244A 74ABTH16244A 16-bit buffer/line driver (3-State) 2 1998 Oct 07 853-1769 20143 FEATURES • 16-bit bus interface • Multiple V CC and GND pins minimize switching noise • Power-up 3-State • 3-State buffers • Output capability: +64 mA/–32mA • Live insertion/extraction permitted • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model • 74ABTH16244A incorporates bus hold data inputs which eliminate the need for external pull up resistors to hold unused inputs • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs DESCRIPTION The 74ABT16244A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT16244A 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, 74ABT16244A which does not have the bus hold feature and 74ABTH16244A which incorporates the bus hold feature.
