2 / 10 page  Philips Semiconductors Product specification 74ABT162244 74ABTH162244 16-bit buffer/line driver with 30 Ω series termination resistors (3-State) 2 1998 Oct 22 853-1773 20224 FEATURES • 16-bit bus interface • Multiple V CC and GND pins minimize switching noise • Power-up 3-State • 3-State buffers • Output capability: +12 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 • Same part as 74ABT162244-1 • 74ABTH162244 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 74ABT162244 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT162244 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. The 74ABT162244 is designed with 30 Ω series resistance in both the upper and lower output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters. The 74ABT162244 is the same as the 74ABT16244-1. The part number has been changed to reflect industry standards. Two options are available, 74ABT162244 which does not have the bus hold feature and the 74ABTH162244 which incorporates the bus hold feature.
