INTEGRATED CIRCUITS 74ABT162244 74ABTH162244 16-bit buffer/line driver with 30Ω series termination resistors (3-State) Product specification Supersedes data of 1998 Feb 25 IC23 Data Handbook 1998 Oct 22 Philips Semiconductors Product specification 16-bit buffer/line driver with 30Ω series termination resistors (3-State) FEATURES 74ABT162244 74ABTH162244 PIN CONFIGURATION • 16-bit bus interface • Multiple VCC 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 30Ω 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. 1OE 1 48 2OE 1Y0 2 47 1A0 1Y1 3 46 1A1 GND 4 45 GND 1Y2 5 44 1A2 1Y3 6 43 1A3 VCC 7 42 VCC 2Y0 8 41 2A0 2Y1 9 40 2A1 GND 10 39 GND 2Y2 11 38 2A2 2Y3 12 37 2A3 3Y0 13 36 3A0 3Y1 14 35 3A1 GND 15 34 GND 3Y2 16 33 3A2 3Y4 17 32 3A3 VCC 18 31 VCC 4Y0 19 30 4A0 4Y1 20 29 4A1 GND 21 28 GND 4Y2 22 27 4A2 4Y3 23 26 4A3 4OE 24 25 3OE SA00013 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.

Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
