2 / 11 page Philips Semiconductors Product specification 74ABT162827A 74ABTH162827A 20-bit buffer/line driver, non-inverting, with 30 W termination resistors (3-State) 2 1998 Feb 27 853-1928 19025 FEATURES • Multiple V CC and GND pins minimize switching noise • Live insertion/extraction permitted • 3-State output buffers • Power-up 3-State • 74ABTH162827A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs • Output capability: +64mA/-32mA • 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 DESCRIPTION The 74ABT162827A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT162827A 20-bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NOR Output Enables (nOE1, nOE2) for maximum control flexibility. The 74ABT162827A is designed with 30 W series resistance in both the pull–up and pull–down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters. Two options are available, 74ABT162827A which does not have the bus-hold feature and 74ABTH162827A which incorporates the bus-hold feature.
