2 / 10 page Philips Semiconductors Product specification 74ALVT162827 2.5V/3.3V 20-bit buffer/line driver, non-inverting, with 30 Ω termination resistors (3-State) 2 1998 Feb 13 853-1843 18961 FEATURES • Multiple V CC and GND pins minimize switching noise • 5V I/O Compatible • Live insertion/extraction permitted • 3-State output buffers • Outputs include series resistance of 30Ω making external termination resistors unnecessary • Power-up 3-State • Output capability: +12mA/–12mA • 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 • Bus hold data inputs eliminate the need for external pull-up resistors to hold unused inputs DESCRIPTION The 74ALVT162827 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. It is designed for VCC operation at 2.5V or 3.3V with I/O compatibility to 5V. The 74ALVT162827 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 74ALVT162827 is designed with 30 Ω 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.
