This document describes the product specifications and features of the 74ABT16827A and 74ABTH16827A, two 20-bit buffers/line drivers. They feature non-inverting (3-State) outputs, multiple VCC and GND pins to minimize switching noise, live insertion/extraction capability, 3-State output buffers, power-up 3-State, bus-hold data inputs in 74ABTH16827A to eliminate the need for external pull-up resistors, output capability of +64mA/-32mA, latch-up protection exceeding 500mA, and ESD protection exceeding 2000V.
The document provides a product specification for the 74ABT16827A and 74ABTH16827A, which are high-performance BiCMOS devices designed for wide data/address paths or buses carrying parity. These 20-bit buffers offer high speed, high output drive, and low static and dynamic power dissipation. The 74ABTH16827A variant incorporates bus-hold data inputs to eliminate the need for external pull-up resistors.
