This document describes the features and characteristics of the 74ABT16244A and 74ABTH16244A 16-bit buffer/line drivers (3-State).
The Philips 74ABT16244A and 74ABTH16244A are high-performance BiCMOS devices designed as 16-bit buffers ideal for driving bus lines. The 74ABT16244A model features four Output Enables, each controlling four 3-State outputs, while the 74ABTH16244A incorporates bus hold data inputs to eliminate the need for external pull-up resistors. These devices combine low static and dynamic power dissipation with high speed and high output drive capabilities.
