The 74ABT16541 and 74ABTH16541 are 16-bit buffers/line drivers with 3-State functionality, produced by Philips Semiconductors. The product has low static and dynamic power consumption, high speed and high output drive. Its output can absorb 64mA current and output 32mA current. The product has two options, 74ABT16541 does not have the bus hold feature, and 74ABTH16541 has the bus hold feature.
This datasheet describes the Philips 74ABT16541 and 74ABTH16541, high-performance BiCMOS devices designed as 16-bit buffers and line drivers. These devices combine low static and dynamic power dissipation with high speed and high output drive, making them ideal for driving bus lines in microprocessor systems. The 74ABT16541 offers standard 3-State outputs, while the 74ABTH16541 incorporates bus-hold data inputs to eliminate the need for external pull-up resistors.
