The NXP 74ABT16841ADL,112 is a low-power CMOS logic device that combines the four-bit bidirectional Transceiver, Quad-D Register, and Quad-complimenter functions into a single monolithic device. The device has four high-speed non-inverting buffer/drivers (A, B, Y, and Z) which are organized as two independent sets of inverting/non-inverting buffers. The 74ABT16841ADL,112 is designed to provide bidirectional bus interfacing between the data and control buses and the system bus. The device also features CMOS input, output and enable logic for all control inputs and outputs, as well as an enable control for the input and output logic.
