Логическая ИС SN74ACT1073DW

16-битный массив согласования шины с функцией удержания , 4.5В до 5.5В, SOIC-20

The SN74ACT1073DW is a 16-bit Bus Termination Network with bus hold function. It is designed to terminate bus lines in CMOS systems. The integrated low-impedance diodes clamp the voltage of undershoots and overshoots caused by line reflections and ensure signal integrity. The device also contains a bus-hold function that consists of a CMOS-buffer stage with a high-resistance feedback path between its output and its input. The SN74ACT1073 prevents bus lines from floating without using pull-up or pull-down resistors. The high-impedance inputs of these internal buffers are connected to the input terminals of the device. The feedback path on each internal buffer stage keeps a bus line tied to the bus holder at the last valid logic state generated by an active driver before the bus switches to the high-impedance state.
