产品概述
This device 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 SN74ACT1071 prevents bus lines from
floating without using pullup or pulldown 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.The SN74ACT1071 is characterized for operation from -40°C to
85°C.
