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. logic diagram, one of ten channels (positive logic) D1 TG 1 VCC 11 VCC 10 GND 3 GND 4 1 2 3 4 5 6 7 14 13 12 11 10 9 8 D1 D2 GND GND D3 D4 D5 D10 D9 D8 VCC VCC D7 D6 D PACKAGE (TOP VIEW) PRODUCTION DATA information is current as of publication date.
