1 / 4 page © 2000 Fairchild Semiconductor Corporation DS006388 www.fairchildsemi.com August 1986 Revised March 2000 DM74LS126A Quad 3-STATE Buffer General Description This device contains four independent gates each of which performs a non-inverting buffer function. The outputs have the 3-STATE feature. When enabled, the outputs exhibit the low impedance characteristics of a standard LS output with additional drive capability to permit the driving of bus lines without external resistors. When disabled, both the output transistors are turned OFF presenting a high-imped- ance state to the bus line. Thus the output will act neither as a significant load nor as a driver. To minimize the possi- bility that two outputs will attempt to take a common bus to opposite logic levels, the disable time is shorter than the enable time of the outputs. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
