1 / 9 page ©1993 Fairchild Semiconductor Corporation www.fairchildsemi.com 74ACTQ541 Rev. 1.6.0 December 2007 74ACTQ541 Quiet Series Octal Buffer/Line Driver with 3-STATE Outputs Features ■ ICC and IOZ reduced by 50% ■ Guaranteed simultaneous switching noise level and dynamic threshold performance ■ Guaranteed pin-to-pin skew AC performance ■ Inputs and outputs on opposite sides of package for easy board layout ■ Non-inverting 3-STATE outputs ■ Guaranteed 4kV minimum ESD immunity ■ TTL compatible inputs ■ Outputs source/sink 24mA General Description The 74ACTQ541 is an octal buffer/line driver designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. This device is similar in function to the 74ACTQ244 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes this device especially useful as an output port for micro- processors, allowing ease of layout and greater PC board density. The 74ACTQ541 utilizes FACT Quiet Series™ technol- ogy to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO™ output control and undershoot corrector in addition to split ground bus for superior performance. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number. All packages are lead free per JEDEC: J-STD-020B standard.
