74ACTQ32
Quiet Series Quad 2-Input OR Gate
General Description
The ACTQ320 contains four, 2-input OR gates and utilizes Fairchild Quiet Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior ACMOS performance.
Features
■ICC reduced by 50%
■Guaranteed simultaneous switching noise level and dynamic threshold performance
■Improved latch-up immunity
■Minimum 4 kV ESD protection
■TTL-compatible inputs
■Outputs source/sink 24 mA

Note 1: Absolute maximum ratings are values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT circuits outside of databook specifications.

Note 8: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH). Parameter guaranteed by design.
