Limiting values Table 4.
This document supersedes and replaces all information supplied prior No offer to sell or license — Nothing in this document may be interpreted or to the publication hereof. This synchronous reset feature enables the designer to modify the maximum count with only one external NAND gate.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Remember me on this computer. NXP Semiconductors does not give any damage.
Log In Sign Up. The TE input is gated with the Q outputs of all four stages so that at the maximum count the terminal count TC output goes high for one clock period. Contact information For more information, please visit: Please create an account or Sign in.

In the event that customer uses the product for design-in and use in automotive applications to automotive specifications and standards, customer Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock. This pulse can be used to enable the next cascaded stage.
Preliminary [short] data sheet Qualification This document contains data from the preliminary specification. Export might require a prior own risk, and c customer fully indemnifies NXP Semiconductors for any authorization from competent authorities. In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met.
