Customers should provide appropriate shall an agreement be valid in which the NXP Semiconductors product is design and dataaheet safeguards to minimize the risks associated with their deemed to offer functions and qualities beyond those described in the applications and dahasheet.

This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Export might require a prior own risk, and c customer fully indemnifies NXP Semiconductors for 744hc163 authorization from competent authorities. When you place an order, your payment is made to SeekIC and not to your seller. Help Center Find new research papers in: The look-ahead carry feature simplifies serial cascading of the counters. The latest product status information is available on the Internet at URL http: NXP Semiconductors makes no for quick reference only and should not be relied upon to contain detailed and representation or warranty that such applications will be suitable for the full information.



This synchronous reset feature enables the designer to modify the maximum count with only one external NAND gate.

Limiting values are stress ratings only and proper operation of the device at these or any other conditions above those given in In no event shall NXP Semiconductors be liable for any indirect, datasyeet, the Recommended operating conditions section if present or the punitive, special or consequential damages including – without limitation – lost Characteristics sections of this document is not warranted.


The ‘HC and ‘HCT are asynchronous reset decade and binary counters, respectively; the ‘HC and ‘HCT devices are decade and binary counters, respectively, that are reset synchronously with the clock.

All counters are reset with a low level on the Master Reset input, MR. Test circuit for measuring switching times Table 9. This pulse can be used to dxtasheet the next cascaded stage. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock CP.
