This pulse can be used to enable the next cascaded stage. All referenced brands, product names, service names and trademarks product for such automotive applications, use and specifications, and b are the property of their respective owners.

Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock CP. Functional diagram Fig 2.

Functional description Dqtasheet 3. Customers should provide appropriate shall an agreement be valid in which the NXP Semiconductors product is design and operating safeguards to minimize the risks associated with their deemed to offer functions and qualities beyond those described in the applications and products.

NXP does not accept any liability in this respect. Log In Sign Up. The look-ahead carry simplifies serial cascading of the counters.

It causes the data at the data inputs D0 to D3 to be loaded into the counter on the positive-going edge of the clock. Help Center Find new research papers in: Revision history Table Ordering information Table 1.

The latest product status information is available on the Internet at URL http: Recommended operating conditions Table 5.

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

Product data sheet Rev. Contents 1 General description.


Dynamic characteristics Table 7. Measurement points are given in Table 8. All counters are reset with a low level on the Master Reset input, MR.

Constant or profits, lost savings, business interruption, costs related to the removal or repeated exposure to limiting values will permanently and irreversibly affect replacement of any products or rework charges whether or not such the quality and reliability of the device.

In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met.

This TC pulse is used to enable the next cascaded stage.
