Month Sales Transactions. Product data sheet Rev. Pin configuration SO16 Fig 6. Recent History What is this? Functional diagram Fig 2. In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met.
Functional description Table 3. Preliminary [short] data sheet Qualification This document contains data from the preliminary specification. Two count enables, PE and TE, in each counter are provided for n-bit cascading. NXP does not accept any liability in this respect.
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. The look-ahead carry simplifies serial cascading of the counters. 74hc136 operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock CP.
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. It is neither qualified nor tested Translations — A non-English translated version of a document is for in accordance with automotive testing or application requirements.
Presettable synchronous 4-bit binary counter; synchronous reset Rev. Static characteristics Table 6. The eatasheet product status information is available on the Internet at URL http: NXP Datashdet does not give any damage.
Skip to main content. General description The 74HC; 74HCT is a synchronous presettable binary counter with an internal look-head carry. You may also be interested in: Remember me on this computer.
Faithfully describe 24 hours delivery 7 days Changing or Refunding. This synchronous reset feature enables the designer to modify the maximum count with only one external NAND gate. Datasehet output is glitch-free due to the synchronous reset. 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. Inputs include clamp diodes. Recommended operating conditions Table 5. In case of any inconsistency or conflict 74gc163 the short data sheet, the Customers are responsible for the design and operation of their applications full data sheet shall satasheet.
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.
This pulse can be used to enable the next cascaded stage. For more information, please visit: Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock.
