74hc Counter ICs are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 74hc Counter ICs. The M54/74HC/ are BCD Decade counters and the M54/74HC/ are 4 bit binary counter- s. The CLOCK input is active on the rising edge.

Sign up using Email and Password. The TE input is gated with the Q outputs of all datashete stages so that at the maximum count the terminal count TC output goes high for one clock period. This device only counts up.
This TC pulse is used to enable the next cascaded stage. You may also be interested in: Sign up using Facebook. You could re-interpret the outputs as negative active low logic.

The look-ahead carry feature simplifies serial cascading of the counters. 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 datadheet clock.
Email Required, but never shown. Sign up or log in Sign up using Google. The HC is an up counter.
When you place an order, your payment is made to SeekIC and not to your seller. SeekIC only pays the seller after confirming you have received your order. Martin Nikovski 24 3.
Depending on what you are doing, this mind flip will often work. Faithfully describe 24 hours delivery 7 days Changing or Refunding. In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met.

I have one question on the 74HC synchronous counter, you can find the datasheet here: Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock. You either have to invert the outputs using an additional device or use a different counter.
