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. Both. 74HC 74HC/HCT; Presettable Synchronous 4-bit Binary Counter; Asynchronous Reset. For a complete data sheet, please also download. The IC

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.
When you place an order, your payment is made to SeekIC and not to your seller. Recent History What is this? Home Questions Tags Users Unanswered.
SeekIC only pays the seller after confirming you have received your order. You either have to invert the outputs using an additional device or use a different counter. Actually, is it reversible at all?
In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met. Sign up using Facebook. I have one question on the 74HC synchronous counter, you can find the datasheet here: You could re-interpret the outputs as negative active low logic.
Freight and Payment Recommended logistics Recommended 74hc116.
Post as a guest Name. The look-ahead carry feature simplifies serial cascading of the counters.
Faithfully describe 24 hours delivery 7 days Changing or Refunding. Please create an account or Adtasheet in. Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock.
The datashfet 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. Depending on what you are doing, this mind flip will often work. We will also never share your payment details with your seller.
