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

Actually, is it reversible at all? Post as a guest Name. You either have to invert the outputs using an additional device or use a different counter.
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.
Counting and parallel presetting are both accomplished synchronously with the negative-to-positive transition of the clock.

The ‘HC and ‘HCT are asynchronous reset decade and binary counters, respectively; the ‘HC and ‘HCT devices are decade and binary counters, respectively, that dwtasheet reset synchronously with the clock. This TC pulse is used to enable the next cascaded stage. Margin,quality,low-cost products with low minimum orders.

This device only counts up. In the ‘HC and ‘HCT counters synchronous reset typesthe requirements for setup and hold time with respect to the clock must be met. The look-ahead carry feature simplifies serial datasgeet of the counters. I have one question on the 74HC synchronous counter, you can find the datasheet here: Freight and Payment Recommended logistics Recommended bank.
You could re-interpret the outputs as negative active low logic.
