74HC93 4-Bit Binary Ripple Counter IC SOIC-14 Package
The 74HC93 are high-speed silicon-gate CMOS devices and are pin-compatible with low-power Schottky TTL (LSTTL). These 4-bit binary ripple counters consist of four master-slave flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has a separate clock input (CP0 and CP1) to initiate state changes of the counter on the HIGH to LOW clock transition. State changes of the Qn outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and should not be used for clocks or strobes. A gated AND asynchronous master reset (MR1 and MR2 is provided which overrides both clocks and resets (clears) all flip-flops. Because the output from the divide by two sections is not internally connected to the succeeding stages, the device may be operated in various counting modes. In a 4-bit ripple counter, the output Q0 must be connected externally to input CP1. The input count pulses are applied to clock input CP0. Simultaneous frequency divisions of 2, 4, 8, and 16 are performed at the Q0, Q1, Q2, and Q3 outputs as shown in the function table. As a 3-bit ripple counter, the input count pulses are applied to input CP1. Simultaneous frequency divisions of 2, 4, and 8 are available at the Q1, Q2, Q3 outputs. Independent use of the first flip-flop is available if the reset function coincides with the reset of the 3-bit ripple-through counter. This product is known as 74HC93 4-Bit Binary Ripple Counter IC,74HC93 4 Bit Binary Ripple Counter IC, 74HC93 Counter IC,74HC93 Ripple Counter IC, CD74HC93M96, CD74HC93M, CD74HC93EE4, CD74HC93E, CD74HC93MT, CD74HCT93E.
