About this product
Description
The SN74HC93N is a 4-Bit Binary Ripple Counter manufactured by Texas Instruments, housed in a standard 14-pin DIP through-hole package. These high-speed silicon-gate CMOS devices are pin-compatible with low power Schottky TTL (LSTTL) and 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. A gated asynchronous master reset (MR1 and MR2) is provided, which overrides both clocks and resets all flip-flops. Since the divide-by-two section isn't internally connected to the following stages, the device can be operated in various counting modes - by externally connecting output Q0 to input CP1 and applying the input pulses to CP0, the chip performs simultaneous frequency divisions of 2, 4, 8, and 16 at the Q0 - Q3 outputs, giving a full 4-bit ripple counter. It can also be used as a standalone 3-bit ripple counter when needed.
The 74HC93 supports a wide operating voltage range of 2V to 6V, making it flexible for use in both 3.3V and 5V logic systems, unlike its LS-series counterpart which is limited to 5V. This, combined with its low power CMOS design, makes the SN74HC93N a solid choice for frequency division, event counting, and general digital timing circuits in modern low-voltage designs as well as legacy TTL-compatible systems.
