The ON Semiconductor MM74HC393MX is a dual 4-bit ripple carry binary counter. It utilizes advanced silicon-gate CMOS technology and can be cascaded to create a single divide-by-256 counter. Each of the two 4-bit counters increments on the HIGH-to-LOW transition of the clock input and features an independent clear input for count truncation and divide-by-N configurations.
Key electrical specifications include a wide operating supply voltage range of 2V to 6V and a typical operating frequency of 50 MHz. The device also exhibits low input current (<1 µA) and low quiescent supply current (80 µA maximum). The typical propagation delay from clock to output QA is 13 ns. Each counter output can drive 10 low power Schottky TTL equivalent loads.
This counter is housed in a 14-SOIC surface mount package. It operates within an ambient temperature range of -40°C to 85°C. The asynchronous reset function allows for flexible counter implementation. All inputs are protected against static discharge.
