The SN74HC393DBR from Texas Instruments is a dual 4-bit binary counter integrated circuit. This device contains eight flip-flops and additional gating to implement two individual 4-bit counters within a single package. It is designed for a wide operating voltage range of 2V to 6V, making it versatile for various applications.
The counter features a typical propagation delay of 13ns and a maximum count rate of 36 MHz. It supports asynchronous reset and negative edge triggering. The outputs can drive up to 10 LSTTL loads, and it offers ±4mA output drive at 5V. With low power consumption (80μA max ICC) and low input current (1μA max), it is suitable for power-sensitive designs.
This component is housed in a 14-SSOP surface-mount package with a body size of 6.2 mm x 7.8 mm. The operating temperature range is -40°C to 85°C. The SN74HC393DBR can significantly improve system densities by reducing the counter package count by 50%.
Key electrical characteristics include a wide operating voltage range, low power consumption, and a typical propagation delay of 13ns. The dual 4-bit counters have individual clocks and direct clears, offering flexibility in design.
