SN74LV393ADR Dual Binary Counter from Texas Instruments

The SN74LV393ADR is a high-performance, dual 4-bit binary counter integrated circuit designed and manufactured by Texas Instruments (TI). This precision device is part of TI's SN74LV family, which is renowned for its low-voltage operation and low power consumption. The SN74LV393ADR is specifically engineered to handle a wide range of applications that require reliable counting operations in digital electronic systems.

Fabricated with advanced silicon-gate CMOS technology, the SN74LV393ADR ensures reduced power dissipation while maintaining high-speed operation. It operates over a voltage range of 2 V to 5.5 V, making it compatible with various logic levels and suitable for interfacing with both TTL and CMOS technologies. This versatility allows designers to incorporate the SN74LV393ADR into a diverse array of electronic products, from consumer electronics to industrial control systems.

Key Features:

• Voltage Range: Operates from 2 V to 5.5 V, accommodating a variety of logic levels.
• High-Speed Operation: Ensures efficient counting with a typical clock frequency of 100 MHz at 5 V.
• Low Power Consumption: Ideal for battery-operated and power-sensitive applications.
• Dual Counter: Features two individual 4-bit binary counters that can be used independently or cascaded for an 8-bit counter.
• Output Capability: Can drive up to 15 LSTTL loads, providing robust output drive capability.
• Package: Offered in an 8-pin SOIC (Small Outline Integrated Circuit) package, suitable for surface-mount technology (SMT).

The SN74LV393ADR is designed with individual clear inputs for each counter, which allows for asynchronous resetting of the counter to zero. The counters advance on the falling edge of the clock signal, providing precise control over the counting sequence. This feature is particularly useful in time-critical applications where accuracy is paramount.

In summary, the SN74LV393ADR from Texas Instruments is a reliable and versatile dual binary counter that combines low power consumption with high-speed operation.
