74ACT16543DLRG4 Integrated Circuit by Texas Instruments

The 74ACT16543DLRG4 is a high-performance, integrated circuit designed and manufactured by Texas Instruments, a leader in the semiconductor industry. This IC is part of the 74ACT series, known for its advanced CMOS logic technology which combines the speed of NMOS with the low power consumption of CMOS. The 74ACT16543DLRG4 is specifically a 16-bit transparent D-type latch with 3-state outputs, making it an ideal choice for temporary data storage and transfer operations in computing and digital systems.

With its wide operating voltage range of 4.5V to 5.5V, the 74ACT16543DLRG4 is versatile and can be used in various applications that require a robust and reliable logic interface. It is characterized for operation from -40°C to 85°C, ensuring functionality across a broad spectrum of temperature conditions, which is critical for industrial and automotive applications.

The device features two separate sections, each with 8 bits. Each section can be controlled independently by the latch enable (LE) and output enable (OE) inputs, providing designers with flexibility in managing data flow. When the latch enable input is high, the Q outputs follow the data (D) inputs. If the latch enable input is taken low, the Q outputs are latched at the levels set up at the D inputs.

The 74ACT16543DLRG4 also boasts 3-state outputs, which means that the outputs can be set to one of three conditions: logical high, logical low, or high impedance. The high impedance state is particularly useful when the outputs are not needed, as it minimizes power consumption and prevents bus contention by effectively removing the device from the bus line.

Encased in a 48-pin LSSOP (Low Profile Small-Outline Package), the 74ACT16543DLRG4 has a compact footprint that is suitable for space-constrained applications. Its packaging is designed for optimal heat dissipation and reliability, ensuring consistent performance even under strenuous conditions.

In summary, the Texas Instruments 74ACT16543DLRG4 is a powerful and reliable component for designers seeking a high-speed and low-power solution for data storage and bus interface applications. Its robust feature set and flexible design make it an excellent choice for a wide range of digital logic systems.
