The ST7538P013TR is a high-performance, low-power 8-bit I/O port buffer, a general-purpose bus driver, and a line receiver. It is an integrated logic circuit specially designed for the interface of peripheral circuits, computer systems, and other electronic devices. It is application-specific integrated circuits (ASICs) that can be used in a variety of applications. This paper will discuss the application field and working principle of the ST7538P013TR.

The ST7538P013TR has three active-low control inputs, nOE, nWE and nCE, and eight I/O of TTL/CMOS drivers. It is suitable for a wide range of applications, such as driving device peripherals, low-power signal transmission, cascaded data and address buses, memory access circuits, and microprocessor-controlled systems. This chipset is designed to provide a low-power solution, with a total input and output current of only 20 ma and a quiescent standby current of 1.2ma. It is also designed with a low noise level and a wide signal swing, making it ideal for precise system transmissions.

The working principle of ST7538P013TR uses the low activation fields of nOE, nWE and nCE to control the output data bus. The active low control pins can be used activate the output by enabling the reset circuitry, while the input pins (D0-D7) can be used to supply data. The reset function is enabled when all three active-low control inputs (nOE, nWE and nCE) are in a low state. When the control pins are in a low state, the reset circuit is activated, and the output pins are reset to a low state. When the active-low control pins are in a high state, data on the input pins (D0-D7) is transmitted to the output pins, thereby driving the peripheral circuitry. The nWE and nCE control lines can be used together to provide a higher data output rate.

The ST7538P013TR is designed for a wide range of applications, including microprocessor-controlled systems, peripheral and signal transmission circuitry, memory access circuits, cascaded data and address buses and low power components. Its active-low control inputs provide a simple, yet highly effective means of controlling signal transmissions. Its low noise level and wide signal swing make it suitable for data transmission and precise system transmissions. Its low-power solution makes it an ideal choice for low-power applications. Its integrated logic circuit simplifies circuit design and reduces board space.

In summary, the ST7538P013TR is a low-power, high-performance 8-bit I/O port buffer and bus driver. It is designed for a variety of applications, providing a low-power solution with minimal noise and wide signal swing for precise system transmissions. Its active-low control inputs provide a simple and effective means of controlling signal transmissions. Its integrated logic circuit ensures ease of circuit design and reduces board space. In short, this chipset provides the perfect solution for a variety of interface, driver, receiver, and transceiver applications.
