Introduction

74LVCH162373ADGG is a logic latch designed to provide a low-cost solution for data output buffering in a wide range of applications. It is one of the members of the 74LVCH low-voltage CMOS family. Developed to meet the needs of a broad range of applications, the 74LVCH162373ADGG exhibits outstanding parameter uniformity between its multiple sub-devices. This makes it ideal for any device operating at high or low frequency operation. Furthermore, the low-voltage supply voltage, low power consumption, and fully CMOS compatible TTL input levels make it suitable for use in battery-supplied applications.

Technical Specifications

The 74LVCH162373ADGG is a 16-bit registered latch with an output enable (OE) pin. It is a dual-in/single-out type register, with one register on each side, composed of two 8-bit latches with full complement add-on features. Each latch has an output enable pin, and can be enabled separately to control the output of the register in concert with the enable control signals. The flip-flops and the output buffers of the device are provided with separate supply pins, resulting in improved operation under severe voltage drops.The power-supply voltage range is 0.95 V to 3.6 V, and the operating temperature range is 0°C to 70°C. The output drive capacity is 10 LSTTL load, resulting in high noise margin. The input and output logic levels are fully CMOS-compatible TTL levels. The minimum and maximum propagation delays are 0.7 ns and 15 ns, respectively.

Application Field and Working Principle

The 74LVCH162373ADGG is typically used in data transfer systems, such as data bus controllers and buses. It can also be used as a transcoder in I/O, serial communication systems, and other logic systems requiring the conversion of logic levels. It can also be used as a storage register for data processing.The working principle of the 74LVCH162373ADGG is relatively simple. When the input logic level is low, the latch is open and allows data to pass through. When the input logic level is high, the latch is closed, and the data is stored in the register. The data can then be read out of the register when the output enable (OE) pin is enabled.

Conclusion

The 74LVCH162373ADGG is a reliable, low-cost logic latch designed to provide a comprehensive solution for data buffering. It can be used in a wide range of applications, including data transfer systems, serial communication systems, and data processing. The working principle is simple and efficient, making it a great choice for applications that require data buffering.
