SN74LV11ADBR

Introduction

The SN74LV11ADBR is a logic gate, inverter and buffer IC (Integrated Circuit) manufactured by Texas Instruments. It is a high-speed Dual 4-Input AND Gate. The SN74LV11ADBR combines advanced CMOS logic levels (low power, high noise immunity, and high speed) into a 14-pin package. The AND gate and inverter are designed to operate with inputs ranging from 1.65V to 3.6V and has an output that is capable of driving up to 32mA and a fan-out of 10 LSTTL loads. The SN74LV11ADBR provides all of the advantages of the expanding market of low voltage logic devices while continuing to support the demanding requirements of hard, real-time system architectures.

Functionality and Features

The SN74LV11ADBR is a logic gate, inverter, and buffer IC. It is an enhanced version of the SN74LS family of logic gates. The SN74LV11ADBR provides a total of four actively driven inputs and four active outputs for each of the two gates and two inverters. The inputs are guaranteed to be compatible with standard CMOS or LSTTL logic levels. The active low enables, EN1\EN2 and EN3\EN4, can be used to disable the outputs when logic "0" is applied to the enable pin. Each of the four gates provide single drive outputs. Additionally, the SN74LV11ADBR provides internal Schmitt Trigger action at all inputs which provides the necessary hysteresis for Switch Debouncing. There is an output enable pin that can be used to disable either one or both of the outputs. The SN74LV11ADBR provides ultra low active (input) and standby power dissipation.

The SN74LV11ADBR is designed for use in many high-speed, high-density applications such as line powering, logic buffering, and waveform generation. With such a wide array of uses, the SN74LV11ADBR provides a complete, versatile and cost-effective solution for a variety of applications. The SN74LV11ADBR features a 14-pin package and has an operating temperature range of 0-70°C. Logic "1" Inputs on all four channels provide the highest noise immunity when the part is used in a switching circuit.

Application Field and Working Principle

The SN74LV11ADBR is well-suited for a wide range of applications, with its four actively driven inputs and four active outputs for each of the two gates and two inverters. Its low power consumption and high speed make it ideal for many digital systems, including line powering and waveform generation. The SN74LV11ADBR can also be used for logic buffering, effectively extending the range and speed of logic signals from the source logic.
The SN74LV11ADBR is a logic IC comprised of two independent four-input AND gates and two complementary inverters. The logic gates have four inputs (A, B, C and D) and one output (Y). The inverters have a single input (X) and one output (Z). When all four inputs to the AND gate are at logic "1" (high), the output will be at logic "1". If one or more of the inputs is at logic "0" (low), the output will be at logic "0". The inverter simply reverses the logic level, so that when the input is at logic "1", the output is at logic "0".

Conclusion

The SN74LV11ADBR is a very versatile high-speed Dual 4-Input AND Gate and inverter IC manufactured by Texas Instruments. It provides many of the advantages of the expanding market of low voltage logic devices while supporting the real-time system architectures. The SN74LV11ADBR is well suited for a variety of applications, including line powering, logic buffering and waveform generation. It provides active low enables, Schmitt trigger action, and an output enable pin. With its low power consumption, high noise immunity and wide operating temperature range, the SN74LV11ADBR is a great choice for logic buffering applications.
