The SN74HC241DWE4 is a 4-bit bus transceiver with tri-state output and enable control. It is one of Texas Instruments\' popular buffer/line driver devices, specially designed for logic interface between A/D converters, digital systems, and high-speed busses. It is based on the original design of the SN54HC241, but with an improved low-voltage specification, allowing operation down to 2V.

This device is part of the Texas Instruments (TI) 74HC logic family, which provides higher speed than the standard 74LS and 74F logic ICs. All ICs in this family are specifically designed to be used with MCUs and MCS instead of TTL-level logic, as well as with high-speed communications and data acquisition systems. All of them are constructed using CMOS and BiCMOS, so they are tolerant of voltage spikes up to seven times the power supply voltage.

Application Field

The SN74HC241DWE4 is primarily used as an interface between a digital system and an analog system, such as an A/D converter. It can also be used in switching applications and in digital communication applications. It is ideal for use in applications that require high speeds and require few additional components. It also has excellent ESD protection for sensitive devices. The SN74HC241DWE4 is also suitable for use in low-power and low-voltage applications.

Working Principle

The SN74HC241DWE4 is a 4-bit bus transceiver with tri-state output and enable control. It is capable of transferring data in both directions between two buses. It has four input data pins, two output enable pins, one active low chip enable pin, and an active low output enable pin. The four data pins are used in both directions to transfer data. The two output enable pins are used to control the direction of data flow. The active low chip enable pin is used to enable or disable the chip. The active low output enable pin is used to put the outputs into a high-impedance state.

The SN74HC241DWE4 can operate up to a maximum frequency of 25 MHz and is typically used for high-speed data transmission. The input and output buffers on the IC are designed for low-voltage and low-power applications. It also has a low noise level and a low propagation delay. The IC supports multiple supply voltages from 2V to 7V and is available in both surface-mount and through-hole packages.

In summary, the SN74HC241DWE4 is a reliable, high-speed buffer/line driver that provides an ideal interface between digital and analog systems. It offers excellent ESD protection, low-power and low-voltage operation, and is suitable for use in a variety of applications.
