SN74ABT2241DW Application Field and Working Principle

The SN74ABT2241DW is a low-power low-voltage bi-directional translator from Texas Instruments. The device is designed to increase system speed while reducing system voltage and power consumption. It can design a high-performance logical channel between two systems with different logic families. The SN74ABT2241DW is an integrated 10-channel translator with no latch-up problem. This product increases the system speed by providing faster output responses. The device has separate input and output buffers that reduce the capacitance to increase the transfer rate.

Application Field

The device is suitable for advanced system applications that require high-performance switching and fast outputs. In many electronic systems, the voltage levels used to drive different logic devices can vary. The SN74ABT2241DW is ideal in applications where devices with different voltage levels need to communicate. It is used for TTL-to-CMOS, CMOS-to-TTL, LVTTL-to-LVTTL, and translations of other logic families. It is ideal for portable applications, multimedia products, digital recording, and image processing systems.

Working Principle

SN74ABT2241DW works on the basic working principle of bi-directional translation. It combines the features of a buffer and translator to drive signals between two systems with different logic families. The device has two banks of buffer inputs labelled I0-I9. It also has two banks of buffered outputs labelled O0-O9. Both the input and output buffers are elastically buffered for relatively low propagation delay and fast transitions. The SN74ABT2241DW operates from a single +3.6V to +5.5V power supply with a 0.4V to 3.6V VCCA supply and a 0.8V to 3.6V VCCY supply. Its bi-directional switching circuits are controlled by the outputs of two FET-powered circuits. The first circuit is an ELUS004A-style input, which provides balanced logic-level control over all eight open-collector outputs. The second circuit is an open-collector TL494-style output, which provides a logic-level control of the ELUS004A-style output. The device also features multiple channel enable inputs, which allow the user to enable or disable different channels individually. The enable inputs can be used to implement logic functions such as decoder and encoder logic. The SN74ABT2241DW has an adjustable output slew rate, allowing it to adapt quickly to different logic families. This enables fast and accurate logic conversions. The device also features an adjustable rise and fall times that eliminate glitches. Outputs are protected from over-voltage, due to the included OVCC sense circuits. In summary, the SN74ABT2241DW is a low-power, low-voltage bi-directional translator from Texas Instruments. It is designed to increase system speed while reducing system voltage and power consumption. The device can be used for TTL-to-CMOS, CMOS-to-TTL, LVTTL-to-LVTTL, and translations of other logic families. It features several enable input, adjustable output slew rate, and adjustable rise and fall time, which eliminates glitches. Overall, the SN74ABT2241DW is an ideal device used in high-performance electronic applications.
