74ABT241PW,112

The 74ABT241PW,112 is a logic circuit belonging to the category of Buffers, Drivers, Receivers, Transceivers. This part is a low voltage, low power transceiver that operates from a single 2.5 volt supply. It features two low current outputs which allow for a wide variety of peripheral circuitry.

The 74ABT241PW,112 consists of two non-inverting buffers, and two inverting buffers. It has an output enable which, when enabled, will drive the outputs with the low voltage logic levels specified. When disabled all outputs are forced to a high impedance, resulting in a low current requirement. The select input sets the direction of data flow: when enabled, data is transferred from the A inputs to the B outputs; when disabled, data is transferred from the B inputs to the A outputs.

This device is widely used in digital systems with low power budgets or in systems where the power supply tends to fluctuate. Examples include: communication controllers, remote data acquisition systems, portable systems, and bus interface controllers, etc.

The part can be used as either a 1-to-1, single-ended (Example 1) or a 2-to-1, differential (Example 2) transceiver. In both configurations, the basic circuit is the same. The select input determines the data flow direction and the output enable controls the outputs. Both examples start with a logic signal applied at one of the inputs (A1 or B1). In Example 1, the output enable and the select inputs are both asserted which results in the data being transferred directly from the A1 input to the B1 output. Example 2 is identical except for two additional considerations. First, dual inputs (A1 and A2) and dual outputs (B1 and B2) are required. Second, the select input must be enabled in order to properly couple the A1 and A2 inputs to the B1 and B2 outputs.

This part can also be used as a differential line driver. The 74ABT241PW,112 can be used to provide isolated differential outputs on a wide range of logic systems. In this configuration, the device provides a low power version of a 9-bit differential line driver. The 9-bit output is driven via the differential A and B outputs, with the data source being the differential selection inputs (A1/A2 and B1/B2). The output enable is used as the enable for the full-duplex line driver.

All inputs are TTL compatible. The 74ABT241PW,112 can interface directly with a variety of TTL, LVTTL and CMOS inputs. Most inputs are also Schmitt triggers and therefore, the device can reliably, and accurately, interpret input waveforms with varying rise and fall times.

The 74ABT241PW,112 offers many advantages over other logic circuits. It consumes a low amount of power and can operate with a single 2.5 volt supply, allowing it to be used in portable and battery operated systems. It also has low input-to-output skew, which is ideal for use in high-speed applications. Moreover, it has a wide range of functional capabilities and can be used in a variety of digital systems.

The 74ABT241PW,112 is a versatile logic circuit which is suitable for a range of digital systems. By combining the functionality of the dual buffer, dual inverter and differential drivers, this part provides a simple and effective solution for low voltage, low power applications.
