The SN74ABT2245PW has a total of 20 pins, which are arranged as follows:
Advantages: - Allows seamless communication between devices operating at different voltage levels - Supports bidirectional data transfer - Provides automatic direction control and output enable features - Compatible with both TTL and CMOS logic families - High-speed operation enables efficient data transmission
Disadvantages: - Limited to a supply voltage range of 4.5V to 5.5V - May require additional components for level shifting in certain applications - Not suitable for applications requiring higher data rates
The SN74ABT2245PW is designed to translate signals between two independent buses operating at different voltage levels. The direction of data flow is controlled by the DIR pin, which determines whether the data is transmitted from Channel A to Channel B or vice versa. The output enable pins (OE) allow individual channels to be enabled or disabled as needed.
When the DIR pin is set to transmit data from Channel A to Channel B, the inputs on Channel A are translated to the voltage level of Channel B and appear on the corresponding outputs. Similarly, when the DIR pin is set to transmit data from Channel B to Channel A, the inputs on Channel B are translated to the voltage level of Channel A and appear on the corresponding outputs.
The SN74ABT2245PW finds application in various fields where voltage-level translation is required. Some of the common application areas include:
These alternative models offer similar functionality to the SN74ABT2245PW but may have different characteristics, specifications, or package options.
