It is a low-voltage IC, operating with a supply voltage ranging from 3.0V to 3.6V. Outputs are valid down to VCC = 1.5V and can be disabled with the disable control.

Applications

The PI74LPT16244AE can be used in a variety of applications, including:

• Signal buffering and signal conditioning/isolating
• Controlling signal signal directions and timing
• Isolating signals for signal integrity and EMI protection
• Providing signal level translation and bridging
• Driving and receiving data signals
• High-speed logic buffering for bus applications
• Serdes applications

Working Principle

The PI74LPT16244AE is a 16-bit buffer/driver that has the ability to buffer, repeat, and isolate address/data signals and other mixed-signal inputs. It is capable of operating at speeds up to 500 Mbps and works similarly to a source-type logic gate, with each of its 16 lines able to be individually configured. The device can drive output loads up to 28mA and is ideal for driving multiple loads. The device also has the ability to operate over extended temperature ranges and meets standards for EMI susceptibility.

The PI74LPT16244AE has an input stage that is connected to the output stage and configured to adjust the output high and low level voltages. It also features ESD protection and overvoltage protection on its input and output lines. The input and output levels can be configured to either 3.3 or 5V logic. The device also has a slew-rate control pin that can be used to reduce EMI emissions and reduce power consumption.

The PI74LPT16244AE has several features that help with signal integrity and noise/EMI immunity. It includes on-chip ESD protection and has exceptionally low ground bounce and pin-to-pin skew. It also features integrated power-on reset and power-off reset for ensuring proper operation after system powerup or resets. The device also has an ‘on the fly’ mode for changing input logic levels or reversing the logic output level.

The PI74LPT16244AE is a highly reliable and cost-effective logic-based solution that is suitable for a variety of applications. With its high performance and low-end power requirements, it is ideal for buffering, repeating, and isolating address/data signals as well as EMI and power-supply sensitive circuits. It is also suitable for use in high-speed applications such as bus interfaces, data transmission, and serial links.
