Logic - Buffers, Drivers, Receivers, Transceivers

The 74ABT244CPC is a high performance, low power, 10-bit buffer/driver integrated circuit that is designed for use in applications like digital signal processing, communications, and switch/toggle/crossbar circuits.

Application Field

The versatile 74ABT244CPC is ideal for a variety of applications including but not limited to :

• Data Communications
• Signal Multiplexing/Demultiplexing
• Switch/Toggle/Crossbar Matrix Applications
• Data Bus Interface
• Bus Buffer
• Serial Interface
• Clock Buffering
• High-Speed Translators/Drivers

The 74ABT244CPC can be used in any application where an inbound data or control liner needs to be buffered, transmitted, or translated. In addition to the ten-bit buffer/driver, the 74ABT244CPC also features two low voltage control inputs, two low voltage standby inputs, three high voltage control inputs, two hemi-power outputs, and two standard power outputs.

Working Principle

The 74ABT244CPC is similar to other IC buffer/drivers that use a clocked latch architecture. The chip is powered by two standard power supply rails, a supply voltage range of 2.3V - 3.6V, and an LVTTL compatible control voltage range of 1.4V - 2.4V. To maximize the performance of the chip, it is recommended to use low RC parasitics, implemented with short traces, direct coupled from the logic to the chip.

The 74ABT244CPC features a combinational logic portion of the latch, which is clocked externally by a clock signal to determine the output values. The clock input of the 74ABT244CPC is asynchronous, and the internal combinational logic of the latch is used to detect inputs that go low, high, or within a specified operating range. As the inputs are detected, the combinational logic translates the input voltage levels to match the level and valid logic values of the 74ABT244CPC.

The 74ABT244CPC features two power down inputs, which are used to put the chip in standby mode. When the two power down input pins are active, the chip is no longer actively driven and draws a very small amount of current. This allows the user to decrease the power consumption of the chipduring periods of low usage.

The 74ABT244CPC is designed to be used in applications that require high speed, low power, and reliable data integrity. It is also designed to handle both logic-level and voltage-level signals, making it a versatile and reliable choice for any application.
