SN74AHCT244PWRE4 Octal Buffer/Line Driver from Texas Instruments

The SN74AHCT244PWRE4 is a high-performance, octal buffer and line driver designed to facilitate the transfer of signals between two distinct voltage domains. Manufactured by Texas Instruments, a leader in semiconductor solutions, this integrated circuit (IC) is part of the 'AHCT' family, known for its advanced high-speed CMOS technology.

This particular device features eight non-inverting buffers and line drivers with 3-state outputs, which can be employed to drive lines or buffer memory address registers. The 3-state outputs ensure that multiple outputs can be connected together for bus-driving applications without the risk of current backflow.

The SN74AHCT244PWRE4 operates at a wide voltage range from 4.5V to 5.5V, making it compatible with TTL levels, while its inputs are capable of translating 3.3V to 5V logic levels. This characteristic is particularly useful in mixed-voltage systems, where interfacing between different logic levels is required.

Key features of the SN74AHCT244PWRE4 include:

• Eight non-inverting buffers with 3-state outputs
• Input voltage level translation from 3.3V to 5V
• Wide operating voltage range of 4.5V to 5.5V
• High drive current outputs (-32 mA I<sub>O, 64 mA I<sub>O) for driving heavy loads
• Low power consumption with ICC of 20 μA maximum
• ESD protection exceeds JESD 22

Designed for use in a variety of applications, the SN74AHCT244PWRE4 is ideal for interfacing with high-speed microprocessors, driving bus lines in computing environments, and buffering memory address registers. The device's robust construction ensures reliable operation even in the presence of environmental stressors.

Supplied in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, the SN74AHCT244PWRE4 is optimized for space-constrained applications while providing the necessary thermal performance for consistent operation. Its packaging is also designed for easy integration into printed circuit boards (PCBs).

For engineers and designers looking for a reliable octal buffer/line driver capable of interfacing between different logic levels, the SN74AHCT244PWRE4 from Texas Instruments represents a robust and flexible solution.
