Product Overview: 74AC244MTR by STMicroelectronics

The 74AC244MTR is a high-speed, octal buffer and line driver designed to provide interface buffering for a wide range of applications. Manufactured by STMicroelectronics, a leader in semiconductor solutions, this integrated circuit is part of the 74AC series, renowned for its advanced CMOS technology that offers a perfect blend of speed and power efficiency.

The device features eight non-inverting buffers with 3-state outputs, making it an ideal choice for driving bus lines or buffering memory address registers. The 74AC244MTR is equipped with two separate enable inputs (nOE) which control four buffers each. When an output enable (nOE) input is high, the corresponding four outputs are in a high impedance state, thus allowing for bidirectional operation of the bus lines.

With its wide operating voltage range of 2V to 6V, the 74AC244MTR is compatible with TTL levels and can be used in mixed 5V/3.3V systems. This makes it highly versatile for both modern low-voltage applications and legacy systems. The device is also characterized by its low quiescent current, further enhancing its power efficiency.

The 74AC244MTR comes in a TSSOP-20 package, which is optimized for reduced space and weight in printed circuit board designs. This surface-mount package allows for automated assembly processes, facilitating mass production and ensuring consistent performance.

Key features of the 74AC244MTR include:
