The 74HCT244D.653 from NXP Semiconductors is an octal buffer/line driver designed for 3-state output applications. This device can function as two 4-bit buffers or a single 8-bit buffer, controlled by two output enable signals (1OE and 2OE).
Key electrical characteristics include a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various system designs. The device supports both CMOS and TTL input levels, depending on the specific variant (74HC244 vs 74HCT244). It offers high noise immunity and low power dissipation typical of CMOS technology.
Environmental specifications include operation across a temperature range of -40 °C to +125 °C. ESD protection is robust, exceeding 2000 V for Human Body Model (HBM) and 1000 V for Charged Device Model (CDM).
Available in multiple package options such as SO20, TSSOP20, and DHVQFN20, this buffer/line driver is suitable for surface mount applications. Its 3-state outputs allow for efficient bus interfacing.
