The MM74HCT245SJ is an octal 3-state bi-directional buffer designed for asynchronous communication between data buses. Utilizing advanced silicon-gate CMOS technology, it offers high drive current outputs, enabling efficient operation even with large bus capacitances. The device is TTL input compatible and can drive up to 15 LS-TTL loads, making it suitable for interfacing between TTL, NMOS, and standard CMOS components. Key specifications include a typical propagation delay of 16 ns and a low power consumption of 160 µA. The MM74HCT245SJ features one active low enable input and a direction control input, allowing data flow to be easily managed between the A and B buses. It operates within a supply voltage range of 4.5V to 5.5V and has an operating temperature range of -55°C to +125°C. The device is available in both SOIC-20 and TSSOP-20 packages, providing flexibility for various design requirements.
