Product Summary

The 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL) . The 74HCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HCT245 is an output enable input (OE) for easy cascading and a send/receive input (DIR) for direction control.
