Product Summary

The 74HCT245D is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL). It is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HCT245D features an output enable input (OE) for easy cascading and a send/receive input (DIR) for direction control. OE controls the outputs so that the buses are effectively isolated. The 74HCT245D is similar to the 74HC640; 74HCT640 but has true (non-inverting) outputs.
