The 74HC245 is a high-speed Si-gate CMOS
device and is pin compatible with Low-Power
Schottky TTL (LSTTL). The 74HC245 is an octal
transceiver featuring non-inverting 3-state bus
compatible outputs in both send and receive
directions. The 74HC245 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 74HC245 is similar to the
74HC640 but has true (non-inverting) outputs
