This is a kind of Transceiver TTL.
Part Number : 74HC245
Function : Octal Bus Transceiver
Package : SO20, SSOP20, TSSOP20, DHVQFN20 Type
Manufacturers : NXP Semiconductors.
The 74HC245; 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).
The 74HC245; 74HCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HC245; 74HCT245 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.
