The 74HCT245PW from Nexperia is part of the 74 series of Transistor–Transistor Logic (TTL) integrated circuits. This particular model is an octal, bidirectional, non-inverting bus transceiver with tri-state outputs and is offered in a narrow 20-pin TSSOP (Thin Shrink Small Outline Package). The device is a modified version of the original 74HCT245 designed for higher speed logic systems, while maintaining full compatibility with the 74HC245. It is designed for operation at 2.5V, 3V, 5V, and 12V and offers high data rate and low power consumption. The device is Factory Programmed with an 8 bit identity, allowing non-conflicting devices to be daisy-chained together for faster and more capable serial communication. This part is RoHS (Restriction of Hazardous Substances) compliant, and is suitable for a wide range of applications.
