The MM74HC245A 3-STATE bidirectional buffer utilizes advanced silicon-gate CMOS technology, and is intended for two-way asynchronous communication between data buses. It has high drive current outputs which enable high speed operation even when driving large bus capacitances. This circuit possesses the low power consumption and high noise immunity usually associated with CMOS circuitry, yet has speeds comparable to low power Schottky TTL circuits.

GL800USB is a high performance USB 2.0 Transceiver compliant with the UTMI (USB 2.0 Transceiver Macrocell Interface) Specification proposed by Intel. The UTMI specification defines a standard interface to USB 2.0 high-speed transceivers that enables common design across prototype and production implementations. The USB 2.0 UTMI Transceiver, which handles the low level USB protocol and signaling, and shifts the clock domain of the data from the USB 2.0 rate to one that is compatible with the general logic.
