The ISL8490IBZ-T is a high-speed single-channel, full-duplex interface IC from Intersil. This IC is designed to provide full-duplex RS-422 and RS-485 data communications in applications where maximum speed, robust buffering and signal conditioning are important. The IC includes an 8-leading edge pulse width modulated (PWM) drivers, an 8-bit programmable charge pump, a 3V precharged, rail-to-rail, differential receiver, and an integrated oscillator. The integrated oscillator utilizes external tuning resistors to minimize the driver and receiver skew. The INTL8490IBZ-T is manufactured by Renesas, and is available in a compact, RoHS-compliant, 8-lead WANNEAL 8LD -4085 5V RS-485 Transceiver package.
