On-chip resistors and 2.9V regulator provide the prescribed 110Ω termination for low power dissipation and high speed data transmission. All line connections can be disconnected from the bus with a single logic control line to reduce standby power consumption. Output lines remain high impedance without power applied. Each line is individually clamped at ground to dissipate negative-going glitches. The 2.9V regulator is current-limited and thermally protected. Regulated output is available for external circuitry. The REG5601 is available in 28-lead SOIC and finepitch SSOP packages and is specified for operation over the 0°C to 70°C temperature range.
