MC33560Power Management and Interface IC for Smartcard Readers and Couplers | Integrated Circuits (ICs) | 3 | Obsolete | The MC33560 is an interface IC for smartcard reader/writer applications. It enables the management of any type of smart or memory card through a simple and flexible microcontroller interface. Moreover, several couplers can be coupled in parallel, thanks to the chip select input pin (pin #5). The MC33560 is particularly suited to low power and portable applications because of its power saving features and the minimum of external parts required. Battery life is extended by the wide operating range and the low quiescent current in stand by mode. A highly sophisticated protection system guarantees timely and controlled shutdown upon error conditions. |

MC33762LDO Regulator, 80 mA, 1 V, Dual Output, High PSRR, Low Noise, with On/Off Control | Integrated Circuits (ICs) | 3 | Obsolete | The MC33762 is a dual low dropout (LDO) linear voltage regulator featuring excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40 µVRMS noise level without an external bypass capacitor. Housed in a small µ8 package, this linear voltage regulator represents the ideal designer's choice when space and noise are at premium.The absence of external bandgap capacitor accelerates the response time to a wake-up signal and keeps it within 40 µs, making the MC33762 LDO linear voltage regulator a natural candidate in portable applications. The MC33762 also hosts a novel architecture which prevents excessive undershoots in the presence of fast transient bursts, as in any bursting systems. Finally, with a static line regulation better than -75dB, it naturally shields the downstream electronics against choppy lines. |

MC3403DOperational Amplifier, Single Supply, Quad | Amplifiers | 2 | Active | The MC3403 is a low cost, quad op-amp with true differential inputs. The device has electrical characteristics similar to the popular MC1741C. However, the MC3403 has several distinct advantages over standard operational amplifier types in single supply applications. The quad op-amp can operate at supply voltages as low as 3.0 V or as high as 36 V with quiescent currents about one third of those associated with the MC1741C (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. |
