Description Introduction about IC parts BP5220A, BP5221A

The electronic components BP5220A, BP5221A, electronic component BP5222A, are DC / DC  converters that use a pulse width modulation (PWM) system. They contain control circuits,  switching devices, rectifiers, and coils, and operate by only connecting an I / O  smoothing capacitor.

With a high efficiency of power conversion, the modules are available in stand-alone
9-pin SIP packages with no heat sink required. They can be applied to various purposes by  fine-adjusting the output voltage and switching on and off. With a wide range of input  voltage, the modules are best suited for obtaining a stable local power supply from a main power supply with a large voltage variation.

Description Introduction about IC parts 74LVX161284A

The electronic components LVX161284A contains eight bidirectional data buffers and eleven  control/status buffers to implement a full IEEE 1284 compliant interface. The device  supports the IEEE 1284 standard, with the exception of output slew rate,and is intended to  be used in an Extended Capabilities Port mode (ECP). The pinout allows for easy  semiconductor connection from the Peripheral (A-side) to the Host (cable side).

Outputs on the cable side can be configured to be either open drain or high drive (± 14  mA) and are connected to aseparate power supply pin (VCCcable) to allow these outputs
to be driven by a higher supply voltage than the A-side. The pull-up and pull-down series  termination resistance of these outputs on the cable side is optimized to
drive an external cable. In addition, all inputs (except HLH) and outputs on the cable  side contain internal pull-up resistors connected to the VCCcable supply to provide  proper termination and pull-ups for open drain mode.
