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.

DESCRIPTION about electronic component LVX273 and Industry web recommended

The semiconductor  LVX273 has eight edge-triggered D-type flip-flops with
individual D inputs and Qoutputs. The common buffered Clock (CP) and Master Reset (MR)
input load and reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each Dinput, one setup time before the
LOW-to-HIGH clock transition,is transferred to the corresponding flip-flop’s Q output.
All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage
level on the MR input.
The device is useful for applications where the true output only
is required and the Clock and Master Reset are common to all storage elements. The inputs
tolerate up to 7V allowing interface of 5V systems to 3V systems.
