HMC677LP5 / 677LP5E v05.0810 6-Bit SERIAL/PARALLEL SWITCH DRIVER/CONTROLLER Typical Applications Features The HMC677LP5(E) is ideal for: Accepts Serial or Parallel Data Compatible with TTL and CMOS Logic Microwave and Millimeterwave Control Circuits Complementary Outputs Test and Measurement Equipment 6-Bit Control Word Complex Multi-Function Assemblies Power-up State Selection Military and Space Subsystems Low Power Consumption Transmit/Receive Module Controllers Fast Clock Rate 5 Functional Diagram General Description The HMC677LP5(E) is a multi-function BiCMOS control interface IC which is ideal for driving the gates of FET and pHEMT based MMIC control devices. This unique IC can be used to simplify the control of microwave and millimeterwave transmit/receive modules, military subsystems, and multi-throw/ multi-port test and measurement equipment. The HMC677LP5(E) accepts serial or parallel data, and can drive up to 6 complementary sets of outputs. The HMC677LP5(E) also provides additional functionality such as a power-up state selection, adjustable output voltage levels, and a latched paral- lel control mode which allows multiple control devices to share a common data bus. The HMC677LP5(E) is ideal for controlling digital phase shifters, digital attenuators, digital variable gain amplifiers, and switching matrices embedded in complex microwave and millimeterwave assemblies.

It is activated when P/S is kept high. The 6-bit serial word must be loaded MSB first. The positive-edge sensitive CLK and LE requires clean transitions. Standard logic families work well. When LE is high, 6-bit data in the serial input register is transferred to the outputs. When LE is high CLK is masked to prevent data transition during output loading. When P/S is low, 3-wire SPI interface inputs (DATA, CLK, LE) are disabled and the serial input register is loaded asynchronously with parallel digital inputs (I0-I5). When LE is high, 6-bit parallel data is transferred. For all modes of operations, the outputs will stay constant while LE is kept low. 5 Parameter Typ.

Direct Parallel Mode - Outputs are changed by the Control Voltage Inputs directly. The LE (Latch Enable) must be at a logic high to control in this manner. Latched Parallel Mode - Outputs are selected using the Control Voltage Inputs and set while the LE is in the Low state. This will not change state while LE is Low. Once all Control Voltage Inputs are at the desired states the LE is pulsed. See timing diagram above for reference. Information furnished by Analog Devices is believed to be accurate and reliable.
