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. INTERFACE - SMT 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. 5-3 For price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or [email protected] HMC677G32 v00.0510 6-Bit SERIAL/PARALLEL SWITCH DRIVER/CONTROLLER Power-On Sequence If LE is set to logic LOW at power-up, the logic state of PUP1 and PUP2 determines the power-up state of the part per PUP truth table. If the LE is set to logic HIGH at power-up, the logic state of I5-I0 determines the power-up state of the part per truth table. The attenuator latches in the desired power-up state approximately 200 ms after power-up. The required power-up sequence is: GND, Vdd, Vee, Voph, Digital Inputs (I0 - I5). The relative application of input signal order of the digital inputs are not important. Deviations from this sequence may inadvertently forward bias ESD protection structures and damage them. For added protection you may install 2 kOhm resistors in series with each digital input signal line, however these resistors will increase the RC time constant.
