ZONKY semiconductor provides a broad range of IC options for the MIL-STD-1553, Discrete-to-Digital and ARINC 429 IC product. For MIL-STD-1553, The most highly integrated products provide full protocol and transceiver functionality on a single IC, along with BC/MT/RT, on-chip RAM and dedicated host interface options. 
ZONKY’s range of Discrete-to-Digital components provides a robust solution for sensing Open / Ground and 28V / Open discrete signals. These devices are typically used in simple sensing applications.  
ARINC 429 ICs cover a whole range of complexities, from simple analog bus interface chips such as line receivers and line drivers to protocol ICs with on-chip FIFOs or RAM. Holt’s unique approach provides fully integrated solutions with both analog transceivers and digital protocol on one chip.
