scope:

This drawing documents five product assurance classes, class D (lowest reliability), class E, (exceptions), class G (lowest high reliability), class H (high reliability), and class K, (highest reliability) and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-PRF-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type(s) shall identify the circuit function as follows:

Device type Generic number Circuit function 01 ACT4455 +5 V, single channel, MIL-STD-1553 transceiver (standby low) 02 ACT4459 +5 V, single channel, MIL-STD-1553 transceiver (standby high)

This device class designator shall be a single letter identifying the product assurance level as follows:

Device class Device performance documentation D, E, G, H or K Certification and qualification to MIL-PRF-38534

The case outline(s) shall be as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style 3 CQCC1-N28 28 Leadless chip carrier

The lead finish shall be as specified in MIL-PRF-38534.
