HCS138T
Data Sheet July 1999 File Number
Radiation Hardened Inverting 3-to-8 Line Decoder/Demultiplexer
Intersil‘s Satellite Applications FlowTM (SAF) devices are fully tested and guaranteed to 100kRAD total dose. These QML Class T devices are processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers, while maintaining a high level of reliability.
The Intersil HCS138T is a Radiation Hardened 3-to-8 Line Decoder/Demultiplexer. The outputs are active in the low state. Two active low and one active high enables (
E1, E2, E3) are provided. If the device is enabled, the binary inputs (A0, A1, A2) determine which one of the eight normally high outputs will go to a low logic level.
Specifications
Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HCS138T are contained inSMD 5962-95727. A “hot-link” is provided from our website for downloading. www.intersil.com/spacedefense/ne wsafc lasst.asp
Intersil‘s Quality Management Plan (QM Plan), listing all Class T screening operations, is also available on our website.
