FN2473.3
Radiation Hardened Inverting
Features
• 3 Micron Radiation Hardened SOS CMOS
3-to-8 Line Decoder/Demultiplexer
The Intersil HCS138MS 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.
• Total Dose 200K RAD (Si)
• SEP Effective LET No Upsets: >100 MEV-cm2/mg
• Single Event Upset (SEU) Immunity < 2 x 10-9 Errors/Bit-
Day (Typ)
• Latch-Up Free Under Any Conditions
The HCS138MS utilizes advanced CMOS/SOS technology
to achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family.
• Fanout (Over Temperature Range)
- Standard Outputs - 10 LSTTL Loads
• Military Temperature Range: -55oC to +125oC
• Significant Power Reduction Compared to LSTTL ICs
• DC Operating Voltage Range: 4.5V to 5.5V
The HCS138MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
