Product overview
Description
The M54HCxxx and M54HCTxxx series is composed of CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. They include a large set of gates, flip-flops, multiplexers, counters, bus interface and several other functions.
The maximum operating frequency of the HC/HCT series varies between 20 to 55 MHz at 4.5 V and 25 °C depending on the products.
All types of the series feature a total dose hardness at 50 krad(Si), a high single event latch-up (SEL) immunity and a wide operating temperature range.
Housed in ceramic hermetic packages, all the products of the series are ESCC qualified, making them ideally suited for use in space and other harsh environmental conditions.
The complete specification of each type is available from the ESCC web site: https://escies.org using its ESCC part number.
Dedicated technical notes provide additional information on:
- TN1181: Engineering model quality level
- TN0873: Manufacturing and quality specification of products in die form
- TN1292: 100 krad(Si) versions
- TN0985: "Class S equivalent" flow specification, for use of ESCC products in a MIL-STD-883 environment.
